my suggestion to you sir would be to stick to the tried and true cxb 3590 3500k ,then toss in a few 3000k . Then make the spectrum complete with star boards, far red ,photo red , and royal blue. and you will beat out anything.
Also these are DIY so we use drills and bits ,and stuff like that, not drill presses and water jets. you are speaking engineer, I am speaking just get it done. but again no problem they are great and I will continue to buy from cutter.
that's correct M 3.5 as I said same as face but longer. don't get me wrong I like them. But one turn to much and it stripped right out. Think about it thin little screws in soft aluminum.
actually not harsh at all no disrespect! I use the screws that are speced out. if you built a light with the cutter heat sinks than you absolutely know that the side screws really don't work out. I really didn't want to bore out a threaded two holes per side of each heatsink then go back and buy...
I say we make the spectrum one chip one color one Cobb at a time. I have 22 Cobbs CXB3590 and almost 100 far red 3watt Cree chips that will cut up any spec chart you can throw at me. I call it once apon a Cobb my friends.
that was the first Cobb. which was 4/ 4' bars with 3 cobbs each. Along with two HLG- 320- 1400MA. Just added four more 4' 36 far red Cree chips on each bar.
