The light works ok, but the timer does not work. The light just stays on indefinitely, unless manually powered off using the remote.

The timer is great! The timer has 3 settings. After you turn it on everyday you then select how long you want it to stay on. These lights are super bright for 20w.

I normally use a t5 * setup they are so picky. They're light weight enough that i was able to mount them on the underside of a shelf i already owned. The greenhouse is metal frame with lightweight wire shelving.
