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.

Low profile and great price; bright and easy install. Both of these lights are actually a fairly decent size. My only recommendation is to have these available in a 4ft length and half the width.

The hanging device is great. Would have been better if the hanger was split into 2 sets of 2 wires on each short side.

Packed well. I solder it back and it works like new.

Neither light powers on when plugged in. No switches or fuses to check. Not the stated 45 watts.

The lights have to be basically on top of the soil / seeds to be beneficial.
