DIY COB LED Calculator

i can see that efficiancy=efficasy/322
why 322?

Can you do the same exel with vero 18?
I honestly couldn't tell you why the 322 value is used. I just used SupraSPL's spreadsheets for vero 29 V2s and changed some of the numbers. Hopefully someone can explain it a bit better.

do you have the link to the data sheet for the 18's?

I think 322 is the theoretical max output for leds or this particular cob in lumens. Now, where that number exactly comes from, I dont know :)
