That looks nice..I knew my light had a actual draw of 660 watts emitters to close humm things I have to look out for. I still have grown a gram a watt with it at least but I know there is better equipment to be had. The optics lights are the actual draw so they use a full three watts per LED instead of close to half with the leds in my COB? Here is few plants that have grown under my cheap leds pretty impressive too. I can hardly wait to try a top bin light or lights to see what I can produce then PEACE BROTHER PS all autos and grown under 24/7 light regimeView attachment 508590 View attachment 508594 View attachment 508592View attachment 508593
The optics use 60watt vero18s at 1amp thru magnetic 60 degree lenses and 90watt vero29s at 2.1 amps thru 90degree magnetic lenses.
Yes with the COB spacing it would be hard to tell unless you are running multiple make fixtures.
90watt vero29 needs to be 10inches center square from the others. any closer than that and overlapping intensity will cause burn
What type area are u covering with 660watt?
