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.
Timer holds your setting does not need to be reset daily. I leave them plugged in and they come on automatically daily. Easy to use and portable.
Only complaint is that the extenders are not long enough. Ability to change colors as well as dim/brighten lights is great too!
Light clamp is strong, holds securely. I have a 2 tier plant stand and the necks of the lights easily reach both tiers.
Lamps no longer work. Control panel no longer lights up as well, indicating an electrical malfunction outside of the lamps. The cord gets extremely hot. The controller still lights up while plugged in.
It's now past the return window, so i'm up the proverbial creek without a paddle. Do not waste your money, time, or sanity with this light. Buyer beware.
