How to tell if the Lamp in your Projector or Rear Projection TV has Failed or is About to Fail
Here are 6 Basic Steps for Lamp Replacement.
lamp has two points on the bottom to grab the lamp for removal.
When the switch has been made, you can screw the new lamp housing unit into place and then re-attach the lamp access panel. Be sure to not over-tighten the screws. At this point, the users can reconnect the projector to the electrical outlet and turn on the project to see if the new lamp works. If the projector still does not work after the lamp replacement has been made, there may be a larger issue that is causing the problem. In this case, users should seek the help of professionals specializing in projector repair in order to determine the right course of action.

Projectors are fragile, expensive pieces of equipment that can perform for years if treated properly. Performing routine maintenance to the various parts of your projector (i.e. the filters, lamp, etc) will help to ensure that you are creating the best environment for your projector to operate. There are certain precautions you can take when using your projector on a regular basis that will improve your the lifespan and protect your investment.
- Allow the projector to completely cool down before moving it.
- Use the original box and packing materials to store the projector if possible. If the original packaging materials are not an option, use a strong box to hold the projector securely and at least 2 inches of a soft material (i.e. cloth, foam, etc) all the way around the projector.
- Remove the batteries from the remote control.
- When storing the projector make sure that the storage area will not be subjected to extreme temperatures (hot or cold) that could affect the projector.
- If you move a projector from one temperature extreme to the other, let it sit for 30 minutes or so until it rises or lowers to room temperature. This prevents moisture problems.

Your Source For Replacement Projector Lamps
LED (Light Emitting Diode) Projectors are on the market. They have been for a few years now. At first they were waffling between LED and Laser(which uses LED) and have settled on LED for the most part.
LED is touted as “No more lamps!” which is the biggest selling point.
Is this true? Its true that there is no lamp to replace in an LED projector. They have no removable user parts that can be replaced. Its a sealed unit and you are at the mercy of the manufacturer.
Is this a good thing? In my opinion, as it stands now, I say its not a good thing. There is a lot of promise in LEDs. They are not the lifetime lamp they claim to be.
Being someone who works inside projectors, its been my experience that LEDs are not there yet.
I will explain my thought and will be interested to see if my thoughts hold true in a few years.
LEDs themselves are fine. For general lighting, indicator lights and even low lumen, low cost projectors.
Inside a projector, the LED light engine is made up of 3 chips(In most cases). I’ll be referring to LEDs as Chips since they are semiconductors.
They use a Red, Green and Blue High output chip mounted to a large heat-sink arrangement. Those Chips are then powered by a special lamp driver made to run those Chips .
Current LEDs suffer from a problem that cause them to have a severe drop off in brightness after a certain point. That energy then becomes heat. The average short arc (current technology)projector is 3000-5000 lumens at 250-300watt.
For instance, the Optoma UHD60 uses a 240W Osram bulb that puts out 3000 lumens to the screen. This means the unit uses 240W of lamp power(not 240W total power) to drive the lamp.
An LED for the same unit would need to be at least 50W per color. That would then add up to 150W total (for RGB). The problem here is that at 50W the Chip is going to generate a lot of heat and put a lot of stress on the lamp driver. In most cases when an LED light of any type(even incandescent replacements in your home) fails, its because of the lamp driver rather than the LED element itself.
The amount of thermal stress increases greatly as the wattage increases. Most of the time the voltage is constant and the amperage is increased.
Over a few amps, the thermal reliability begins to drop off significantly. The diagram below shows the drop off of a high power Blue Chip that could be used in a projector.
Short Arc Mercury lamps such as the BL-FP240E for the above mentioned Optoma UHD60 and UHD65 on the other hand are tried and true technology. When the lamp fails in this model you can change it. That lamp usually lasts 2 years(with normal use). Then for a few hundred bucks you are back in operation and have a nice bright image.
If you want to use a long throw projector in an auditorium you are definitely better off with the current type of projector technology over LED. Even Laser which is advertised as effective will not give you the clarity and color rendering that a Short Arc lamp can currently deliver.
With the average LED projector warranty only being 2 years, you are then stuck with a multi-thousand dollar paperweight when the lamp driver fails or the LED overheats. There is no reset or simple bloated capacitor fix. It is going to need a new lamp driver module and probably a new LED module. In my experience those parts can be much higher costing than a plain old short-arc lamp.
Last projector I worked on with LEDs, would have cost $300 for three 25 watt red, green and blue chips. It still needed a lamp driver which was $150. For the low-low price of $450, the customer would then have had their $315 LED projector back in operation. Lesson learned.
Those lamp drivers and Chips are not user replaceable. There is no door you can open and pull a cartridge out and then pop in a new one. You have to take the projector down, ship it to a repair center and wait for it to be sent back. Inevitably it will fail again. Rinse and repeat.
With LEDs now starting to grow up, I fully believe they will be the light source of the future.
However as it stands now, they are not there yet. Don’t let yourself be part of the manufacturers experiments. Wait until you see a 4K 3000 lumen projector under $1000.
Until then buy an Optoma UHD60 or UHD65 and then in 2 years check back to see how BL-FP240E is going for and let me know if I was right about LEDs.

What is a Short Throw projector? I promise it’s not what you do when your lamp dies early..
Buying a new projector can be daunting. There are so many to pick from. Especially if you need a specific type like a Short throw. What is a short throw projector you ask and why might you need one?
Sometimes your space doesn’t allow for a standard distance from the screen. Many basements and home theaters allow the projector to be installed 10-20 foot back from the screen. Occasionally you need to mount the projector very close (less than 1-5foot back). The problem then becomes the image cannot be made large enough with the standard lens. This is where the short throw projector comes into play.
A short throw lens uses a special optical design that makes it easy to position the projector close to the screen without sacrificing image size. You will see this very often in schools.
When the schools use a Smartboard system, it relies entirely on short throw projectors such as the Smartboard UF55 which uses a 20-01032-20. This lamp with housing uses an original 215W Osram lamp, projecting 2000 lumens via the projectors short throw lens.
These models use the short throw lens design to allow a 100″ image from only 2 feet away. This allows the mounts to be very close to the screen. They both utilize a standard projector lamp, part # but allow a full sized image without sacrificing space.
This can be useful at home. You can use a smaller room and still enjoy movie theater-like image sizes. The Steelcase Polyvision PJ905 with a 2002031-20 lamp is a short throw projector that supports up to a 1080p input. There are other models that use short throw lenses as well. Picking the right projector will be a series in this blog by itself so I wont go into it here.
Using a short-throw projector at home can save you a lot of setup and configuration hassle. It opens up a lot of spaces that used to not be convenient for a projector. Even if you live in a narrow apartment, a short throw projector can work in as little as 10″ from the screen. Many projectors have a short throw lens as an option. That would manufacturer dependent. Buying a lens already installed is also an option.
