    How to determine transformer size?

    • Multiply number of lights by watts per fixture.
    • Add 10% for wiring and connections. 
    • Optional: Leave room for more lights in the future.
    • Round up to the next closes transformer size.
    • To avoid early bulb burnout, use at least 50% of the total transformer size. 
    Sample: 24 LED lights x 1 watt per light, plus 10%
    24 x 1 = 24 + 2.4 = 26.4, Round up = 27 watts total
    Use a 36 watt DC transformer. 


    • Always check the lighting specifications for recommended transformer type. 
    • AC transformers are most often used with incandescent fixtures and some have built-in photo eye and/or timers. 
    • DC transformers are used with most LED fixtures. Since LED lights typically require less power per fixture (only 1 to 3 watts), DC transformers are usually smaller in size and are designed in lower wattages. 
    • Some higher end LED fixtures are rated for both AC and DC power.
