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.
Power supply shows that it's not even close to 300w worth of lighting. Specifications for the listing are a downright lie.
