The first LED flashlight that I had gave off a weak blue light, it's only saving grace was that it was small, and the batteries lasted forever. The one I presently use at work is about 4 inches long, with a 3/4 inch body and about a 1 1/4 inch head. It is as bright or brighter than a car headlight, makes a nice clean white light, and the 3 v lithium batterys last about 3 hours.
The technology is changing even as we post.
So, if we stop posting will technology stagnate?
The Goodyear blimp uses over 7,000 such lights. They call it the LED zeppelin.
