    Hanging it presented a challenge as the small clips easily bend under the weight of this massive light
  

*by R***Y on Reviewed in the United States on March 2, 2018*

I almost gave this four stars, but that’s really just my fault. My first impression of the 2300 version was pure astonishment of its size. Hanging it presented a challenge as the small clips easily bend under the weight of this massive light, and the eye holes are too small for the rope hangers I have. I rigged something that I’m reasonably certain will work for now, but I’m thinking thick gauge stripped wire would be best.That’s the downside.....everything from there seems to be upside. Four switches to control the intensity of the veg and bloom spectrum. It also seems very bright with a huge footprint. I’d highly recommend this light to someone who is aware of its size and weight.....Update: three days of use and one of the cobs died. Lowering my scoreUpdate: the company doesn’t have a website or any contact information. Don’t buy from this random nobody......it won’t last and your money will be wasted

    So excited
  

*by M***  on Reviewed in the United States on November 12, 2017*

Literally got it today and I must say I'm impressed with the craftsmanship of this product quality through and through. Turned it on to see led ...boy it's totally more noticeable than the three current leds I have combined it's a no brainier to deduce my return will be substantial but I'll probably provide a update after I use this product but so far this product looks like a heavyweight contender...

    Noticed my plants canopy getting unusually hot, then noticed ...
  

*by J***C on Reviewed in the United States on January 28, 2018*

Noticed my plants canopy getting unusually hot, then noticed the fans are blowing down on the plants, unsure if this is a design flaw or manufacturing problem, but it makes the light unusable as is, I'll have to see if I can reverse the wires to the fans, or maybe flip them, in any event not to impressed with it.Update:Once I reversed the fans the temperature dropped from 95 degrees to 75 degrees at the canopy, I'd be interested to know if others noticed that the fans are blowing the hot air down on the canopy, or if my was manufactured incorrectly. It was only a 5 minute job to reverse them and it made all the difference.Update #2Tested the light aginst a (1000) HPS same strain same nutrients save everything except lights;LED: 675/Watts 400 Gms./cubic meter squared, Buds, light airer, and smallHPS: 1000/Watts750 Gms./cubis meter squared, Buds, tight, hard, and largeThats a 15% better yield of more desirable bud than the Led, although the Led 's have come a long way they still can't beat the HPS.I know give this light 3 Stars, but if in the market buy a HPS
