KOSCHEAL KS1200 LED Grow Light Full Spectrum Plant Grow Light with Veg Bloom Switch for Hydroponic Indoor Plants

I am extremely happy with this light for what I paid for it. I see so many reviews nitpicking small little things with this light. Can you buy a better light? Yes. But remember, this light is only $100. I challenge anyone that finds a better light on Amazon for the same price. Light output is enough to make it seem you are looking near the sun. Fans could be quieter, but, the air output is high. This makes the sound explainable. Made well. Sturdy Has weight to it. The adjustable line is also a plus, although, most lights do come with this. I recommend this for a small 4 plant grow in a tent or an another appropriate setting. If I did have a complaint, it would be about the cord size. I wish it would have came with at least a 6 foot cord. Preferably 8'. UPDATE (HARVEST RESULTS): Used this light throughout the entire grow. Last grow I had a weaker, smaller light and had good results but could tell it could have been better. I suspected it was due to insufficient lighting. I was correct. Same set up but now with this light. The final resulted in a 4.8 THCA gain. Again, I high recommend this light for a small 4 maybe 5 plant grow in a 4'x3' tent. Read more

New to using modern LED grow lights. Retired EE and I read someone else's review mentioning lack of safety should electronics fail (fire hazard). I agree. These have no UL, CE or CSA or any other regulatory certification claims anywhere inside or outside of the product - so I've ordered thermal cutout switches and will also add some 2A inline fuses. Total investment about $40 for two of these beautiful grow lights, and about 5 hours of my time - but worth it for peace of mind. My dragon fruit 'nursery' is right next to my house. Otherwise, solidly built, nice powder coated steel chassis all around, fans are quiet, and I can't look at the light without sunglasses, very bright. I've also ordered a PAR light meter, but estimate that these (the KS1200) throw out about 300-350 umol/m2/S for each of the two that I'm installing. I'm satisfied, would recommend for light and quality of build, but I also wish the maker had added thermal safety features (you know the fans are required for cooling the power supply inside, and I've seen fans die many times. To set my vinyl fence, grow tent or house on fire when unattended is just too much risk for me, personally). Read more

I am writing in case others are having the same problem I have. I am getting red/maroon leaves in ALL of my seedlings this year, which is the first year I am using these LED lights. It looks like I have the lights too close to the seedlings, which other than the red leaves are doing great. In doing a search online it looks like I should have the LED lights at a much higher distance (12+ in) than I did for my old T5 light system (3-6 in). So I raised the lights and will return if this does not do the trick. I also confirmed that I did not have the bloom/flower switch turned on (which apparently produces even greater light intensity). Other than this issue, I have had a problem with the light plugs being sensitive and if I bump the lights they sometimes turn off even though plugged in. I wiggle the plug and it turns back on. I have 2 daisy chained together. But other than these issues I think these are great lights for the price. Read more

While I do not use these lights to grow cannabis (I wish!) I bought these to help some young trees brought into my house during freezing weather. I also use this for some tomato, cucumber and other food plants. I cannot believe how my cherry tree reacts to this light. It’s absolutely incredible. I get blossoms all over the tree when I have it inside with this light. I put it back outside when it’s warmer and it basically stops. My tomatoes also grow insanely fast and huge with these lights. The difference is so significant that I’ve decided to turn a corner of the house into an indoor garden. The different light modes absolutely help with the particular needs of the plants I’m growing. Can’t recommend these enough!! Read more

I'm not really sure.... I didn't like the spectrum for veg. Plants weren't responding but just went through a transplant. Most of what I have read is LED is best for flower and MH still rules for veg. I did not like the hanging set up... for a skinny LED, you still hang 14" from the hook and they only provide one daisy chain that allows the light to spin and move. I added a daisy and spread them wide to get max height available and keeping the light in a fixed position. Read more
