Some Truths About Projector Lamps: OEM Versus Aftermarket

Share This Article

When it comes to replacing your projector lamp, the question often arises: should I opt for an OEM (Original Equipment Manufacturer) lamp or an aftermarket alternative? The answer might surprise you.

While OEM lamps have traditionally been seen as the gold standard, the reality is that many OEM manufacturers don’t actually manufacture their own lamps. Companies like BenQ, Epson, and Hitachi often outsource the production of their lamps to third-party manufacturers. These OEM-branded lamps are then sold under the OEM’s name.

So, what’s the difference between an OEM lamp and an aftermarket lamp that uses the same OEM-sourced bare lamp? In many cases, not much. If an aftermarket lamp uses the correct OEM-sourced bare lamp, the same high-quality components and performance can be expected. The key is to ensure that the aftermarket lamp also includes the correct housing, reflector, and IR cut filter. See this image gallery for pictures of what to look for.

An incorrect IR cut filter can lead to excessive heat buildup in the projector, potentially damaging the optical components. Authentic projector lamps typically feature IR cut filters with a distinctive red/blue/purplish tint, while counterfeit lamps often have greenish filters that are less effective at blocking infrared radiation.

When choosing an aftermarket lamp, it’s important to do your research and select a reputable brand. Look for companies that are known for their quality products and excellent customer service. By carefully considering these factors, you can find an aftermarket lamp that is just as reliable and affordable as an OEM lamp, while also ensuring that it has the correct IR cut filter to protect your projector’s optical components.
