It is based on a replacement LED bulb that an inventor I work with has just come out with. With this insert, a 60 lumen Surefire flashlight becomes a 240 lumen monster. The batteries also last longer, due to a heat sink that improves efficiency. This light is brighter than a car light, because I've driven at night in a car, shined the flashlight ahead onto the road, and you can see the spot in the pavement illuminated by the car headlights. It is unbelievably bright. I was camping next to a huge rock outcropping and I lit up the whole rock with this little tiny flashlight.

The parts of this system are as follows: 2 CR123 Batteries, AW Brand protected rechargables from Lighthound.com, $7 each.
