Are You Ready for Football?

…Is your Projector?

The NFL kicks off today with the Bears hosting the Packers. I suspect most Chicago and Green Bay fans gave their projector a test run last week. No self respecting football fan would wait until the last minute right? Right?

If you are human like the rest of us, you were busy putting away your summer shorts and breaking out the flannel. That lamp worked last season. That means its OK for this season….maybe.

When a projector lamp starts to wear out, you don’t really notice. The decrease in brightness is very gradual. This makes it a lot easier to watch after a year or two of use. Remember, just because it’s lighting does not mean it’s OK.

5J.J3905.001 for BenQ W7000

This time of year is a perfect time to give your projector a quick cleaning. Vacuum out the air-vents and maybe give the vents a little blast of air. We have other blog posts about maintenance in detail. This is also a perfect time to replace your projector lamp if its getting old. Always change them before they fail if you can. Then you have a ‘known-good’ backup, a new bright picture and no chance of missing your favorite team start off the 2019-2020 season.

Check your projector lamp hours in the menu (some projectors do not offer this info, but most do). If you own a BenQ W7000, they use a 5J.J3905.001 projector lamp. If the 2000 hour life span is past 3/4 of it’s life (ie. over 1500 hours of a 2000 hour rating), then it is a good time to consider replacing the projector lamp. Especially if you are planning to use the projector more often with the autumn and winter sports seasons.

There are plenty of other reasons to replace your projector lamp. If you happen to be retired or retiring, like Andrew Luck of the Colts, then I definitely recommend replacing your projector lamp.

Are You Ready for School?

BackToSchool

I finished my schooling some time ago. TV’s may have been the CRT type and the internet may have had more AOL than it does these days but preparing for the return to school is something that happens at the end of every summer around here.

My question is are you ready? This is mostly pointed to teachers, administrators and instructional media folks. Anyone who has to deal with video projectors and projector lamps.

This time of year is perfect to make sure you are ready to use your projectors. Over the summer the lack of use can allow dust and debris to build up over air-vents and lenses. Take some time to give your projectors a once-over with a damp cloth(no cleaner or solvent, just damp with water). This will pickup any obvious dust, preventing it from being pulled inside and causing you grief down the road.

When you do turn on the projector, take a moment to see how many hours are on your projector lamp. If you are remotely near the end of the projector lamp’s life, replacing the lamp now would put aside another chance of projector failure at an inconvenient time.

I recommend replacing your lamp before you get the end of life warning. Once you have about 10-15% (1700-1800 hours) of the life left of the 2,000 hours, the projector lamp is going to be unreliable. Some projectors have 5,000 and even 10,000 hour lamp ratings. The 10-15% life left rule would still apply but at higher hours.

Change the projector lamp before it fails. Then you put your old lamp in the desk or closet and save it as a backup. Even with 5% life left, the projector lamp will be a good backup in an emergency. It’s always better to err on the side of replacing the lamp early than trying to play projector-lamp-roulette and pushing it past its rated life span. When people do this, it is not saving them any more. It is giving them a terrible picture, and putting the projector at risk for an expensive repair.

New projector lamps are always brighter. They always improve your picture and they are always more reliable than a worn or wearing out projector lamp.

When Recycling Is Not Beneficial

Recycling is good for the environment. It keeps trash out of landfills that can be put back into manufacturing. Recycling can lower the cost of raw materials. Most of the time recycling is the answer to many issues affecting our environment.

Recycle Logo

In one particular case, recycling is a terrible idea.

Recycling Projector lamps.

I do not mean scrapping the Projector lamp down and recycling its components. The glass, the metal, the plastic can all be recycled on it’s own.

I mean when the lamp has the old bulb removed and then a new or still working bulb is installed and then the projector lamp is sold as new or ‘Recycled Housing’.

Projector Lamp housings are made of consumable parts. Even though they do not have many moving parts, they do get subjected to a pretty taxing environment while they are in operation.

The average projector lamp runs at 500f or so inside the bulb reflector. The heat is cooled to a more reasonable temp once it gets to the plastic and the glass, but not too much less. This continues for the entire life of the projector lamp. That means the plastic and glass and metal has been exposed to wide temperature swings for 2,000-10,000 hours(depending on the model).

