Could you post link to that calculator? I only found "older one".
The calculator is by @bggrass and the link is in his signature in post #176 of this thread https://www.rollitup.org/t/diy-cob-led-calculator.890214/page-9#post-12888124
Hey nevergoodenuf,View attachment 3904966 View attachment 3904984 View attachment 3904986 I had a feeling I couldn't get 1000w. I think the newer CLU058's are drawing less voltage, so less power. Either way I am pull 950w at the wall and a couple watts more when the fans are plugged in. I still haven't figured out how to upload the FLIR pics (not even to my computer), but I didn't see over 90* @ 237w.
At 30", I have a 140,000+ lux over a 40"x 12"+ area without any reflectors yet.
At 20", I have 200,000 lux over a similar area.
@Randomblame So 20,000 lux is 970 ppf. I never payed enough attention to this hand me down meter. I used it at to get an idea about what larger growers ran at canopy directly under the light. 200 is was the average over everywhere I checked, so I took it to Starlite to have my light checked at 200. The plant at the fixture didn't care that it was seeing 600 on that meter (2 @ 250w). Even Starlite made that mistake then, along with PPF, not PPFD. Every time I thought I was getting light burn, it ended up being the start of a Mag def.View attachment 3909033 View attachment 3909039
How are my reading looking now?But down worry about it 20.000lx is still an impressive readings considering the distance
Look up how to run .jar (java) files on your OS version, you may need to update JAVA or allow permissions to run it.
Older calculator works.Look up how to run .jar (java) files on your OS version, you may need to update JAVA or allow permissions to run it.
The object is to get the new one to work. I had to update something but was totally wasted when I did it and cannot remember what I didOlder calculator works.
