Sil led heat sink and reflector for free

Ya, then there’s that whole UL approval process

I was looking on Etsy today and found a hard disk lamp somebody just made, cool ideas used in it like magnetic hinges for position holding the lamp with drive magnets of course

Using the sil8 I was able to read the output from 8” away: (using Korona and white paper filter)
Is that good enough for co2 richin?

Um, if that is accurate, anything over 1000 you should technically be enriching. It's generally advised for anyone not enriching to stay under 1000.

Ya, I thought so, I just need to raise the light and cover more area, it is blinding when close