That amount of temperature swing (room temp up to a few hundred degrees) causes the lamp housing to degrade. On many lamps, there is a coating applied to the lens to protect and block ultraviolet and Infrared light. This coating degrades slowly and unnoticed until it lets too much UV/IR through. Once this occurs, your projector will be cooked from the inside out. In some rare cases, the IR/UV can be so strong it could damage your eyes!

worn out UV/IT lens
Lens is worn out but sometimes is used with a new bulb. Not a good idea
Worn Out Housing
This shows a well worn lamp that has plastic that is no longer suitable for use.

Another problem with re-used/recycled projector lamps is the degradation of the plastic. As the plastic is heated and cooled, the plastic properties begin to change. Projector lamps use glass fiber re-enforced plastic. The glass fibers will begin to ‘float’ to the surface. If you ever notice a ‘gray’ area next to the black in a lamp, that is where the glass fiber has begun to float to the surface. This causes the plastic to become less reliable structure wise. This can lead to a warped housing and the bulb being pointed away from the proper light path and may melt or cause a fire by heating an area that isn’t meant for light. The other issue with old plastic is the cooling air vents may no longer be as effective leading you to need a new lamp well before you should. These usually have short warranties or are a hassle to handle the warranty.

The connector is the most dangerous area of a recycled projector lamp. They connectors handle high voltage and high amperage. The need to be secure and strong. When a lamp gets used for many thousand hours, it will cause the connector to lose some of its flexibility. Then when it is re-installed, one of the metal pins can break loose from the plug and slide out of position without you knowing. This leads to a second arc/spark outside the projector lamp, inside the connector. The lamp connectors will then melt and burn into the TV or projectors connector.

Melted Connector for JVC
Connector melted. Projector needed $400 in repair work.

The amount of smoke it releases is impressive. This almost always requires the projector being sent somewhere for repair. The cost of a ballast and labor can be $350-500(or more). Many times, the projector is ruined and not cost effective to repair. This only means that instead of saving landfill space you are now adding a projector and a projector lamp to the trash.

Quite the opposite of recycling…

A smaller yet important issue with using recycled projector lamps is if your model uses one of the many on-board lamp timer modules. They are a small circuit that is built into the lamp. This records the run time and hours used. If the timer is not reset, you will not have a proper run time record and in many cases the projector will shut itself down in protest.

Timer Module
Lamp Timer Module For Sanyo,Christie,Eiki and Panasonic

Technically, this is because the projector thinks the lamp is worn out, but I say in protest as it doesn’t want to chance having a lamp explode inside.

Buying a new projector lamp with a genuine original bulb inside will prevent all of these possibilities. The cost savings on a recycled lamp are quickly surpassed by the cost of repair and replacement due to early failure.

A new projector lamp has a properly coated UV/IR cut lens, glass fiber evenly distributed throughout the housing, and a connector with strong connection pins.

A new projector lamp has little to no chance of melting inside your projector and damaging the internals.

Is It Time to Replace My Projector Lamp?

After watching Season 8 Episode 3 of the HBO Game of Thrones on my Optoma TH1060, it inspired a question that seems relevant. Is my lamp bright enough to watch videos or is it time to install a new lamp?

My lamp is still coming on so why would I consider replacing it before it actually fails?

Unlike many other types of lamps, a projector lamp will slowly dim as it ages. This is due to the type of technology used to make the lamp function. As I have described in other blogs, these use a ‘Short Arc Mercury Vapor’ technology. In normal people speak, this means there is no filament(small wire that glows to make light). Rather there are two small pieces of tungsten that sustain a small yet powerful spark between the two points. Those points are encased in a small glass tube that you see in the middle of your bulb.

When you sustain a spark, it is called an Arc. hey..that rhymes…

Normally an arc is not going to give off white light. It will be a mix of blue, white, lots of ultraviolet and Infrared light. This sort of light will not make a good picture. It will ruin optics and possibly your eyesight.

To get a more color correct picture, there is a mix of gasses inside that little arc tube. Using a minuscule amount of mercury metal as well as some other gasses, the heat of the arc makes that gas mixture glow with a bright white light with some UV and IR emissions. The UV is blocked by the glass of the lamp lens. The IR is blocked by either an IR block coating on the lamp lens itself (most DLP) or on a built in piece of glass in the projector( most LCD). If the IR is not blocked, it can heat up the components inside the optical path. They will melt or burn and ruin the projector. Fortunately every lamp we sell has its coating checked. That means the only thing left to watch out for is when the tungsten arc points inside the arc tube start to wear apart too far.

