1 What is the Difference Between a Lamp and a Bulb?
A bulb is the core part of a lamp. A lamp consists of a bulb, an electrical wiring with connector and plastic housing. Plastic housings and electric cables can’t go wrong, just bulbs.
2 How do I replace a projector lamp?
There is a simple three-step process to replacing your bare projector lamp after you have removed the lamp housing from the projector.
- Unscrew the wires that are joined to your simple projector lamp.
- Remove the retaining clip that is holding your old bare projector lamp in place.
- Replace the old lamp by the new lamp and fasten the clip and two screws back into place.
If you are having the problem with this process, please do not hesitate to call or email us, we provide full technical support.
3 How do I Extend Projector Lamp Life?
Projector lamps usually terminate early because they are burning at too hot a temperature over the direction of their days. Below are some simple hints for increasing your projector lamp life.
- Ventilation –
The most important thing you can do to make sure your projector lamp lasts a long time is to install your projector in a space with enough ventilation. Projectors that are installed in corners, extremely close to the ceiling or in rooms with little to no air flow frequently cause the projector lamps inside them to expire early.
- Vacuum and Blow Compressed Air –
Dust inside your projector can produce the projector lamp to burn at too hot a temperature over time which will decrease its life short.
- Change or Clean Your Filter Regularly –
Almost every projector these days has a filter that blocks dust from getting inside the sensitive systems. The drawback to this is that if the filter gets jammed with dust, it can cause the projector lamp to burn at a tropical temperature and reduce its lamp life. The filter on your projector is usually found behind a small rectangular panel that measures 0.5″ by 6″ long.
- Do Not Turn Your Projector On and Off Quickly –
- Run Your Projector in Economy Mode –
Most projectors these days have a regular mode and economy mode. Economy mode usually makes the projector lamp emit a slightly lower brightness level and therefore can extend your projector lamp’s life. If you are unsure if your projector has economy mode, please reference your projector’s manual or contact the manufacturer
4 Why Are Projector Lamps So Rich?
Projector lamps function by burning ultra-high pressurized mercury vapor that is condensed inside a quartz ARC tube. Power jumps or arcs across the gap filled with mercury vapor lights it and produces an extremely bright light.
As you can guess, this technology is not cheap to produce. The machines required to provide a single projector lamp can often cost manufacturers tens of millions of dollars.
Projector lamp manufacturers also have to hire skilful scientists and engineers to ensure that the projector lamps are assembled to the standard required. The mercury vapor has to be pressurized at an exact pressure, and the ARC tube and quartz reflector also have to be structurally well. If these components are not calibrated with exact accuracy than the projector lamp quality will suffer seriously, or the projector lamp will decline to work at all.
Further, most projector lamps have various ignition and running voltages and wattages. Various settings produce different brightness levels or ANSI lumens rates. The machines that construct projector lamps, therefore, have to be recalibrated for each particular lamp setting.
5 Projector Lamp Prices are Falling Over Time
The good news is that as the years go by, projector lamp prices have fallen slightly and they are becoming more and more affordable for the average buyer. Every year more companies are attempting to manufacture projector lamps, and the competition drives prices down. Also, the return on investment for lamp manufacturers increases every year as they pay down the high start-up costs associated with manufacturing projector lamps.
6 Can I test my Projector Lamp?
Projector lamps are a complex and different technology than most household or traditional electronics, and therefore it is important to know certain facts when trying to test a projector lamp.
Projector lamps use customized ballasts that ignite the lamp by charging it with a higher voltage in the ignition phase and then dropping down to a lower running voltage once the circuit is created.
Projector lamps CANNOT be tested with a Multimeter. Projector lamps function by igniting ultra-high pressurized mercury vapor across an ARC tube. At the point where the mercury vapor resides there is no conductive electrical material and therefore testing a projector lamp with an AMP or OHM will not work.
Testing a projector lamp is impossible to do with your typical household electrical equipment. You must have specific testing machines or a related working projector when testing projector lamps
We sell the projector lamps in two formats – projector lamps pre-assembled in the black plastic housing and bare projector lamps without the housing.
7 My bulb exploded, can I still have it replaced?
A: Do not worry! The answer for most cases is yes. A blown or exploded lamp can be replaced.
8 How many hours will my projector lamp work?
A: Projector bulbs are similar to regular light bulbs as they have an expected operating time called a lamp life. The value is noted in hours and is representative of the number of hours it will take before the lamp emits only half of its original brightness.
Most projector lamps life span is approximately 2000 hours, but this varies based on the lamp’s technology and projector. A majority of lamps meet the lamp life hours specified, however, some lamps fail sooner as the success rate is based on a bell curve.
The projector lamp has a great chance of lasting throughout its entire rated life if it is used under normal conditions. Normal conditions include a three to five-hour usage per day, in a clean and dust- free environment.
9 Are Projector Lamps Compatible With Any Projector?
A: Projector lamps are specially manufactured to fulfil the unique technical needs of your projector. Requirements include the exact pressurization of the mercury vapor, the positioning of the ARC tube within the quartz globe at a precise angle, and manufacturing the ARC tube to withstand the mercury vapor’s ultra-high pressure.
As of today, no universal projector lamp exists. It is not feasible to install a 150W projector lamp into a projector that needs a 250W projector bulb; it is also not feasible to install a 250W lamp into a projector that may require a 250W bulb but requires a different ignition and running voltage.
It is advised not to install a lamp with the same ignition, running voltages, and wattage settings without also securing that the ANSI lumens rate is identical. If the ANSI rates are not identical, the projector will not function correctly. It will run too hot, and not release a bright enough image.
