I've got a couple Hellfighter lights. I cannot divulge any further information.
You can feel the searing heat from this thing, & see through your eyelids at 10 feet away. Imagine a criminal coming into your home with giant, night adjusted pupils ... then getting his brain fried by one of these.

I have 2 -- one big one, & another smaller one mounted to a ........ eerrr ....... device.
