Default Review on my 80-100mw 450nm pen build

Hello and welcome to my thread with pictures I took
A jayrob leadlight and a techhood 80mw osram 450nm. I took the heatsinking from a broken ebay laser and super glued it on. The laser runs on 2x 10440s. Before I put the heatsink on the duty cycle was 20sec on/1min off, and with the heat sink 1min on/ 1min off
it's a darker blue in person. ALWAYS WEAR SAFETY GLASSES haha unless I'm outside or pointing across my room, it's pretty big (longer than 30 feet).
in fog with the lights on
in fog with the lights off ( I put in some eye candy for ya there)
Any way as a random question, does 405/450nm,dot look like there's a jagged circle of light around it from farish away?

Nice build! Never have seen 450nm, but I expect the color to be almost identical to 445nm?

+1

According to this tool: Wavelength to RGB / HEX Calculator

450nm is almost identical to 445nm but instead appears a little less "blue"
