Easy to install with supplied clips and screws. Comes with all the attachments you need. There are jumper cords to connect fixtures so that only 4 power source cords would be needed.
Small and lightweight, a 10# command hook holds it up. Been using it for veg with my photoperiods and one autoflower. The cooling fans keeps the unit cool.
I also like the new design with the holes in between the leds lights, it helps the light run cooler than other i have purchased previously.
