I found 100W white LED lamps in the 4000k spectrum at Super Bright LEDs.com I paid $80.00 each, the price just came down to $72.00, I know because I just bought a 3rd lamp. Each one produces 12,000 lumens, I have the lights about 25” apart. Am growing 4 blueberry under the two lamps. I top and...

Indeed. Thanks for your input Future Grower.

I agree that these are not the most efficient LEDs compared to the new Cree COBs. But I just don’t care to do it as a DIY project, and for $160 I got what I needed

Ok- I am talking about effective lumens, not total. 200W of the white light LED is producing 24,000 lumens, but there is no heat, so the plant canopy can be much closer to the light source. HPS lights (all light sources) are measured at 12” from the bulb. Most folks are probably keeping their...

Thanks- no burbles, this is a “white light” LED lamp in the 4000K spectrum. Best of all this bud was way more potent than the last plant I grew. More blue spectrum makes for more THC and other terpenoid production

I don’t know for sure yet. These are white LEDs in the 4000K spectrum. Actually I will create some controversy by saying these new low cost LED bulbs are superior. I say that because I have total consensus from four people besides myself that this batch is holy shit more potent than the last...

No no need to go to 600 watts of LED. Here’s the math: suppose the 1000W HPS is producing 100,000 lumens 12” away form the bulb, well you can’t have your plant canopy that close, you will burn your precious buds. So at 24” from the bulb the lumens will drop to 25,000. The two LED lights I am...

I recently purchased two 100W LED lights from Super Brights LEDs online for my flowering tent. They are in the 4000K range. They output 12,000 lumens each, they cost me $80.00 each; I just harvested my first plant, a Blueberry. Previously I was using a 400W magnetic induction florescent light...

Toaster - thank you for the suggestion on the Meanwell driver, I will check it out. I re-posted the pictures as jpegs. The entire housing acts as a heat sink. I misspoke, it's actually a channel - not a pocket. The photo shows an extrusion with black anodize, but we have a lot of this stock...

Howdy all. I signed up for this website today, compliments of a Google search for Cree LED module grow lights. Have a small grow for several years now (legal in MI), and due to odor control issues have been trying somewhat unique lights requiring no AC. Currently running a 400W magnetic...
