They perfectly clamp to every surface i've tried them on. They are very sturdy and clip on yo almost anything. Flexible and can be clipped anywhere. Clamp very strong and keeps light firm.

The timer is an awesome feature, it has 3 settings 3,6 and 9 hours. The only drawback is that the feature * are confusing. Output of heat from the lights is monitored to prevent and burning to your plants.

They also appear to be providing ample additional light to some smaller potted plants high up on a bakers rack as well. This light give great light to my plants and they are growing and blooming. Month of use at 12 hrs per day.

The timer works great and the plants are germinating like crazy. Hope it works to perk up some of my plants! Use for many different kinds of plants. There was nothing deceptive at all in the description.

Even on the brightest adjustment, the light is not enough. It's mid-winter, with no direct sunlight in my windows, so i was hoping to imitate the sun. However this product generates loud radio frequency interference (rfi) noise spikes every 40 khz.

These are great lights for small-medium indoor plants. My pothos loves the grow light. They are healthy and growing nicely.

The timer is awesome- works great so i am satisfied. It works as expected / hoped and i'm pleased.

I also like that it has usb and a regular plug. Only disadvantage is that it cannot be used with a smart plug. They have easy to set timers and seem to be water resistant.

This one is there too as a “helper” but can’t compete. On/off switch glows brightly even when turned off. Only lasted couple days.
