You could always reuse the 4000k and 5000k for a veg lamp if it turns out to hinder flowering.I have (2) 3k ab's (1) 4k and (1) 5k but I can't remember off hand what bin they are. I built this light in attempt to have a multi stage light for flower and veg, but also as an experiment to see how the different spectrum may be of any benefit or not. I plan on buying more ab 3k's later on and will most likely replace the 4k and 5k.
Thanks man! The sinks are cool to the touch.Nice work lmpt! Is that a 3000K for flowering?
CH, love the lamp! What kind of heatsink temps are you getting?
I just checked the temps using the temp probe that came with my multimeter. Ambient temperature was about 24C. First I pressed it into the notch next to the LES, which got as high as 70C. Then I pressed the probe against the base of the heatsink right next to one of the cobs, and it got to 35C. I'm guessing Tj is around 80 or 90C, or is that notch a good indication of Tj already?
