The number one complaint is brightness, number two is longevity.
I should add for your information, from elsewhere on the internet:
Who Makes Projector Lamps?
High quality projector lamps that meet industry standards are only made by a few projector lamp manufacturers in the world. Manufacturing projector lamps is an incredibly expensive and challenging technological process that only a few companies are able to meet.
The major manufacturers in the projector lamp industry are -
- The pioneer of the projector lamp world. In 1995 they began researching and developing the first metal halide lamps. They eventually developed a mercury vapor projector lamp, which they called a UHP lamp or ultra-high pressure mercury vapor. The new development made it possible for projection systems to emit a brightness never before seen, and made digital projectors possible. Philips remains a dominant force in the projector lamp industry, and some estimates indicate Philips has more than 70% control over the projector lamp manufacturing and sales market today worldwide.
- Founded in Japan, but now with offices around the world, Ushio manufactures hundreds of different industrial lights, lamps and bulbs. The company started in1964 as an industrial light manufacturer. Ushio manufactures projector lamps for Sony, Sanyo, BenQ, and many other companies. Estimates indicate they have a 10% share in the projector lamp market.
- Osram started in Germany. The company specializes in producing the ARC tube in mercury vapor lamps and metal halide lamps. Osram claims to be the second largest lighting manufacturer in the world, with about a 7% market share.
- There’s a handful of projector lamp manufacturers in Taiwan, Japan, and China. The most notable is Matsu****a, which is a subsidiary of Epson and manufacturers all of Epson's lamps. Most smaller manufacturers of projector lamps don’t produce high quality lamps and aren’t commonly found in new projectors.
