When set to run for 12 hours, the light shuts off and does not come on the next day. This defeats the purpose of the timer feature.

The cords are lavishly long, which is nice. With 4 lights it makes it easy to modify for your setup. The timer is also a big plus.

I only wish that i could dim them because they are super bright!

Each fixture emits ample light. The light stays cool while emitting the perfect amount of light for seedlings and clones. Because our setup our seedlings are getting both natural light through the window. And strong sunlight.
