Light sensing transformer for outdoor lasers using 120volt ac converted to 12volt dc. This unit will have from 80 to 120 watt capacity for operating one or more units depending on their wattage capacity. The Spright uses up to 8 watts each and the LS20G up to 35 watts each.

This unit senses darkness and turns on the power to your lighting system at dusk.
You can manually dial the control on or off or leave it set to turn on at dusk and stay on for 2, 4, 6 or 8 hours or until daylight.  

Wire to connect these lights to the transformer and to other lights is not included but readily available in rolls at most garden supply stores.
