Light Sources For Power Projectors
Lamps:
These are just basic light bulbs. They are reasonably bright and tend to be inexpensive. The biggest issue with standard lamps is the relatively short lifespan. Although they tend to be rated for thousands of hours of use, LEDs and lasers just last longer.
LEDs:
LED projectors are either DLP or LCD projectors that use LEDs instead of standard incandescent lamps as the light source. LEDs last much longer and require less maintenance than standard projector lamps. LEDs are common in portable projectors.
Lasers:
Lasers are a newer type of light source in projectors that can produce a very bright, high-contrast image. Lasers have the advantage of never burning out and being very energy-efficient. The disadvantage of laser projectors is that they tend to be extremely expensive (we’re talking an easy five figures). For most people, it’s overkill, but if you really want the best of the best and have the cash to burn, we recommend the Sony VPLVW885ES
