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.

Fast shipping, good packing. No frills plug and play, have had 3 running wide open for 8 weeks with no problems.

It fits gorgeously in my 3x3 tent, 4 plant dwc * set up. The dim setting works well and the separate ballast has a cord long enough to hang ballast outside the tent to help with reducing heat. Right next to him is my baby jalapeño, cortez.

This product is a cheap chinese knock-off, which will break after one use. Stay with reputable companies, and away from mars hydro. The board cable connection is very fragile.

The led diodes get hot and have burned my plants at 30 away. The shroud is really too hot to touch. However it is dimmable and very seldom goes over 60%. Less bright than my mars hydro sp150 and sp200 units.

This light supposedly has a three year warranty and mine lasted a year. Can seem to get these warrantied (was supposed to be 5 years) they claim a 5 year warranty on the drivers.
