The BenQ CH100 is a slick, small, HD resolution, DLP portable business projector with an LED light engine, claiming 1,000 lumens. The lamp-free quality of this projector gives it an advantage over its lamp-based counterparts, most obvious in the rated lamp life. The CH100’s light source can last 20,000 hours at full power, 30,000 in Eco mode. By comparison, I reviewed a similarly-priced lamp-based crossover (business and home) projector, which could get up to 8,000 hours in Eco mode. That provides an excellent value proposition when considering that you would need to change that lamp just under four times before the LED light of the CH100’s engine will need maintenance.ssss
The 1000 lumen rating is, these days, is less than half of most lamp based competitors, and more typical of the brightest pocket projectors (which are LED powered but smaller). BenQ, however, offers up the CH100 in a competent attempt to cross a pocket projector with a "real" full sized one.
The CH100 is very portable and slim, weighing in at just over five pounds. It’s a short throw projector, but has a longer throw distance than is average for show throws. It sits a full two feet back from where the Acer (recently reviewed) was to fill a 92-inch screen – putting it at nearly six feet back from the screen (though for business and education applications, it's not likely that you will need to fill a screen so large). The BenQ CH100 handles ambient light fairly well, but you’re likely to want to have at least some degree of control over the lighting in the room. This projector is a definite contender for those where portability, price, and picture are of great importance.
