I've purchased a number of "upgrades" for my aging LCD rear projector over the years, but few have provided such great "bang for the buck" as this LED bias lighting kit. With my viewing room darkened, the effect is dramatic AND highly effective. I'm noticing reduced eye strain, and perceived contrast seems to be improved (albeit slightly).Installing this kit couldn't be easier. The LED light strip is backed with a strong adhesive that holds securely, and the strip itself is easy to place and manipulate (even along my set's curved back). The included wiring and power switch are plenty adequate - all were easy to conceal, and the manufacturer includes adhesive-backed wire clips to aid in keeping the wires out of sight.The only nitpick I have so far is that the product doesn't seem to function unless it's plugged directly into an AC wall outlet - it refused to power up when I first plugged it in to my rack-mounted power center/surge protector. The manufacturer states as much on their website, however, so this didn't come as too much of a surprise. It will work just fine when attached to a basic household extension cord - only surge protectors seem to present a problem.The only other improvement that might benefit this product would be some sort of an IR-controllable switch, though for the price, I'm not complaining. It should prove relatively simple to add such functionality with a third-party solution. Installing this kit shouldn't take you more than five minutes, and the results will be both substantial and immediate. I recommend it heartily.
