2 Pack LED Grow Light Panel 200W Lamp for Indoor Plants, Full Spectrum with White Blue Red UV IR LEDs for 4x4ft Coverage Grow Tent Greenhouse Veg and Bloom Seedlings Hydroponics

I can’t believe how perfect these lights are. Amazing growth and very little expense to operate. I use 18 hr on and 6 off every day with quality results. Best grow lights I have ever owned

I bought 10 of these primarily for an outdoor greenhouse, but have been using two of them over the past two months as an indoor grow light in a tall cardboard box once cucumbers and tomato plants got to be over 6 inches tall. I found a group pretty rapidly with this grow light within one to 2 feet above them, within a 1 1/2 ft.² foot print/box. As they grew to over 1 foot even when they got to be within 3 to 6 inches of the light it didn't seem to burn them. Cucumbers seem to love the intensity even when they get up real close, but my tomatoes seem to start getting some browning when they get that close. I like that of power cables have a switch makes it more convenient. You can tell that these are better quality power modules because they have separate power boxes on the back of each one. They are super bright no way you can look at them without burning your eyes. I'm hoping when I install them in my big greenhouse that the plants still like them enough from 2 feet away.

Generally the lights themselves do quite well. The only drawback is the suspension. It's a metal cable coming to each corner with a clip and you adjust the distance from the top to the light panel with a small metal ring that you crimp to hold it in place, doesn't make it very helpful if you need to adjust afterward. Would be better with some kind of drawstring or locking pulley system. I generally just take the wire suspension off in my setup and zip-tie the corners to the bottom of a metal storage rack for starting garden seedlings

Essential for any indoor/grow tent growers!! I got these for my plants and these changed the game for what I’m trying to accomplish! Durable and powerful UV lights, minimal heat radiating, plants vegetative growth responds immediately to the white and red UV pattern. For the affordable price, these lights jump started my plants vegetative growth in a matter of 2 days and still going strong. **Important to know to set these on a timer!** plants still need a dark period for growth. Recommended light time should be about 16 hours the lights are on : 8 hours lights are turned off. Varies on what you’re growing but would recommend having a timer so lights can turn on/off as scheduled required.

They're okay, I use them for lights over my seeding humidity domes. Too weak to provide real growth, I think.

Great product for the money. Easily assembled, very lightweight, durable, they stay cool, easily adjustable, with plenty of power cord. The lights themselves are awesome, my plants have responded very well to them. Will definitely purchase again when needed. #WorthTheMoney

We live in the Midwest and its to cold outside to get our garden starts going and ready to plant in the garden when it finally warms up. We don't have a good South facing window to use so these seem like the cheapest and best option. The starts seem to love the lights are are going very well. They are quiet, easy to use, and seems to be well made for as simple as they are. I have bought 2 more sets to use for plants. One question I have though are the 200 watt total between the 2 units or 200 watt each?

Shoulda known by the vague info on the product page that these were gonna be toy lights. If you are growing a couple succulents in 3 inch diameter 3 inch high containers, or a single head of lettuce, these might be worth your time and $46. Otherwise keep looking. The 200 watts it claims, is actually the LED to incandescent equivalency, I doubt it actually attains such lofty heights. My camping headlamp puts out more lumens than these panels do. Seriously. One of the reviews claimed to get a meter reading close to 2000 lumens - I politely suggest that person double check their meter is functioning properly because I doubt these lights are that strong. (remember bright to look at is very different from actually casting light that is bright when seen from the direction of the fixture , itself) The description also gives the impression you can switch settings to control which color LEDs are on, but that is not the case, it is simply all on or all off. The product page and package labeling claim there are IR LEDs in the panel, every LED is labelled "W", "B", "R", or "UV". Not a single one is labelled "IR", nor do any of the LEDs appear to be off when the unit is turned on (typical with IR lights since they are technically outside the visible light spectrum). Therefore I am left to presume that there are in fact no IR LEDs in the unit, which was one of the light spectrums I specifically wanted them to have. The lights are sold and described as being for gardens and perfect for grow tents, BUT they are not even IP65 rated , they are IP20 rated - that second number, the '0' - yeah, that means ZERO protection against moisture and water. So don't use these on any plants for which you use a mister, or foliar feeding system, nor in a room with a humidifier, and certainly not where you hose spray your plants. And that "2" number, stands for protection against solids. At a "2", you better hope you never kick up any dust or dirt - like when re-potting, or topping up soil for older plants. Why ? Because there is literally nothing protecting the LEDs from anything - even regular dust accumulation. Fortunately they do not draw much electrical power, because they are not grounded - so when they get wet, or LEDs start to fritz because dust got into the connections, you are at risk for getting shocked if you touch the unit while it is on. (REally , who thinks ungrounded electricity is a smart choice in the often wet environments of of garden spaces/rooms/tents? Are they small? at 1 foot square, yes, they are. They are also extremely thin and lightweight. All good qualities. The stated specific lightwave frequencies are also desirable - especially that 390nm UV-B light. They just are not powerful enough and the light fixtures are not actually made for, or suitable for the application for which they are being marketed. Maybe it's okay for countertop hydroponics. If that is what you need a light for, place these about 5-6 inches overhead and you might get good results. Otherwise, Just don't.
