The box comes with a canopy unit with a twist air vent. These seal well and perform as expected for starting seedlings.

Nice little kit. Decent quality for the money. Happy with purchase. Will buy more. I feel these are a good value and recommend them.

They're sturdy enough to be serviceable under moderate use. The are lightweight plastic, but with careful use you could use them for many seasons. Sturdy enough to reuse multiple times.

The clamp on the light is an added bonus. I have it hooked to a small 3 shelf set up hanging on my wall. I really like the clip-on feature; it offers more flexibility for adjusting the gooseneck dual head lights.

It definitely perks up my plants. I see my plants responding to them and growing very well.

Choose the light intensity and duration for your type of plants/seedlings/cuttings with 3 light spectra, several levels of brightness, and 3 timer settings. The timer function is my favorite. My only frustration is that the timers vary.

Picture appears to be black lamps, but they are infact silver in color. Cord is barely long enough to reach from above my aquarium to the wall outlet. The timer on this is pretty inaccurate.

This light is in a bedroom, so with it coming on earlier and earlier is a problem. It flickers and gets dim. It constantly turns off and changes brightness.
