FECiDADimmable LED Grow Light 24000 Lumen 260 Watt, 2024 Best 3x3 2x4 ft Grow Tent Light, UV-IR Included Full Spectrum Plant Growing Lamps with 1176PCS LEDs, Daisy Chian Function, Quiet Built-in Fan

So far so good. These are great lights. At about 16 inches or so i can get a Lux reading from my phone of about 40,000. They work really well and have a good spectrum. My seedlings seem to responding well so far. Easy setup and use. I like the variable brightness and the linkability too. These do not have software switches so you can control it easily with an external timer.

Big fan of these. Had seeds sprouting within the week of planting. The fan is great and my seeds have stayed nice and warm in my indoor grow house.It arrived quickly and well packaged. Love that they can be connected.We'll worth the price!

These are great. They daisy chain together really easily. They are perfect to start seedlings.

This grow light is great but has one major flaw. In the photos you could see the outlet that connects light to light. But the connection is not US and the plug keeps falling out. If the company could send an adapter for this it would be perfect. I had to contact Amazon about it because I wanted to connect this light to others. I asked them to try to contact the vendor for support but Amazon could not reach them. Amazon is sending me a new light and I imagine that I’m going to have the same problem since the Amazon representative cannot see the type of connection that I need to make. I would go buy one but I don’t even know what type of connection it needs to stay in the light. Otherwise, I have to say there is no light as good as this one on the market for this price point. It has a built-in fan and adjustable light. The instructions are clear. The cables they send with this light are the best. I cannot see how people have ever complained about these lights breaking because the packing is so good. If you want to put this light on a surge suppressor or timer it would probably be best on a surge suppressor because the cable is very thick which is a very good thing to prevent fires, but I just can’t see it working that well with the timer. This unit burns cool but is extremely bright. An additional fan in the room would still be a good idea. I am growing herbs and I put it 16 inches above the head of the top of the herb and turn it at about 40% to 60% and leave it on about 12-14 hours a day. My herbs are on the west facing window and the light does not burn the plants but moisture level needs to be checked frequently and plants misted because they do dry out a bit more quickly. If you think that the light doesn’t work I would check my soil because it needs a soil mixed with perlite and moss or a low density potting mix NOT POTTING SOIl- but POTTING MIX! If you are the vendor of these lights please send me connectors that will work so I can link them together but Amazon is sending me a replacement this week and wants me to return the other one to you.

I want to preface this by saying this is by far the most powerful light of its size, normally you should expect to pay 1$ per watt or more, and the light does work. However, I worked at a Grow & UV-C light manufacturer for 3+ years and I feel compelled to share a summary of my findings (using this with legal herbs like mint).1. Wear eye protection or get a timer. I guarantee you this light could cause blindness just from repeated indirect exposure of 10 minutes per day at 20% brightneas.2. It stays ice cold even after being on for hours. It uses a low voltage fan almost like an old halogen light. The LEDs will last but I know the fan will go out at some point based on how it sounds out of the box. Again, at this price point consider this a disposable light and it is still a great deal.3. The light is too bright. You can get around this by using it for shorter periods than 8 hours. For seedlings even 20% brightness for 4 hours may be too much. They will perk up immediately and then be overwhelmed when you check layer. However I think it would be perfect if it was used during the flowering phase of certain herbs, moreso than any light I'm familiar with from grow stores.The light is too strong. The fact that is incorporates UVC and IR is cutting edge. However, in order for them to be effective you need to be able to disable them and use at the appropriate time. IR helps a lot to create denser (not fluffy) flowers, but is useless early on. The bigger problem is the short wavelength blue light (UVC). Think of this as steroids for plants. Normally the earth's atmosphere blocks most of the high energy light from reaching us, and the less harmful waves like A&B are more present. You can add this back in and jump start the photomorphogenic response, which causes a plant to beef itself up in self defense. This will cause a plant in late vegetation and flowering stages to create more resin, terpenes, and cannabanoids. But earlier than that it can stunt plant growth, especially in seedlings, and it is dangerous for eyes.If I were to fix this light I would improve the fan so it didn't rattle, add a switch to toggle IR & UVC, make the daisy-chain ports tighter, and potentially even reduce the number of chips or chip density.All in all, this is the best light on the market period for late veg and flowering, and probably fruiting vegetables, but is not suitable for sprouts, seedlings, small herbs, things of that nature.Theoretically you should be able to dim the light and raise it, but I think the light spill is already too dangerous especially for younger eyes like pets and small children. I would only recommend this light be used inside a tent, on a timer, and adjusted wearing UV glasses.I would also suggest there be more warnings, because I know for a fact you could create cataracts in a week if that was your objective.

The media could not be loaded. I have gone through quite a few different lights,teting out to see which one's work best for my plants since carnivorous plants need a lot of light .there was a lot of trial and error on my part and I finally caved in and spent over fifty dollars on a light which ended up being this one. I have been using it since January and my plants seem to be thriving . For the specs,I love how you can set the brightness. I have it set at about 70% with my plants, but it can definitely be a little blinding. The lower setting is still bright but not as intense.The fan is very quiet and it seems to keep the light cool. I run it for about fourteen hours and there hasn't been any issues with it becoming hot. There is before & after photos of my pings that have been grown under these lights in and they have gotten so much bigger while under this light., just in the last 2.5 months. Of course it also is how they're taken care of but light is also key!I think this is a great,more affordable option compared to some of the other fancy lights out there that cost double the amount of this one. If you are looking for a decent ,well working light that is adjustable with a fan, then I would definitely recommend this one.
