Tips from Pureland Supply on how to increase Projector Lamp life
1. Handle the Projector Lamp with gloves. Oils and deposits from hands and fingers can cause
hot spots on the Projector Bulb, which may result in premature Lamp failure.
2. Operate your projector in a clean, cool, and well ventilated area. A dust free environment
would be ideal.
3. Keep the projector air filters clean. Clogged filters and/ or vents will not vent heat properly,
and can cause the Projector Lamp to overheat and fail.
4. Do not place anything on top of the projector or in front of the intake or exhaust vents. This
will cause the Projector Lamp to overheat and fail.
5. If the projector is built into a compartment, wall, ceiling, or shelf mount, the minimum
distance requirement (which is usually at least 2 feet) listed in the user manual should be
6. When you replace the Projector Lamp housing, make sure the new housing is seated
completely and securely. Apply pressure at the base of the Lamp Housing until it is
7. Hot Projector Bulbs are very fragile. Do not move or shake the projector until the Projector
Lamp has completely cooled. Shock and vibration applied to hot Projector Lamps may cause
the Projector Lamp to crack or break.
8. Do not unplug the projector until the Lamp has properly cooled. After the projector has been
shut off, the fan will remain on for about 5 minutes. This aids in cooling the Projector Lamp
evenly and completely and decreases the chance of early lamp failure.
9. Do not turn the projector on and off frequently during presentations. Each time the projector
is switched on, the inrush of power causes stress on the Projector Lamp. Try to minimize
your on/ off cycles by not frequently turning on and off.
10. Wait one hour after cooling to turn on again. After prolonged use (Over 3 hours) and
shutdown, wait at least one hour to turn the projector on again. If a lamp is still warm/hot, the
projector will send too much voltage early in the Projector Bulb heat-up cycle which will
drastically decrease lamp life.
11. Run the projector for approximately two weeks and/or 20 hours shortly after your purchase.
If the lamp is defective, it'll usually fail within the first 10 hours of operation. Some
projectors offer "low lamp" or "economy mode" options. Use them whenever possible. These
options have been developed to extend projector lamp life.
12. Have your projector serviced and maintained every 2 years. Maximize optimum usage
and life of your projector lamp and have a qualified projector lamp technician give you
advice on your Projector and recommended maintenance every couple of years. Call
