Sanlight Bluetooth Dimmer EVO Series

With the keyed dimmer you have to reach the fixture to change anything. This one runs over Bluetooth instead. Plug it into the dimmer port on a Sanlight EVO panel and your phone does the rest. A light hung high in the tent, or up on a top shelf, becomes as quick to adjust as one at arm's length.

The power still moves in steps, exactly like the keyed unit. Pick the level that suits whatever is growing under it, a seed tray one week, a heavy fruiting canopy the next.
