If you have indoor plants, these are a must have. The built-in timer function is really nice so i can set it before leaving for my day. The 10 brightness levels lets me pick the right one depending on how close they are to the plant.

The clamp is quite strong and there are multiple settings that are easy to use, so those are the good parts. The other pros are that it is affordable.

I give the light itself an a-rating - worked wonders to help revive a sad plant - but the timers seem to have some inconsistency. The 3 hour timer is the best.

This light is pulling less than 10 watts. I am able to run this lamp on a 2 amp usb charger and it never even gets a little bit warm. One week past return expiration date.
