Default 2nd build ever made after a red with am osram 1.6w rated

im still new to the forum and started alitle crazy about the whole thing,i have already made a classic red cutom build out of a dvdrw(i already have read all the topics on red diodes 0.0) and next i wanted to make something more powerfull so i ended with a a pair of 445nm 5.6 osram diodes and safety glasses.i bought 2 diodes because it was a good deal also i was pretty sure as my 1st blue build something could go wrong and fry the diode so a backup should be good the project is almost finished and working great with the driver set to 1.5A,batteries are draining alitle fast and lower the A but thats fine.the host is an old classic flashlight that had 2 D batteries(now im using 2 18650s)i used a heatsink also and a custom ring on the from for an easy focus,the lense is a g3 445nm,also the i used a plastic on the power button for safety reasons and now the button is inside of the plastic and its safer to have in i a bag etc.the duty cycles are big with this heatsink and im still excited to my 1st build the last thing i want to do is a cover on the front where the glue is. photos incuded also and the beam is on clear air room no smoke or something else

Congrats on your first build! Have fun and stay safe!

Also - maybe don't point that at your TV ... might end up damaging it with that much power.

Find a brick or the back side of a bathroom tile and paint it flat black. Those you should easily find laying around. Not the TV "pethaky moo"

Yep - brick, ceramic, concrete, all good choices.

I often use black anodized aluminum heatsinks - especially heatsinks with big fins on them, helps contain the diffuse reflections a little.

For a while I was using the side of an old PC - Case was metal and black, either powder coating or some real thick paint ... not sure - didn't melt, don't care.

Could always build a "proper" beam dump for cheap.
