To calculate the size required for your installation, simply multiply the quantity of fixtures by the wattage of each.
12 pc IL6.250 Xenon (11.5 watts each) = 138 watts minimum required
12 pc IL6.250.500 LED (2.4 watts each) = 30 watts minimum required
Low voltage (12 volt) transformers do not output a standard 12 volts. They output a fraction (typically 10 percent) of your power input. To maximize the life of either your bulb or LED, be sure to confirm the output power with a digital volt meter.
