The Vivosun Growhub is a grow room controller but is also an excellent stand alone grow light controller. It can be directly connected to grow lights that have an RJ11 port (network connector) for 0-10V dimming signal control. The RJ11 network cable is included in the standard Growhub package.

The Vivosun Growhub can be used to directly control the grow light dimming which can turn the lights on and off to your lighting schedule including a sun rise and sun set function.
You can also connect the Growhub to the Vivosun App so you can control the grow light remotely.

In addition to controlling the grow light you get temperature and humidity readings and historical data so you can monitor the grow room environment.

The Vivosun Growhub is currently $49.99 (less 15% if you use the code 'MIGRO' at the checkout) which is the best value grow lighting controller on the market at the moment.
