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.
It's really bright and can be dimmed with a button. I love this lamp and feel it is doing a better job stimulating my cactus to grow than my previous lamp.
It's separatable from the lights, but i can't find a matching brick to use with this. Never worked. Also, could not turn off individual lights as advertised.
