Tips for making your DLP Lamp last longer
There are lots of good articles out on the web about making your DLP lamp life last longest possible time. I have tried to pull together the lists into one master list which is below. From what we have seen the following brands of Rear Projection TVs (RPTVs) experience the shortest dlp lamp life and therefore are our top sellers. There have even been various legal matters brought against these popular projector and RPTV manufacturers.
So the consolidated list of tips for making your lamp last longer are as follows:
(drum roll please….)
1. Once you turn on your projector, wait at least five minutes before turning it off to allow the fan to properly cool the unit. After the fan has cooled your projector, you may unplug it and store it as desired.
2. Do not obstruct the air intake or exhaust vent. Paper should not be placed on top of a projector, or where vents are located.
3. Keep the exhaust vent at least two feet from any object.
4. If the projector is built into a compartment, wall, ceiling or shelf mount, the minimum distance requirement (usually at least two feet) stated in your owners manual must be maintained.
5. Clean the projector’s air intake filter every three to six months — or more frequently — based on your operating environment. Proper ventilation will prevent overheating and untimely lamp failure.
6. Do not move your projector until the lamp has cooled (about five minutes).
7. Run your projector for two weeks and/or 20 hours shortly after your purchase. If the lamp is going to fail, it will usually occur within the first ten hours of operation. Lamp warranties typically last just 90-180 days from the date of purchase, rather than the first installation.
8. When you purchase a replacement lamp for your projector, remove the existing lamp and use the old lamp as your spare. If your projector is new, test the original lamp for the two weeks/20 hours before removing and storing as a spare.
9. Wear gloves during lamp installation. Oil and deposits from hands and fingers can cause hot spots, which can cause lamp failure
10. Hot lamps are fragile. Shock and vibration applied to hot lamps may cause the lamp filament to break. Wait until the projector lamp has completely cooled before handling.
11. Powering your projector on / off during presentations is not recommended. The inrush of power when the lamp is powered on causes stress on the lamp filament and can initiate damage.
12. Various projectors offer “low lamp” or “economy mode” options. Use this option when it is possible.
13. Once your projector goes off, do not turn it back on for at least an hour. A bulb must be stone cold when you start it, or the projector will send to much voltage early in the heat-up cycle, and you will drastically shorten the bulb life.
14. Do not turn a projector on in cold weather. If it is 40 degrees or below, your projector lamp will have a tendency to explode if you turn it on immediately. Same goes for hot temperatures. Never leave your projector in a car on a hot or cold day!
