I recently got an LOCw workign with olike casing and lm317 running at 381mA. It burns when focused. however a lot of light is scattered around the beam, like a flashlight. This is annoying went pointing of certain services that reflect the light because it's spread out a lot.
I can't tell well the light is coming from. the o like module is adjustable..