On average the tungsten electrodes are 0.8-1.3mm apart. This varies per bulb, per model of bulb or bulb size. On the bulb you will sometimes see this arc gap measurement in the part number. For instance the 280W bulb in my BL-FP280E shows an arc gap of 1.0mm. That gap will grow as the bulb is used. The tungsten starts to wear. Once the arc gap is wide enough, the bulb may not light when asked to. It also may flicker as the arc cannot be held uniformly due to the tungsten points becoming uneven with use.

This is where the lamp life estimations come from. Manufactures measure the light output of their projector until the output drops to a certain level. That level will vary of course and is not published. No matter. The point of this time limit is to make sure you are not trying to see a picture that should be bright enough but isn’t. I have heard claims that they set these time limits to ensure more lamps are sold. That might be partly true but in reality the lamps do lose their original brightness as they age. There are some symptoms to look for that will tell you if the lamp is wearing out besides the brightness. Because really, if you watch it often enough, you will not notice the lamp dim. It happens so slowly over such a long period that it is almost not noticeable. At least until you put the new lamp in and exclaim, “WOW! That is WAY brighter!”.

The first symptom is the lamp taking longer to come on. The lamp should reach full brightness pretty quickly. If the lamp seems like it is taking a few minutes rather than less than a minute to get bright, it might be wearing out.

Another is if the lamp seems to be ‘flickering’. I say flickering in a light-to-dark sense rather than colors flickering around. That is something else entirely for another blog post. The light-to-dark flickering is mostly the arc starting and stopping and then restarting again very quickly. Another cause is the arc ‘walking’ around the arc points. It will leave its optimum position and this will be obvious by the image getting dim and then bright again in less than a second.

More common than you would expect would be the appearance of specs of dust in image. You would think any amount of dust would appear but these projectors are designed to be able to work properly with a moderate amount of dust. This is even true with dust directly on the DLP chip in a DLP or on the LCD panels of an LCD projector. Dust is inevitable in a normal install situation. Manufacturers know that and design the light path to work “around” it. I say “around” because the a new or not highly used lamp will output enough light to flood out the dust so that it is not affecting the image at all. The light is so bright that the dust is invisible in the image.

When a lamp is nearing the end of its life, the light output has dropped to the point to where you may notice bits of dust causing spots on the screen that weren’t there before. While a good cleaning is good to do seasonally, no amount of cleaning will get rid of all dust. There will always be a little. Replacing the lamp with a new lamp should bring back the brightness so that the small amounts of inevitable dust will not show up anymore. This is always my first go-to when I hear about dark spots or ‘water spots'(its been described that way to me). If the visible anomalies are still there after the lamp change, then its something else, but most of the time that is the solution.

Lastly look at the age of the lamp. Manufacturers have all sorts of life-span claims. The average is 2000-3000 hours of use. This isn’t a guarantee of course. There are many variables that come into play such as ambient temperature. How many times the lamp it started per day(schools tend to go through them well under the rates hours). Plus dust buildup inside(lack of cooling shortens lifespans of lamps). Check the lamp time of your unit. If you are 75-85% through the lamps life, the light output is much lower than it was. Keep in mind the old lamp can be a nice backup. Put that new lamp in and put the old one away for a spare.

These days, you can even download a light meter for your smart phone. Take a brightness reading(notice I do not say lumens, that is for another article). It’s arbitrary but that is OK as its for your projector only.

Then in a few months, measure it again using the same image. I prefer a white picture(YouTube has plenty of 10 hour white image vids). You can then start to get an idea of how fast or slow the lamp is wearing out. Once you get to 50% of the brightness it should be pretty obvious and you can put the next new lamp in.

Ideally purchased from us of course!

To break it down into an easy checklist, read below

  1. Is the lamp taking longer than a minute to get to full brightness?
  2. Is the lamp flickering light-to-dark?
  3. Do you see any visual anomalies in the picture that weren’t there a few months ago? Do they look like spots or dark circles?
  4. Does your light meter ap say the image is now 50% of the original brightness?

If your answer yes to any of those, click here, put in your model or lamp number and get a new lamp sent out today!

That way when we head back to Westeros for the rest of season 8 we can actually see what happens in Game of Thrones…

Did I Buy a Counterfeit Lamp?

