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.
- 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.
- 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.
- 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.
- 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!

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!
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.
