Part # PX100
12V Galvanized Steel Intermatic Transformers PX100
These Safety Intermatic Transformers are specifically designed to supply 12 volts to pool/spa lights, submersible fixtures and outdoor garden lights. A grounded shield between the primary and secondary windings assures safe operation and the built-in circuit protection will disconnect power to the intermatic transformers in case of defect or overload.
Should this transformer be wired in before the switch or after the switch? IE: should it always have power to it, or should the switch control whether or not the transformer gets power?
Hi, Chris. The transformer will be placed after the switch. So the switch will control the transformer.
If I installed this transformer to my existing light which is 300 watts could I then use a lower wattage bulb?
Hi, Sean. Yes, you can use a 100 Watt 12v bulb if one is available for your fixture or else you will have to replace the entire fixture.
I have to 120V pool lights (2) that I want to convert to 12V to then install LEDs. Are there any transformer compatibility issues with these transformers and the LED drivers of different manufacturers? Also any reason not to spend the extra few $ to buy the 300W transformer to future proof i.e. when higher wattage LED pool lights are released?
Hi. There is no compatibility issue with these Intermatic transformers and pool light. I would recommend getting the 300W unit because of its load capacity.
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.
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.
Does it come with a built in timer?
Hello Tony, this is just the transformer there is no timer.
How much does this weight?
This tranformer is about six(6) pounds.
I am going to purchase two 12 Volt lights do I need to purchase a transformer with these lights?
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.
Is is this transformer weather proof?
Yes the Intermatic transformer is weather proof.
(5 out of 5 stars) Low-voltage pool-light transformer
Reviewed By: John C. from Calabasas, CA ()
Pros: Low-wattage, small size.
For a "400-W equivalent" LED pool light you really only need 70 W of actual transformer power. This 100-W transformer was installed with my "400-W" LED pool light and it is working like a dream.
(5 out of 5 stars) Great Transformer for pool lighting applications

Pros: Works great, cost efficient
I have used other transformers of which none perform or hold up like the Intermatic for our applications in a wet/pool environment.
