The on button is the one closest to the usb plug. The light is nice and bright and it comes on a telescopic handle that allows you to adjust the height. The plugs are usb, but they come with adapters.

I wish it had a timer but that’s a lot to ask for this price point. I usually keep it on until the powerbank goes dead and then swap it out with a charged one the next day. Timers allow you to put it on for 8; 16; or 18 hours. That annoys me a little ...  Read More

Definitely promotes growth and the price is really good. The telescopic pole is a nice touch. I have several plants in my office that were riding the struggle bus and decided to give these grow lights a try.

These lights emit great light for seedling growth. They emit lots more light than the ones i had before. I have several grow lamps, and these units seem to provide the right spectrum to spurt growth.

The lights are good! They work great and are long lasting. Packed well. I solder it back and it works like new.

Price and performance make these excellent for our 2'x4' space. The possibilities are limitless. My only recommendation is to have these available in a 4ft length and half the width, as well as the square format.

The hanging device is great. They come with cable hangers and cords. Would have been better if the hanger was split into 2 sets of 2 wires.

Neither light powers on when plugged in. No switches or fuses to check. Not the stated 45 watts.

The lights have to be basically on top of the soil / seeds to be beneficial.
