Lights are lightweight enough to be mounted on the underside of a shelf. Work well for seed sprouting (herbs), baby plants that are rooting, and even provide enough light to produce a fenestrated monstera leaf.

The timer is great! The timer has 3 settings. The plug gets a little warm to the touch after the lights have been on for a while. The timers make it so easy and provide a simulated daylight environment for the plants depending upon their needs.

The power adapter simply does not work anymore. These only lasted 7 mos on 12 hr timer! Would not recommend for the lack of longevity.

Several brightness/dim levels. Timer works well.
