Incompatible parts and mishandling can reduce the life-cycle of projector lamps and replacing them can be costly. It`s essential to understand how to choose the correct replacement. In this projector lamp buying guide, we`ll discuss how to tell when it's time for a replacement and ways to increase the life expectancy of your new projector lamp bulb.
How to Tell When to Change a Projector Bulb
Most projector lamps last between 1,500 and 2,000 hours, but some can last up to 5,000 hours. Most projectors will need one to two bulb swaps during this time.
Unlike other bulbs that go out once expended, the high-pressure mercury and xenon used in projector lamps cause bulbs to dim over time. Once the lamp light is at about half its original luminescence, it`s time to replace it. You can continue to use the bulb until complete failure, but doing so impacts image quality.
Check how many useful hours your lamp has left in the menu options of the projector. User manuals have specific steps for this process.
Manufacturers and product testers judge life expectancy based on a bell curve of a bulb. Most projector lamps come with a 90-day or 3-month warranty instead of a warranty that reflects its rated life span.
Lamp Replacement Options
The easiest way to get a compatible bulb is to buy an original equipment manufacturer (OEM) projector lamp replacement module designed for the projector model in question. Some companies make copy bulbs for cheaper alternatives. Get a bare projector lamp without the housing and refurbish the existing housing, but there are minimal risks in doing so.
OEM Lamp Modules
A lamp module includes a plastic heat-resistant housing, a bulb with a burner and reflector and projector connectors to secure the unit. Often, manufacturers reduce the cost of lamp modules to encourage users to use OEM replacement parts.
OEM parts often have life cycles more consistent with their expected ratings. They`re also a guaranteed fit and work with the projector as intended.
Lamp Copies
Third-party companies make generic bulb replacements dedicated to specific projector manufacturers. It makes it easier to determine if a lamp is compatible with your projector. They`re less expensive than OEM lamp modules, but not always as high-quality, leading to inconsistent life expectancies. It`s possible that using a non-OEM lamp will void a projector`s warranty, so read yours carefully before purchasing this type of replacement.
When choosing a non-OEM manufacturer, look for companies that produce lamps according to ISO9001 standards. Quality alternative manufacturers are also more likely to have lamp warranties.
Bare Lamps Without the Casing
Some projector users prefer projector bare bulb replacements without the casing. For this method, you`ll need to carefully remove the old bulb from the existing housing with a screwdriver and refurbish the case.
Note that lamp cages are not designed for disassembly and are often difficult to put back together.
Additionally, dust buildup on the case is very difficult to remove. If you leave any dust on the cage, it can lead to over-heating and cause the lamp to fail before its time.
To reduce possible damage, consider a new housing for bare bulbs.
