HEAT = BADManufacturer
The number one cause of lamp failure is excessive heat. Follow the
instructions in the user manual for powering down the projector to ensure
1. Once the projector is turned on, wait at
least 5 minutes before turning it off to allow the fan to properly cool the
unit. You do not need to unplug the power to the
projector. I should stay in "sleep" mode (red light on) unless you see smoke
or flames coming out of the projector! We have install "quick release"
access points on all projectors in the district with a small surge
protector. The "quick release" is for emergencies and/or for projector
2. Don’t obstruct the air intake or exhaust vent.
Nothing should obstruct air flow to the vents.
3. Keep the exhaust vent at least 2 feet from any object.
Do NOT hang paper near the projector.
4. If the projector is built into a compartment, wall, ceiling, or shelf
mount, the minimum distance requirement (usually at least 2 feet) listed in
the user manual must be maintained from any other object.
5. Clean the projector’s air intake filter every 3 to 6 months, or more
frequently based on the operating environment. Ask the
Tech Department to assist you with this procedure.
6. Run the projector for 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. Lamp warranties typically last just 90 to 180 days from
the date of purchase, rather than the first installation.
Report any failures at anytime to the Tech Department as soon as failures
occur. DO NOT WAIT!
LAMP LIFE SPECIFICATIONS
Lamp life is measured to industry standards,
specifying a 2 hours on and 15 minutes off cycle.
HOW LONG WILL IT LAST?*
• Halogen bulbs: 70 hours
• Tungsten: 1,000 hours
• Metal halide (high pressure mercury): 1,000 to 2,000 hours
• Xenon short-arc: 400 to 2,400 hours, depending on type
• UHP (ultra-high performance by Philips): up to 4,000 hours
• HID (high-intensity discharge): 6,000 hours
*(normal use, estimates only)
BASIC LAMP TYPES
Halogen Lamps — These bulbs produce a warmer
image onscreen. This lamp technology has been around for some time, and is
found in many different types of projectors. When these lamps burn out, they
do so immediately, so it’s important to have a few backups ready to go.
Metal Halide Lamps — These lamps produce a characteristically cooler image
onscreen. As they age, they tend to fade slowly over time. When the image on
the wall doesn’t seem to be as bright as it used to be, it’s probably time
for a new bulb.
2,000 hours = 1 year.
Under normal circumstances, a lamp rated at
2,000 hours should last about a year, operating 7 hours/day, 5 days/week.
THE DO’S AND DON’TS FOR
PROLONGED LAMP LIFE
• Use the projector in a normal environment (avoid extreme humidity,
temperature, and dust).
• Clean the air/dust filters according the user manual. Blocked filters make
the lamp overheat and fail sooner. Manufacturers can test for this kind of
failure, and any warranty becomes invalid. Always ensure that there’s good
airflow around the projector.
• Use a cloth or gloves for handling a naked bulb.
• Operate in “economy mode,” if it’s available with your projector model.
• Switch off main power before cooling down the lamp, according to the user
• Switch lamp on/off in short cycles (e.g., 5 minutes on, 5 minutes off.)
• Touch the lamp (in cold or operating condition) without gloves.
• Bump the projector when it’s operating.
• Move the projector during operation.
• Allow the projector to become overheated.
anything on top of a projector or cover a projector while in use.
HANDLE WITH GLOVES
Deposits from fingerprints on the projector
bulbs cause temperature
“hot spots.” In the long term, the accompanying temperature gradient
stresses the glass of a bulb resulting in early failure.
MODULE OR NO MODULE?
The precise placement of
the lamp in the module is critical to lamp life, and it is recommended that
you buy the
lamp pre-installed in a module.
|ONLY Plug the
projector into a surge protector or (orange) dedicated computer circuit
(high school campus only). Otherwise, do NOT plug your projector
into a wall outlet.||
|Do NOT touch the
lens of the projector! Do NOT use paper towel to clean it. There are
specific lens papers that are made to clean the lens. If you do NOT have
one of these DO NOT CLEAN the lens.||
|Do NOT use the lens
cap to cover the lens while the projector is on. This creates heat
build-up and can ruin most projectors.|
|The projector bulbs
cost from $150 to $600 so DO NOT USE the projector unless you need to AND
DO NOT leave the projector bulb on when not in use.||
|Never turn off the
projector unless the bulb has cooled down!!! It is not necessary to unplug
the projector (or turn it off) during the time it is in your classroom.
The projector should stay in "stand by" mode at all times when not in use
(orange light on). "Stand by" allows the fan to cool the bulb. It is
very important that the projector stay ON while the fan cools the bulb.
Never turn the projector off at the toggle power switch unless the bulb
has cooled and you are planning to move the projector.
|Report any stolen
or broken equipment IMMEDIATELY!||
|Do NOT leave
unmounted projectors in an unlocked room.||
|The projectors that
are not mounted will
need to be turned in to the Tech Department before holidays and summer
vacations. Do NOT lock projectors up in closets or store for long periods
of time. Moisture can corrode the electronic components. The Tech Dept
will store the projectors over long vacations.||
|Do not set the
projector where it can be knocked off or where the power cord will trip a
student. Make sure you use the floor cable strips to cover the cords for
safety of students and the equipment.||
|Do NOT use the
projector as a glorified overhead. If you can show it on an overhead---use
the overhead. Overhead projector bulbs cost from $5.00 to $8.00 --
projector bulbs cost $150 to $600 each -- you do
the math! |
The CAMPUS is responsible for bulb replacement orders.

questions concerning the use of the projector, please feel free to contact
