Very very very good light. Has an app you can control and add presets on, the timing function is super convenient. Super easy to install, plenty of power and sits in a green tent with high humidity so seems pretty water resistant. Love how sleek it looks and the color tbh, worth it!!

I've tried a bunch of different grow lights since I've started growing! After finding and using one of these for a full run, this is now my second G1500!! Absolutely LOVE these lights!! Bluetooth and Wi-Fi!! Works amazingly with the Spider Farmer App!! Im running one of these in my 2x2.6 Gorilla grow tent!! I had to get another for my Spider Farmer 2.3x2.3! These lights put out very little heat!! Super easy to put together outta the box!! Super bright!! Absolutely no complaints!! Thanks Spider Farmer!!

This is the third full-spectrum grow light I've purchased for my orchids. Though it coast more than my other grow-lights, it has been worth the extra coast. For one thing, the length matches the length of my tables so I don't have as much light drop-off as I do with my shorter grow-light panels. The second feature that I'm thankful for is the ability to adjust the light intensity in discreet increments, unlike many other lights where you only have options of 0-25%-50%-75%-100%. It was worth the extra for this feature, making it easier to fine-tune the light intensity. Spider Farmer's build quality has been excellent on the two lights I've purchased from them. I'm seriously considering replacing my smaller light panels with Spider Farmer G4500 units.

My first time buying a Spider Farmer grow light and I am impressed! I decided on it because of Spider Farmer's excellent reputation and it was on sale for a great price. I am using it in a 5x5 tent and my plants love it! I also like it does not run hot and is easy to adjust the brightness and also the light height. Great light and great value!

This thing is plenty powerful for a 4×4. Stunning brightness, and control to any percent of dimness manually. =) My little darlings grew like weeds. LOL

It’s good, but the reason it gets four stars and not five is because they kind of needed to add a little bit more to the light for people to use, they had two bigger style C clips that I suppose is for if you want to keep your light at the top of your tent and just hook in each side and keep it at the top it would work, but if you want to adjust your light by moving it up and down, those clips will not work for you. It’ll be all off balance and they don’t include for smaller clips so you could put two in each side to rig something up. I had to rig up something myself on four spots and then run a rope to connect them in order to be able to move my light up and down and have it work like it’s supposed to. Other than that, it works great you can control it within the app from the little box that is included with this light.

This is light is amazing. The adjustable dimmer is great. They don't raise you power bill as much as other lights.