How do you tell if this OEM Philips bulb is really an OEM?

There is the cost. Was the lamp 50% less than most of the other listings of the same lamp?

Real DT01291 w/ Original Philips UHP Bulb Inside

Let’s use a Hitachi DT01291 replacement lamp. This is used in over two dozen units across four manufactures(Hitachi, Dukane, Christie, and Infocus). The original bulb is a Philips UHP 330W. This is a higher wattage bulb and not an easy one to substitute.

I purchased one of these half priced lamps myself to see how they could sell it so cheap (well under the cost of the real bulb itself!). After having to wait 2 weeks for the 2-day air shipment I paid for, the lamp arrived. It was stuffed into a USPS box with some paper as padding. Fortunately the lamp was also inside a box with some foam or it would have been damaged.

Bad housing for DT01291

First thing I noticed was the housing. The plastic was cheap looking. There were fingerprints on the lens (big no no) and there was a paper warranty sticker on the seam of the housing. The edges of the housing were sloppy. The mold used was obviously well worn. It was probably from an original lamp and had been discarded and then re-used by the housing company who made this particular housing. I may be wrong but in seeing where they blanked out the OEM name on the side, I suspect I am not. While not terrible or dangerous, having a substandard housing can cause cooling problems and alignment problems with the projector.

Next thing I looked at was the bulb itself. Philips has a very specific set of part numbers/codes used to track their bulbs. Each bulb can be traced back to where it was made and when and even who it was sold to.

Counterfeit Philips bulb
This is a real looking ceramic label, not enough to indicate if it is counterfeit or not.

The ceramic label on the side was the first code I look at. This particular bulb said ‘452/53 330/264W 1.0’ . Under it is the rest of the serial #, date code and manufacturer location code. That in itself looked OK. It wasnt until I turned the bulb over and noticed a piece of info that seemed to contradict the label. There is a serial number printed directly on the reflector. If it was a real Philips 452/53 bulb, the serial number on the bulb would have an aftermarket designation, “AMxxxxx”. This bulb had a new construction serial number. Meaning the bulb was made to be sold inside a new projector rather than a replacement lamp. The serial number as just the numbers without the ‘AM(aftermarket)’ in the front. This made me very suspicious…

The next and most definite place to look is at the arc tube/burner (referred to as burner from here on).

The burner is the glass tube that actually makes the light. This is the part that unscrupulous companies put into used bulbs by clearing out the old burner and cementing in a new burner. They then pass them off as new OEM bulbs.

The OEM burner should have another serial number actually molded into the end of the burner near the tip. You should be able to read it or at least see that its there. If there is no serial number and the bulb is supposed to be an OEM, you can safely believe it to be counterfeit.

Counterfeit Philips 452 bulb
No Serial number was etched/molded into the burner.
All OEM Philips Bulbs have a serial number on the end.

I even went as far as to contact Philips directly and they were able to confirm my findings. The bulb here was sold originally to a real company and was then likely sent back as a recycle bulb. Normally the bulbs are crushed and used to make new glass(it’s good quality glass). In this case the bulb had the old burner removed and new, non-oem burner cemented it.

This is how the company was able to sell what they called an OEM bulb inside for more than half the cost of everyone else.

Being that I can’t confirm they are doing it on purpose, I will not be disclosing their name. It really doesn’t matter as there are many companies doing this. This company just happened to be the one I bought from.

It is up to you as a consumer to make an informed choice. The too-good-to-be-true holds fast here.

If you aren’t sure if the deal you are seeing is worth it, I would recommend calling around. Call us of course (1-800-664-6671) as we can guarantee our lamps are properly made without replaced burners or counterfeit bulbs. The pricing should be within $20-30 or so no matter who you call. If the price is $100 less with one company, you can figure they have a counterfeit lamp and play it safe buying it elsewhere.

5 ways to Avoid Buying Counterfeit Projector Lamps Online

Counterfeit lamps are a problem for everyone. From the companies who sell them (either willingly or through ignorance) to the end users who end up with damaged or non-functional equipment because of it.

How can you protect your wallet and your projector from counterfeit lamps?

