 Works well

Your questions that we answered:
Ask a questionWhat does this mean "Dimmable on trailing edge (12V side)". How would this work with the TR-L-TS2-72-1 since that would have to dim on the "leading" edge of the lights??? The description seems to be contradicting itself???   - Asked about product TR-L-DC-ELT18-CON-1
 AnswerTR-L-DC-ELT18-CON-1 is 18 watt capacity, plug in power supply. All of the plug in power supplies are designed to plug into a standard wall outlet and dimmable on the trailing edge (low voltage side). Basically you're power supply can only use a dimmer that operates on the low voltage side of the power supply. The Plug In power supplies can not be controller by a standard wall dimmer. Wall dimmers are hardwired and would try to dim the high voltage of the power supply, this does not work with Plug in models. We have Hardwired power supplies that work with wall dimmers.
