CXhome LED Plant Grow Light Strips Full Spectrum for Indoor Plants with Auto ON/Off Timer, 560 LEDs / 8 Dimmable Levels, Sunlike Grow Lamp for Hydroponics Succulent, 8 Pack

Bought 3 units that I installed to replace a 4 ft double fluorescent plant fixture.I had bought a red and blue led plants light before that gave great results but, for houseplants, it was no joy to watch them. Plants under the red-blue leds looked brownish-redish, could not tell if the soil was dry or appreaciate leaves or flowers coloration.These being white leds, plants leaves and flowers look the color they should under it.I spaced the units evenly to cover as much as possible to the 4 ft lenght of the fluorescent.To minimize the darker space between the panels, I installed the 3 panels in a row rotated as diamond instead of square so that they point toward one another, almost touching. That way there is less space without leds above the plants.Panels are from 10 to 15 inches above top of the plants, depending on various heights of the plants, and are on a timer for 15hrs on / 9 hrs off daily. Light is very bright and plants are growing normally under it, keeping compact which means they do get enough light.Since I can't get raise the leds panels, they are in an open cabinet that was made for the fluorescent fixture, I may reduce the lenght of on time as there is a film of green algea growing on the soil of some of the plants, mostly the cuttings in a mini greenhouse where humidity is kept high.I measured the luminosity at 10 inches at around 19000 lux and around 30000 lux at 6 inches. The light meter I used does not give par, only lux and foot candles and is not meant to be used with colored (red and blue) leds but since these are white leds, it should give a relatively accurate reading of the luminosity that these panels produce.I also measured the electricity used by these panels. This was unclear in the description of the units but using a power meter, the electricity usage for one unit is 28.5 watts. 75 watts in description must be a perceived light equivalent.Given the lux count and plants reaction, I'm happy these are not using 75 watts each. At 28.5 watts, it is almost a third of the 75 watts stated in the description, so quite inexpensive to run.Still, though the power usage is low, the drive that powers the unit gets surprisingly hot. To lessen the heat of the driver, I suspended mine in mid-air.The top of the led panels gets barely warm if there is enough space above it for sufficient air circulation (I'd say at least a couple of inches).All in all, I'm happy with these lights. They are inexpensive, do not use much electricity and, most importantly, plants are doing fine under them.

This has been very helpful for my plants. The light is more like daylight than the yellow projections you sometimes see illustrated for full spectrum lights. It can be a little bright so make sure to keep it in an area where that won't be a problem while it's on. Read instructions carefully on height from plants and duration of use (not to exceed 18hrs per day I think? I just have mine on a 12 hour timer: 0800-2000) This can put out a bit of heat so be careful of putting things over it, give it plenty of space and whatnot and watch where the power supply is located as it can warm up too. I haven't experienced any dangerous temps but it can be a risk with these things. The only thing I wish were a little different was the power cord length. It's a little short. I just ran a power strip to it and it was enough of an extra spacer.

Love this for my ikea greenhouse cabinet set-up! I attached this to the ceiling of the cabinet of my tall fabrikor and it provides great light for the whole cabinet. My plants love this light and has produced several leaves as a result. I was worried about it burning the leaves of my plants when it got too close to the light, but guess what? It didn't burn!. Instead, my magnificum really loves it! I highly recommend this product +

Seemed like it was a returned light as I received one with part of the cord already put together and then the part of cord with the 'electric' box and plug in end of cord missing. I didnt bother returning it because I had an extra cord.

When I first saw 300W in the name I thought this would be a bright light. It is not. In my mind I was comparing it to the bright pink 300W with noisy fan light it replaced. It is however a great light for starting seeds and small plants that don't need a tremendous light.It is fanless, easily mounted, and works well. The spectrum is easy on the eyes and is great for indoor plants that share space with people. Only using it for a short time so far I can't comment on how long it lasts. For the price it sells for it is worth it.

I am a seasoned grower. I purchased several of these to replace my CFL growing system. I get twice the brightness at 1/3 the power. I have 2 of these lights per shelf (3 shelves) in a 22 1/2" x 14" x 6' grow cabinet. I run a perpetual grow. I train my plants, bending the main branch down, allowing all the branches to grow at the same height. I place a wire mesh screen on a frame over the plant and train the branches to fill in the screen. During the bloom stage I let all the branches grow upward at the same time. This keeps all the flower tops between 2" and 5" tall. Placing these lights 2" from the tallest flower tops, they will get over 50,000 lux (750 PPFD). This is more than sufficient for this hobby grower. You must have good air flow between the lights and the tops in order to do this. I am averaging 3 oz. a month. This is more than enough for me and my honey. Happy Growing!

In the ad listing and description this light is claimed to be 75W in numerous places. This is absolutely FALSE!The led driver output is maximum of 40V DC at 600 milliamps. Photo of driver included. That is 24 watts maximum no matter how you do the math. That means regardless of the led efficiency the light can NEVER reach more than 24 watts of energy consumption.8-2-2019----Driver died after only approx 6 hours of use. Sending back to Amazon to see if I get the same false claim product as a replacement.
