Here is an example of one called the Noisy Cricket, with a picture in post 63 and more info in post 66.
I have actually played with this light, and it really is like a miniature mule. If you looking for any kind of a spot in your beam then you need a larger reflector for use with these 4 die emitters. Without effective optics, the P7 has limited use since at the modest drive levels attainable with one AAA battery you can't get high enough lux to allow you to see well very far at all.
Ahem, i dont think anyone saw this.
