MARS HYDRO VG80, 4ft Led Grow Lights for Indoor Plants, 5000K Full Spectrum, 2x4 Coverage, IP65 Waterproof Linkable Under Canopy Plant Light Strip for Seedling Veg Flower (2x40W, 450W Equivalent)

My plants love these lights.

Good universal mount lights. I use them as under canopy lights for a 2' x 4' grow tent. They put off a good amount of light and don't get hot at all. Excellent addition to achieve more even distribution of the DLI for your plants.

Fast shipping, very good quality grow light, would like to purchase again.

The good. The lights work well, produce very little heat, and I had no problem daisy chaining them together.The bad. The cables are a lot messier looking than they look in the photos. For starters, they are much longer than shown. Great if you want the lights spread apart but unwieldy when the lights are close together. Also, whether you chain multiple lights together or even just run one, you’ll always have a trailing cable just hanging off the end.Also, I don't understand why they package a timer with it. Just extra trash that got thrown out, I have timers already.

Great light

These guys are just not that bright as opposed to generic light which would produce about 800 to 1200 diodes.It looks like there’s about 170 individual LEDs per bar. That’s a rough count. Thats 340 lights as opposed to 1000 lights.If you’re looking for serious red lighting, do you wanna go with the Mars Hydro capital SP 3000 R. Despite being nearly 3 times the price, He has approximately 804 different LEDs Which is more than three Times the light output.

First time starting plants from seeds(in soil blocks) so this is a learning experience for sure. I purchased a Mars SP150 roughly a year ago that I had not been able to use until now. I profess I'm probably using it incorrectly. My tomatoes became leggy as I had the light too far away & I potted up due to the leggy seedlings. The SP150 puts off quite a bit of heat. I turned to the VG80 and things are looking great. Well packaged, well made, and you can really see the thought put into this product. Easy to assemble, and I love how the lights utilize a wire and screw type clamp to adjust height. So much nicer than chains. Unscrew the clamp, move the wire, tighten down the screw and you are done. Plants immediately perked up, and are growing on well. Heat is not an issue with these lights.Adding - 50,000 light life. Others are 30,000 or less.

Very well packed and came with explicit directions that were very easy to follow. Extremely easy to set up. Been using them for starting plants and it works excellent. lightweight and easy to work with. They also look really good. For the money, these lights will treat you right.
