Smart Grow Light for Indoor Plan... vs Plant Grow Light,yadoker LED Gro...

The device blinks and then pairs easily. Brightness is good - there are two modes - sunlight and grow. Varied brightness w/a timer and has an app.

The app allows for customizability that you wouldn't get with a controller. Once set up, it does all the fun stuff on its own day to day.

The light itself is basic with a power button and light dimmer switch. The dimmerswitch has two levels of light, that's not what the description says.
