I am going to purchase two 12 Volt lights do I need to purchase a transformer with these lights?

A  Answered on 12/16/2006 by InyoPools Product Specialist Patrick P.

The power coming from your house is 120V so you will need to purchase a transformer to drop the voltage from 120V coming from your house down to 12V going to the pool light. We sell two transformers the PX100 which can handle up to 100 watts and the PX300 which can handle up to 300 Watts. You may also put multiple lights on one transformer, for example if you had two 50 watt lights then you would only need to purchase one PX100 transformer and wire both lights into this single transformer.

Hello Tony, this is just the transformer there is no timer.

Is this transformer designed to be switched on and off? Or should the light switch be on the 12vdc side? Just wondering if anyone has had problems with the inrush current of the transformer? The reason I'm concerned is because the LED light I was looking at requires power to be switched on and off to change the color/light show.

A  Answered on 10/12/2016 by InyoPools Product Specialist Scott W.

Turning the light on and off as well as changing the colors is going to be done by switching the light switch on and off, the transformer does not have the switch for that.
