    What kind of lights are you planning on using, and how many of them?

    Do you know the wattage rating of the lights?, or voltage @ current if LEDs?

    Ok, the bulbs have a rating of 2 Watts each, or 2 Watts for the three of them?

    Does the LED have a current limiter circuit built in, or is there an external resistor on it?
