Excellent light.. Easy to setup. Just as described

So one thing I want to make clear - the item looks a LOT larger in the initial pictures than when you get these. I was expecting shelf sized panels (i.e like 14 x 9 based on the pictures) but the actual pictures for the dimensions ARE correct. These lights also have a simple on and off mode, with three timer presets. When you push the timer preset, the led color will change to match the preset - which is slick. These lights do not dim. However, these are very BRIGHT and make up for their small size with high output! The units also do not seem to heat up after being used for 12 hours straight. You also get many LED lights to cover the spectrum. These are thin and VERY easy to mount.

Pros
1) Do not get hot!
2) VERY bright
3) My use case requires 2 per shelf, so get the 6-pack if you have three shelves.
4) Three timer modes of 4/8/12 and I so far have tested the 12 hour cycle.
5) VERY easy to mount and have great clearance.
6) INSANE amount of extension ports - you could easily expand this - I hope the manufacturer allows us to purchase additional lights with the connection cable in the future
7) option for a battery backup (although that is going a LITTLE overboard!)
8) Lights are comparable to what you see in hydroponics systems.

Cons
1) I think the biggest con for me is the timer length as seedlings do require closer to 16 hours of light. However, for established plants, 12 hour is ideal, and more established seedlings will thrive.
2) Be careful with these and water, as there is no real protection around them.

Final notes, I have two of these per shelf for my indoor greenhouse. On the top shelf are my hydroponics units. My use case is starting the seeds in those units, and moving them to the lower shelfs for continue growth until it is fine to plant outside.

This kit is the BOMB. I'm still working on balancing the humidity but the the kit is complete and verything fits as it should. and my plants love it.

This Outsunny Raised Garden Bed with Polycarbonate Greenhouse is lightweight and could blow away until you fill it up with mulch and plants to help anchor it for high winds. All the parts are well- made and was easy to put together with the included instructions- with a little predrilling here and there and a couple of extra hinges to help secure the top section. Next winter I will run a water line to it from one of my timers and grow some Broccoli inside of it over the cold months. This is a good- functional kit that will produce for the effort- next winter. Innovative design at a good price! Great find!
