Projector Lamps are the Lumens Source. The part of the projector that produces light is the lamp, which has a bulb. There are a variety of bulb types including UHP, UHE, halogen, and metal halide.The bulb is extremely important to the imageâs brightness.sually, the brighter the image, the sharper the contrast will be.
