Product Specs
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.

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

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.

If a use a 300 watt transformer but only have 75 watts of LED lights does the transformer consume the 300 watts or the 75 watts being used by the LED lights?
Reply
It would only consume the wattage needed. No more.

I located the wires running from the electrical box to the junction box for the pool light. I found a point where I could split the wires to connect it to the Intermatic 300 watt transformer. I turned off the breaker for the power supply to the pool light. I dug until I found the PVC conduit for the light and cut it in half (after verifying the power was off).
I then routed the wires coming from the home to the location where I placed the transformer and then routed the wires going to the junction box for the pool light as well. The wiring instructions on the back of the transformer's lid was easy to read. I then had to replace my pool light to a 12 volt light and run the wires to the junction box. I made the connections and proceeded to turn on the power.
Everything worked! Very easy to install.

The transformer install was the one step that I hired an electrician to perform since it required conduit and we added an additional breaker to the Jbox. The installation was about the same cost as 1 new Pureline color-changing LED bulb.

(5 out of 5 stars) Good unit. Not too noisy. Steady voltage.

Heavy, but easy to install. Others have complained of a loud buzzing. The unit I installed hums, but it's not that loud. Granted, I installed this in our pool house (where all of our controls are), you can't hear it in the pool. Before I connected the pool light, I measured the voltage output with a multimeter. The voltage was steady at 14v.
