No instructions but much straightforward. It works fine. I have a big monstera albo, a small florida ghost, a yellow oxalis, and a variegated philo cutting underneath it. It is also energy efficient.

This thing is awesome! Very pleased with this purchase. I love that i re-potted my plants in the dead of winter and they are thriving so well like they are outside and it's not summertime.

The timer works really well in 3 different settings. Sometimes the timer needs to be reset when there is a power outage. I can see the the plants have perked up in the day that i have had it - so it seems to be giving them what they need.

The clip is very strong and sturdy. The base is a clip so i can clip it to my shelves and place the light rods where i need them that day.
