Best Light Ever Doesn't Run Up Electricity!
This is my first grow light and I've had it for a little over 2 months and it works wonderfully! So many of my plants have grown from this little light. Has not ran up my electricity bill at all barely made a difference. I like that it comes with a remote so I can set the brightness and the timer. I haven't touched it since I set the timer and it comes on everyday at the same time and turns off at the same time as well. Of course it was easy to install unless you don't know how to screw in a lightbulb lol.

No heat output, my plants are happy!
I purchased this for my house plants during the winter. I love that you can turn it on at a certain time, set the time for 4, 6, 8 or 12 hours and it will come back on every day at the time you first set the timer. My plants are happy, a lot of new growth. This light does not put out any heat, I was concerned about that. It's a great bulb!

Does what it should :)
My pothos is happy, so I'm happy. This bulb works with any lamp. The remote has a tab you pull to activate the battery. I'm not sure if the remote battery can be replaced. The color is a cool white. There are options for how much light you want on your plant (1/4, 1/2, 3/4, or full power) and different time options. I really love the timer feature. I haven't noticed any heat coming off this bulb. The bulb is nice and bright. I think the cost was reasonable for what I received.

WONDERFUL!
I love these bulbs!! They are affordable and efficient. I love how you can put them in any type of light. The remote feature is very nice, making it easy to turn off and on, dimmable, and provides a timed option. We have one in a lamp stand that sits over our Monstera deliciosa, and it loves it!

Works well but if you have two or more it might be a problem
The light bulb itself is great and good quality. Plants thrive under it. The problem is if you have more than one in your house the remote is going to control all of them. So you can't set them to different settings because they share the same remote which I'm thinking is unintentional. I wanted one on a different setting in a different room but I can't get it programmed because it reprograms the one in the first room

Saved my plants!
These lights have saved my indoor plants! I have over 40 plants and use these bulbs in livingroom can lights. All my lights are happy and I get a little UV light too. Great indoor plant option!

So far it Is working well
I must say in advance that these bulbs should never be used in a closed shade. These lamps get very hot. If you want your shade to look cute, then get something like wicker, rattan, or rod with open spaces. I had a 36w bulb with a rattan and white cloth shade. I could not touch the bulb and felt heat coming off of it. Once I removed the white cloth shade, it still looked cute with the rattan shade and there was no heat. I read some of the reviews with several people having issues with the remote. I have had it a couple of days and the plants are loving it. I ordered a floor lamp I am waiting for, but I was able to screw it into a ceiling fan light fixture with an extension for now and the plants are drinking up this light. I love the remote feature that is working well so far. I am considering purchasing another for a hanging grow lamp. What is nice is you can use these bulbs in any regular lamp so long as the socket on both are compatible.

Love the timer
There is nothing bad I can say about this bulb. I love the fact that the timer works and comes on everyday at the same time for the same amount of time. I love that I can adjust the brightness and my plants love it too!
