Well, I spent the weekend drilling 376 holes with a drill press...and I can say it would be too soon if I had to drill more.
Here's a shot of the cluster LED holes...marked to show which LED goes where. I will be using the BJB solderless connectors as I just don't have the time to do that soldering.
The cluster of LED's is placed on a 4" U-channel with 2" sides...it's about 1/4" thick. The rest of the LED's are on 2" U-channel...about 1/8" thick.
I placed my order with cdiweb.com today for my 6 drivers...3 HLG-150h-48B's and 3 ELN-60-48D's. Both are 3 weeks out once ordered. I will be doing parallel strings on both the Cool whites and Royal blues.
Lastly I need to order my fuses, terminal blocks, wire and resistors and I should be good to finish of the LED build.
