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.

It has a timer, which i am thrilled with. The plug is a usb adapter (unlike some led plugs that cover up other outlets.

Though small, this light produces a good amount of light. Its output isn't as strong as my others but its exactly what i need for where its at and the plants its feeding. Nothing to complain about.

I'm confident that with this light, my plants will get adequate light year round and they will thrive. My plants come in from the deck in the winter months.

The light is bright and easily dimmable. Perfect for plants that need bright light and those who prefer more filtered or shaded settings. The controller is easy to use, as it is color coded.
