What is a "high bright LED" or a "higt bright LED"?
Some company must make it.
It must have a part number.
It must have a datasheet that tells all about it.
Speaking of such LEDs, watch out for the Nichia brand of ultra-bright LEDs that are comparable to the Luxeons, but at a much lower cost. I bought an Aurora clone flashlight featuring a 1.5w Nichia w/ constant current regulator and focused lens assy. for a mere $12. It's powered by two AA batteries and that light is d@mn bright!!! Impresses the hell out of everyone that has seen it. Waterproof alloy case too!
care to share a source for these "lower" than lumileds priced nichia? I mean, $2.99 for a 1 amp (3 watt) luxeon is pretty cheap... I suppose that's a North American price, I've heard they cost considerably more in Europe.

Well, a Luxeon 1 watt sells for $7-$8 US dollars on avg. here. Where are you getting that low price of $3 for a 3 watt Luxeon? I gotta get in on that deal!!!
I happened across the flashlight at a Target store, which is prolly the biggest competitor to WalMart. I even returned and bought their larger flashlight that runs off of two C batteries. However, there is no difference or increase in light output between both models. Remember, I'm buying an entire flashlight for $12, not just the LED. It's an incredible deal and the construction quality is right up there with Mag Lights. The Aurora brand flashlights sell for 3 times the price and I can't find any real difference between the two. I believe the private label is able to undercut the price of the Aurora. My son walked about a block away from me and turned on the light. It was so bright, it resembled a carbon arc!!
On a similar note, I ran across a fella during a camping trip who has his entire campsite illuminated by a strip of Luxeon leds running from a 12v deep cycle battery. He is a lighting engineer and was testing his design that is to be ultimately packaged and sold for use in the trailers towed by semi-trucks. I think he had about 8 Luxeons running and at first I thought he had hung up a flourescent fixture with two 4' lamps!! He was driving them pretty hard, beyond their specs to test their endurance. It was impressive, I admit. I expect vehicle headlights to go that route someday as the technology in both LEDs and CAD optics improves.
