They are selling Rebel with board on it.. so that it can be mounted on the heat sink with ease....

Have you tried SSC P7 C-bin?? 900 lumen.... LOL
I have this on a flash light and it's might even match the low end HID search light

 

nope...but 900 lumens must be really nice! You know..i really need to upgrade my work flashlight... i might pick up one of these.

 

You have many options here..
