Product FAQs


Q:How much does this weight?

A:This transformer is twelve(12) pounds(lbs).


Q:Can you hook up more than one light to this transformer?

A:The PX300 is a 300 watt transformer. You can connect multiple lights to the transformer as long as the total combined wattage does not exceed 300 watts.


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

A: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.


Q:Is is this transformer weather proof?

A:Yes the Intermatic transformer is weather proof.

The transformer arrived in two days. Shipping status was great. Only issue was the wiring diagram was in french. Quick lanquage lesson solved the situation.

Pros: Does what it's supposed to.

Cons: Kind of noisy, mount it away from where you will be.

Had it for nine months with an Intellibrite systems, works OK. It does make noises when the lights are programming (the controller programs the lights by powering off and on rapidly a set number of times for each color or program), and hums a bit otherwise. I have it mounted on a back wall behind a screening fence, still can hear it.
