KOSCHEAL KS1200 LED Plant Grow Light Full Spectrum Daisy Chain with LM301B Veg Bloom Double Switch for Indoor Plant Seedling Flower and Fruiting to Provide Suitable Spectrum Quiet Built-in Fan 130W±5%

Don't listen to the negative reviews, this light is beyond what it's worth! I was a little sceptical at first reading some reviews but having run one since may without any single issues I can openly say this grow light is perfect. My tomatoes are looking absolutely fantastic and it's all thanks to how powerful the LED's are on this light and the plus side to that is it costs pennies to run, it's not even noticeable on my electricity bill! Works as intended, One Veg and One bloom switch for light settings and you can run both at once if you wish, the vents push out hot air nicely keeping the unit from overheating but at the time not scorching the tent it sits in, normally it sits about 23c in my small tent with just the one unit both veg and bloom light on. In short for something so well built and simple to put together straight out the box for this price is a no brainer! I'll be grabbing a second in the near future!

First off, lets bust some myths being touted here... 1. It is a 2000w EQUIVALENT lamp - meaning by using its 200 odd watts, it is producing the same amount of light as standard bulb drawing 2000 watts (which for those lamps means that 1800 watts of heat is being pumped out - so its more of a heater than a light, whereas this is a light). When an HPS light goes out, the temperature in a grow tent will plummet, due to the loss of all that heat. An HPS by the way is more efficient than a standard bulb but only by a few percentage points, so still the majortity of your electricity is being radiated as heat not light. 2. As far as your plant is concerned it is FULL spectrum - it provides all the useable light the plant needs, the stuff a plant cant use in 'daylight' goes to waste - this type of light is not wasteful in that respect. When you look at the leaves under the light, they appear black, because all of the light falling on them is being 'absorbed'. 3. The important thing about light intensity is lumens - this is not quite the 24000 of full sunlight, but its a lot better than most bulbs and importantly its all in the spectrum areas plants require for photosynthesis, so no wastage. So no one here is lying about ratings or wattage or anything to do with the equivalency of the light - it is just that EQUIVALENT. So I am using this to light an area 120 x 60 and it is providing 'daylight' light levels equivalent to the midsummer in the tropics over that area. My seedlings react by growing exactly as they would in the wild, sturdily and quickly. I have chillis up in 4 days, cactus in 3 and some succulents inside 36 hours - none are showing stress, none are getting 'leggy'. No sure if I will use it to grow a crop to maturity, though I feel sure it would easily do this, but for me this is more to do with available space and the fact that I will grow stuff on in a conventional greenhouse afterwards. This allows me to start early for long season crops in a dark garage with little more than this light, a grow tent and some bottom heat. So for its cost (about the same as an HPS with a ballast and gear) it is using 20% of the electricty - requires none of the ventilation (which just blows out the heat into a cold void, rather than being able to seal it in with the plants and lights up and extinguishes instantly on my timer. All in all excellent value for the price. 31 Jan 2024 - I now have 5 of these lights - the original 2000w variant used in the germination tent and another 4 x 1200w lights, daisy chained in a larger growing on tent. All are on timers, providing 14 on and 10 off or 16 on and 8 off. Again Chillis are up inside a week and growing away well. Tomatoes the same and all of my cacti sowings are showing no signs of stress.

After a couple of months use it work just like it says it does would buy another one but i am worried to order off Amazon due to the way they handle parcels if this company has a way to order straight from them I would prefer to do that

For a 1x1x2 is excellent 👌

Have 1 already and works great so I purchased another

Gave the lamps 5 stars even though the developed faults after 6 months. The fault being that a 1/4 of blue lamps in the same quadrant failed to illuminate on both lamps. Up to that point they had produced an excellent crop with no hassle at all and for that reason I would have given them a five star rating on that alone. It may have been a coincidence that both lamps produced an identical fault or it may have been down to a component failure in the driver circuitry but you can’t always blame the manufacturer. It could be down to it being a bad batch of devices that a sub-contractor has supplied. The fact that kocheal offer a 3 year warranty makes me believe it was probably the latter. Having contacted the company through amazon and advising them of my problem, the customer service representative could not have been more helpful, and I received 2 off replacement lamps. The timescale between reporting the problem and replacement lamps arriving was Wednesday evening to Tuesday the following week. If the star rating was any higher I would have no hesitation in selecting it due the prompt customer service (from Sean). Thanks

Been running a set up with different LED lights, but bought this as I wanted a full spectrum grow light. I swapped the lights out today and it trips my Arc Fault Detection Device in my Consumer Unit. Nothing else has changed - only this light. The AFDD has been fine since it was fitted a few weeks ago, but within a couple of hours of switching this light on the circuit went, reset it and within half an hour it tripped again. I’m an electrician, so I replaced it with the original RCBO, but it doesn’t fill you with confidence. What it’s like as a grow light is yet to be discovered, but it shouldn’t trip like this.

I bought this for growing Lithops seedlings through the winter months. As they are in 5cm pots it will cover a lot of pots. I am very pleased with it although I have only had it for 1 week so too early to say if the plants like it. It would have been helpful if there had been a bit more advice & information on the recommended height above plants. Obviously the higher it is the larger area it will cover but the light intensity will decrease. There is no information to advise on this so I guess it will just be trial & error. Packaging was excellent as was delivery time. Very easy to install in minutes provided you have something to hang it from. If teamed with a time switch it looks after it self. There is a slight sound from the fans but as mine is in a greenhouse that is no problem.
