Barrina lights have a simple power supply and individual switches on each unit, perfect for running on a timer. You can daisy chain them and use them with a smart plug. They interconnect well with the other sizes.

The brightness is alright for what i need, but i do wish the lights were a different color. They are quite bright and seem to be working for the seedlings just fine. They fit great and wonderful lighting for my plants.

The lights are not obnoxious or anything like it. So far my plants look and feel so much happier. Great product and my plants thrive.

Irritated is an understatement. Now i'm stuck with having to buy another pack and redoing all the work. If this company decides to honor the 2 year warranty on the product description i will most certainly update this review.
