And yes, I can hear all the comments already, what a dummie I am, as I could have purchased a truck load of high end Cree products for what I spent with stellernet. There is a story too long to tell, maybe later. With the spectrometer tests I am interested in seeing if the cheap cn cob led match any of the spectrums of the most popular HID ie, Hortilux 1000 HPS and the SolisTek 1000k. I live in Denver and commercial growers all use the Hortilux or Plantmax exclusively. I am attempting to find off the shelf products that can compete.
Happy, thanks for the comment. The COB LEDs are the cheap Chinese, Ebay items. How do you check, verify the color? I have been importing other hydro items from China for years and know that specs need to be double/triple checked. I do have a stellernet spectrometer that reads 200-1200nm. I have tested the 3000k and the spectrum "looks" great when compared to the chlorophyll absorption spectrum graphs. I intend to get all the cheap 100w ebay cob leds that I can get my hands on and test them all.Cool design... Are those cobs you have there, Chinese? They look like the ones I used to use for my business. If they are, you might want to check if they have the right color. I thought mine were 5000K (i bought them as 5000K) but at a qualitytest it appeared they were 7000K. Chinese quality, they said that it was normal. No Chinese leds for me anymore.
