No bulbs that I know of.
LCD's do have a brightness issue. While they DO last longer, you'll notice colors and overall brightness definitely takes a hit after time.
Also, it should be noted that while the threat of viewing headaches are near nil because the 30/60/whatever-pulsing Hz signal doesnt "flicker" on LCD's.. the image is still *laggy* compared to the competition. 10 milliseconds may not seem like much,but during an action movie or a fast pull/switch...there's still 'ghosting'. Nothing like technology pulling you out of your suspension-of-disbelief during a video game or flick, eh?
definetly ~lsd~ gives you the better reception
Am I the only one who caught that? Groove it.
