A lot of us have seen the strange yellow rectangle on blue rays, I had one amongst my last GB sleds, it was one of 2 unmarked holders....this thread

I decided it was useless for any of my pointers so put it aside...tonight I had a play with it and discovered it has a sweet spot at 80ma where it suddenly brightens dramatically with no sign of the yellow. It levels off almost immediately so I have not taken it any higher.
It burns electrical tape and melts the wax on a red match....not quite lighting it ( this match has been knocking around on my work bench all winter, I will try a fresh-sharpied one tomorrow )
I discovered something else tonight as well. I had it shining out of the workshop and as I was moving it in the clamp I saw red.... When I shine it, obliquely on a dark green leaf, potato leaves seemed about the best, the dot is distinctly red when viewed from the laser but no sign of red when veiwed looking toward the laser.....I tried to photograph the effect but my camera wouldn't pick it up.
