1800W COB LED Grow Light Full Spectrum LED Plant Grow Lights for Indoor Plants Hydroponics, Vegetables, Seedlings, Flowers,with ON/Off Switch and Dasiy Chain

So I received the first batch of these COB LED grow lights ("1800 watt" version... 300watt actual LED power) and have to say that they look more than capable of performing their function (i.e. providing plants with a suitable energy source). I haven't had the pleasure of growing anything under them yet but I can share a couple of first impressions.1) Don't let anyone fool you, plants eat light, light is measured in several different ways but the most popular are PAR and Lumens. LED grow lights are not magical. They cannot provide a plant with "better" or "more efficient" watts. It's true that LED lights can focus on certain wavelengths favored by plants, but you still have to ensure that you're pumping out enough of them to feed the plant. I guess that what I'm trying to say is that 1,000 watts ran through an HPS or a LED setup will pretty much produce the same results. The big difference being that with LEDs running inherently cooler than HPS/MH, you can place the light source much closer to your plants, thereby increasing the PAR reading or Lumens reaching each plant. I'm covering 2'x2' with each of these and it looks like, from experience, 4 of these will equal an overclocked 1k watt HPS setup (1,250 watts at the wall in both setups).2) These lights are cool vs HPS but not nearly as cool as other LEDs out there. It may be due to the COB LED setup but these lights run significantly hotter than other LEDs I've seen. It's not like they'll increase your room/tent temps by 25 degrees like HPS but they will increase it by what I would estimate to be 5-10 degrees. With temperature being a key growing variable, I thought this is worth mentioning.3) The lights have no cover. The COB LEDs are completely exposed. This may be a pro for those who want nothing to interfere with the lights and a con for those who require at least a certain level of "weatherproof-ness".4) The advertised daisy-chaining feature does work up to 4 lights (confirmed) but the cables that come with the lights heat up excessively in this configuration (especially for the first light in the series). I'm not entirely sure if this can be solved with better cabling or if it's completely fine to run the setup despite the cable temps but I'm certainly not going to mess around with this.5) The included mounting hardware is fine but you'll want to beef it up eventually. I did setup all of the lights with the included hardware but am currently looking for ways to upgrade it. The included gear feels capable of doing its job but flimsy enough that I won't trust it long-term.In conclusion, these lights appear to perform exactly as advertised. They chew through 300w each to pump out some pretty strong full spectrum coverage for your plants. I have yet to see the results of cultivating with them or their reliability long-term. That being said, these are $120 lights. You get an insane amount of output (PAR or Lumen) for the price but keep in mind that you're buying mass produced crap out of China. I completely expect to have one or two of these give out on me but, to be honest, at $120 each, I don't care. I can easily replace one if necessary vs $1,000+ products where you're SOL.TL;DR Cheap, more than capable lights for the money.

This seems to be a rather well-built product. I am using it for cannabis cultivation. From the start, this is powerful, this is like the sun light. As with any product of quality, I would recommend you consider the weight of this and how you’re going to distribute it and hang it above your prized positions. I should’ve taken my plant out for just five minutes.Update: This light gets warm, and you need a humidifier to adjust the humidity. Great light, I like and trust this light.Updated update... I turned the fan up to full speed and temp and humidity balanced itself, forget the humidifier, it's bad for my carbon filter.Update: Great harvest, this is awesome and price is awesome. I would recommend paying attention to the rise in heat you would get in a enclosed tent situation. Small changes sometimes have big results, I’m just having problems getting my Growtent below 80 degrees in the daytime. Probably set around 81 to 82° on a regular basis and this seems to be an environment for things in my tent I don’t want to be in my tent. I’d like to be in the low 70° range and my plants seem to thrive. Maybe I will add CO2 to the chance to add some heat resistance.

The light came with one cob out. I sent a picture and email to the company and I had a new one within a week. This was during a holiday week! Love the light and will but again!

plants love this intense light. I have accelerated growth and exceeded plant height and weight predictions as a result of these lights. they work really good for me and my indoor garden

The plants love it!! There’s warmth from the lights but the housing is kept nice and cool by the fans inside. Nothing rattles inside and it seems to be very well made. The only downside is that it was shipped with zero paperwork/information about the product or warranty but this isn’t a dealbreaker given the price

Very strong. About 4 of these to get 1000w hps power, but runs cheaper and cooler. Pays for itself

My plants love it better than other LED's but they put out more heat

Very bright.seems plants are so healthy.Iove this light so will get one more for growing room. :)
