Ok, I'll add my two cents.
I have a 'Radio Shack' LED flashlight. It's a "Flash Bright" (used to be sold at KMart). It is idenical to the Turtle Light case, color and all. I modded it and installed 7 white Radio Shack LEDs in place of the bulb. It still has one of the most pleasing beams judged by color. A little on the high blue side, but very bright and covers a large area too.
