The original LAM manufacturer was Insight Technologies. The LAM consisted of a visible white light illuminator (incandescent, I would guess about 70 lumens), a visible red laser aiming device, an IR illuminator (IR Diode, worked well in CQB with NVG's) and an IR laser aiming device. I found the original device to be a bit delicate for its intended mission. I broke at least three of them. It was mostly the adjustment screws that would malfunction. The white light was on the same level, maybe a bit below, as the early Surefire handgun lights. Insight Technologies also manufactured the VLI 1 and VLI 2 for the SOPMOD M4 project. The VLI 2 was a cool light for its time. It had a very unique housing that allowed it to run three 123's or six AA's. Performance was about the same as a Surefire 9P.
