Small enough for shelf, came with everything needed to neatly place lights. Pretty bright.

This was very easy to set up, the light is very bright and is great for the plants that I have on my shelf because it's hitting all the levels of the shelf.
There is a timer feature on it that you can send it to 4, 8, or 12 hour increments. And you can set the lighting so only the bottom two or just the bottom light is on, if you don't need all three segments on.
I'm not able to change whether it is white light versus warm light so if you're looking for something that has a more warm light tone, that's just something to consider.

Overall, this is perfect photo I was looking for.

I needed a light that would keep my Norfolk Island pine tree alive during the PNW winter season. My tree is about four feet away from a frosted west facing window, which doesn’t get enough like during the off season. I love this light, it’s a million times better than those arm led lights that are all over ecogrowhawaii.com or the stands that only give light on the top of the plant. This one actually works! My tree is very happy under it and it’s so bright. The brightest light I have so far. Only downside is there is no timer. The light was easy to get set up out of the box. I am so pleased with this, it’s just like the professional grow light tubes that hang from the ceiling, except it’s able to be aimed at the the whole height of the plant, perfect for trees, and I bought a separate timer for the light to go off for 12 hrs a day. Very reasonable price for such a useful grow light. The back of the light does get warm to the touch, but not hot enough to hurt your hand or burn anything. The front of the light is not hot or warm to the touch whatsoever.

The clamping hardware is very flimsy and does not do a great job of holding the lamps.

This light is a great match for moderately sized indoor plants. Well built yet compact, easy to use, and functions as advertised. For the price I feel it is absolutely fair.

This was the perfect size for my little grow tent. I had to get creative with the mounting but that kind of goes with the territory. I've been running it on a timer for the last few months and it has worked well. Some cosmetic issues and I'm not sure why there are cooling louvers that are not even open enough for air flow, but nothing important, the light has worked great. My seedlings have done very well.
One note of warning, I am pretty sure when I received this, the power cord was packed into the bulb/reflector side to save space and fit it in the box, with some foam padding. I initially packed it back up because I wasn't ready to use it yet. When I unpacked it, I found the reflector was dented in the center, where the power cord was. I don't believe it arrived this way, I'm pretty sure I was responsible for this when I re-packed it. It hasn't affected the performance but really bugs me when I see it. My advice is to check for this when you receive the light, and don't try to repack it!
