The cooling fan's air passes through the area needing to be cooled. Has just enough power for 1-2 small to medium sized plants from seed to harvest. Works really well in my 3'x6' greenhouse.
Thumbs up. The timer is a must have. Fully adjustable brightness is great.
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.
