Trex Lighting Transformer

Lighting transformers include a 12v DC transformer that will plug into a standard wall outlet (or the timer), plus a timer and pigtail wire. 

Timer can be set to turn on at dusk for a certain amount of time, or manually be turned on/off.

Pigtails convert the large transformer plugs down to the mini-plugs that run to each wire. 

If a remote/dimmer is desired, it can be connected between the transformer and the pigtail.
