You _just_ noticed?

Hehehehe. And as far as the simple test goes, keep in mind that A) These 
should be the high-end ULTRA bright white LEDs. Those things are pretty damn 
bright. And B)You are going to be using a very large cluster. I've seen a 
number of different ways of trying to estimate how many you'd need, but a 
quick guestimate would be, oh, say 50. It'd be a pain in the butt to build, 
no doubt, but I think the payoffs (if it works) would be pretty good. Never 
have to replace it, runs cooler, hence quieter, cheaper (even with 150 leds, 
your cost aint gonna be the $400 a lamp could run ya), and uses less juice. 
To name a few. And you can get a pretty good brightness out of clustered 
LEDS, I've even seen a company selling LED car headlights.
