Cool lights. I like how they can all run off of one setting when linked. They do not daisy chain the power supply so make sure you have enough open sockets for them. I paired them with the vivosun digital timers, works great.

The light is mot strong enough.

My plants love this light. I have a shelf with some plants that were just not getting enough light, and within a week of putting this up for 12 hrs a day, the plants have a bunch of new growth.

Please understand that this is not on the same level as the strips that you install on the bookshelf, this thing is BRIGHT. I have it shining on my plants on one wall, and it provides light to the rest of the room equivalent to a medium sized window. So don't get this for the cute aesthetic vibe - get it for the health of your plants, if they need it.

I see some people took of stars because it's too short, but it is advertised as being a clip on light, and basically looks exactly like the picture. No, it doesn't haven an extender arm, but it wasn't advertised to.

I replaced a bunch of T12 fluorescent tubes in my garage with these bulbs. The G13 bases fit perfectly into my tombstones. For one type of my fixtures, these bulbs were a hair too long, requiring me to push the tombstone on one end to allow the pins into the socket. No problem, though, and it makes a nice, tight fit.

These bulbs are as bright as I had hoped that they would be. Because of the clear glass envelope, the LEDs are very harsh to look at. I decided to turn the bulbs "upside down," with the LEDs pointed up into the fixture, and there is plenty of light reflected off of the fixture and ceiling. If you have a lens over your fixture, the harsh LEDs will not be a problem.

I love these things!

These are awesome grow lights. Compact but pack a powerful punch. The plants seem to crave this light over the sunlight through the window

Being out of season I thought it would be a good test to see what lettuce we could grow with the kids. They planted the seeds which germinated. We affixed this light over the top of a metal shelving unit and it left it to do it's thing. The rapid growth of the lettuce is a testament to how efficiently this works. I would be very happy to recommend it and will be using it in the spring to germinate the seeds for our garden.
