Constant 6" exhaust, growing during winter here, so ambient temps not too much to contend with. Range for tent is 70-82 degrees F, only running 600 watts, so 50/per cob also helps, you can drive them to 100 watts each, but that imho gets wasted and passed off as heat...
Dan I was just trying to avoid doing something wrong in another guys thread, that's why I messaged you. Was trying to be polite. This led thing is a learning process for me. Thankyou for explaining this to me.
If considered your coverage area, LEDs needs more heights to cover more area. Small sized LED boards could be kept at a distance of around 18” during buds first phase while it’s recommended to keep it at least 25 to 30” during plants flowering phase.
I think It also depends on the LED's capability of delivering a specific level of PPFD measures. Too high LED will scatter light and will result into loss of light which won't give any visible good results.