  1. This applies to most things in life. “IF IT SEEMS TOO GOOD TO BE TRUE, IT PROBABLY IS” I cannot re-iterate this enough. If you read an advert for a lamp that uses an “OEM Philips UHP Bulb” and the price is significantly less than a comparable listing, then you are probably buying a counterfeit bulb.
  2. Look at the companies reviews with a grain of salt. I notice that some of the more ‘questionable companies’ tend to have five-star glowing reviews all in groups and they all tend to be within a day or 2 of each other. That is followed by no reviews for a week or so and then usually a reasonable amount of negative reviews. Those tend to be people who were duped by the ‘stuffed reviews’ that convinced them to buy the lamp they thought was a good deal. Many of those less than honest companies do this every few months. Sometimes they even change their name and start the dance all over again.
  3. Check the online forums.Make sure they require a confirmed order and that they check the reviews to make sure they legitimate end users. There are other sites like r/hometheater and AVSforum but they should be taken with a grain or five of salt. It’s possible for fake or erroneous reviews to be posted there. Always trust your gut.
  4. Look at the warranty. The longer the warranty, the better most of the time. That said, the long warranty can be a gamble by the company to make it look like they stand behind a great product when in reality they are banking on the chance that if the lamp fails you will forget its under warranty and not exercise your rights. I am slightly biased as our warranty is 6 months but I think that is a reasonable length. If you lamp lasts at least 6 months, the chances of it lasting the rest of it’s rated life-span are very reasonable. It is the “One year” warranties that concern me. If you need to cover your lamp that long, then why? Is it that unstable of a manufacturer that it might fail from a build error in 9 months? These are questions to ask yourself.
  5. How are the listings worded? Do you see “OEM Equivalent” or “Made from OEM parts”? OEM means Original Equipment Manufacturer. OEM Equivalent means its not an Original, but equal to it. That is a curious way to say “compatible”… Listen to that little voice that tells you it doesn’t sound right. Add up the red flags. Way too low of a cost, Way too long of a warranty and tricky wording on their listing. All of this means you would be better off looking elsewhere.

Is Your Projector Ready for Super Bowl?

I’m sure you can picture this situation. It’s SuperBowl Sunday and that one team you hate and the other team you love are slugging it out. Mostly killing time until the you get to watch the Halftime commercials. Then as the commercial break begins you hear a loud pop and the lamp LED starts flashing as the fan in your projector kicks into over-drive. Your projector briefly sounds like a 747 getting ready to take off.

Your heart sinks as your friends look around confused. You know your lamp has failed and let you and your guests down.

But why?

You just put the projector in 4 years ago.

You barely watch it.
Well maybe you watch it more than barely but you already reset that nag screen telling you to replace the lamp.

Why replace the lamp? Its still working, just reset the nag screen.

These thoughts all run through your head for what seems like an hour when in reality its been less than a minute as the jet engine projector is still whirring its fan to cool down the now failed lamp.

Your projector was designed by some pretty smart folks. The team involved was a group of engineers from multiple disciplines. Software, Mechanical, Electrical, Optical, even Ergonomic engineers all pooled their talents to create a device that was cost effective, feature rich and fulfilling for you, the end user to enjoy for many years.

One of the design aspects is the lamp and lamp control. That lamp is running very hot. It contains what is essentially a constant bolt of lightening inside its quartz envelope. It uses that lightening bolt to excite some gas that creates the light that gives you your images.

Those projector engineers know that the lamp will inevitably wear itself out. The temperature at the center can be over 500 degrees. Your projector works hard and well at keeping that heat manageable, ensuring you get your rated lifespan. The projector even warns you that your lamp is probably been beaten to the point that it needs replacement.

To make this a little more clear, let’s pick a great home theater projector.

The Epson Power lite Home Cinema 3010 is a great home theater projector. While a little more than 6 years old, this unit possesses the specs that make for a good video. 2,200 lumens with a 10,000:1 contrast ratio give you a clear and vibrant image in most if not all home theater rooms. This projector is one that has a rated lamp life of 4,000 hours in standard power mode. That give you the 2,200 lumens. You can save some lamp life if you have an extra dark room by using ECO mode and running the lamp at a lesser power. This will give you around 5,000 hours of use before you need to be concerned about lamp failure, but at a lesser vibrant image. Depending on the install, this may not be a concern.

When the Powerlite 3010 reaches the end of its rated lamp life, it will give you a subtle hint by flashing “Replace the lamp” on the screen. This is not really a suggestion. It is not Epson trying to trick you into buying a new lamp with your first born. It’s really a feature that the team of engineers built in to make sure your projector keeps running properly.

