40 Watt Transformer by Aurora Deck Lighting provides safe 12V AC power to your low voltage outdoor lighting. Use for installing low-voltage outdoor deck lights.

  • Maximum output 40 Watts.
  • Weather resistant plastic housing
  • For incandescent and LED lights
  • Built-in photo eye and timer


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. 

AC or 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.
