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.

The gooseneck is sturdy and holds its position. They are easy to setup and use and the clips are fairly sturdy. The clamp is strong and can accommodate about 1. Feet. These are perfect for shelves.

These are really, really bright! I hope my herbs perk up. My moth orchid has so much new growth.

Uses a usb charger, so i wonder whether it is the best light. My husband's office is in our basement and is really lacking light, but he really enjoys having plants down there to cozy up his desk area- these are absolutely perfect for this.

Lights are very flimsy and am very unsatisfied and will be returning these lights. Not worth the use imo. One of them is defect. It's frustrating that i need to unplug and replug it.