Fortunately for you and them, you can purchase a replacement lamp from Pureland Supply and save a few bucks in the process. Our lamps are designed to replace your original without sacrificing the quality designed into the projector. Our lamps use the same cooling features and bulb specifications as the engineers called for when the projector was made. You can see the ELP-LP68 lamp for sale here.

With the SuperBowl airing next weekend, it is a great time to give your projector a once over and even order a new lamp to make sure you do not end up watching it on your smart phone because the projector is doing its 747 impression for you and your friends.

Happy Holidays From PurelandSupply.com

We want to take a moment to wish everyone a Happy and Prosperous Holiday for 2018.

This is a great time to remind you to give your projector some much deserved attention with a good cleaning.  Get ready for 2019 with a projector that is ready to perform as you need it to:  Quietly, brightly and without issues.

Here are a few tips for some holiday maintenance.

  1. Clean the outside with a damp cloth.  If your projector is ceiling mounted, there will be dust build-up on top.  That dust can get sucked in and build up in the fans/ducts.
  2.  Unplug the power, remove the lamp and put your wand attachment on a vacuum. Give the lamp a gentle pass with the wand to pull off any surface dust. Then put the wand up inside the lamp well and pull out any dust building up on the surfaces or near the vents inside the lamp well area.  The goal here is to draw out any dust build up in the lamp fans.  You will not likely see those since they send to be inside the projector rather than exposed.
  3.  Run that vacuum with a brushed attachment across all of the vents on the outside of the projector.  That will help remove any build up that is going to be pulled inside. Any dust you remove is possibly another hour of lamp life that wasn’t there before. It can add up.
  4. Re-install the lamp but leave the power unplugged for the last part.  Clean the front of the projector lens with a clean dry cloth or microfiber ideally.  Stay away from solvents or soap cleaners. They can and will damage your lens if used incorrectly.  Use the clean dry cloth in a circular motion to wipe the lens from the center out.  picture a spiral pattern moving outward.  That will prevent smudges and give you the very clean lens.

To everyone and your family, please have a safe and happy holiday season and we hope 2019 is even better!

 

Thank you

Can I Buy a Brighter Lamp for My TV or Projector?

One question we get fairly often is,  “Can I buy a brighter lamp for my projector?”  or, “My TV says it’s a 150 watt bulb. Can I buy a 200 watt bulb?”.

The answer is No.  Thanks for reading!

 

Just kidding…

I take that back.  Technically yes, you can buy a 200 watt bulb for your TV but it will definitely not be brighter.  Front Projector and Rear Projection TV lamps are not the same kind of technology as an Incandescent lamp.  When you put a new bulb in your desk lamp and want it brighter you would look for something with higher wattage and you would get brighter light.  If the old bulb was a 75 watt and you screw in a 100 watt you definitely had more light so why not the same thing on a projector lamp?

Projector lamps rely on a dedicated power supply whose only job is to make sure the lamp installed runs at the proper power rating it is designed for.  The projector lamp ‘takes’ power from the power supply. Where as an incandescent lamp ‘takes’ power from the wall socket.  The projector lamps power supply is designed to run and supply the wattage the lamp is designed for.

For example. Your 200 watt Epson Brightlink 435Wi lamp has a power supply that pushes 200 watts of power to the bulb.  If you put in a 300 watt bulb, the power supply is only going to feed 200 watts of power. That bulb will only put out 200 watts worth of light even though the rating is 300 watts. In some cases it may even put out less than 200 watts worth of light…

It is similar to stereo speakers.  If your stereo has 100 watts per channel and you hook up 200 watt speakers, your stereo is not going to be any louder.  You would need a stereo that put out 200 watt per channel to get more volume(not really that much more but this is about projector lamps so I won’t get into logarithmic increases).

This is why you cannot merely purchase a brighter lamp.  Projectors are designed to run with the wattage lamp for all sorts of reasons.  Mostly cost related but also image quality related.  I have seen people who have installed higher output power supplies into projectors to get more brightness and the image looked washed out.  The contrast suffered because the projector was designed for a certain amount of light to be pushed through and exceeding that caused the image to look poor.

Your best bet for having the brightest picture possible is to minimize light pollution in your “theater” room. Blackout curtains, putting black tape over the myriad of things with indicator LEDs.

The most important things are to make sure your projector is clean and your lamp is new.  That will get you the brightest image every time.
