Comments

Caution!

Make sure you pick an LED driver/transformer that comes with the appropriate power rating.
Choose a driver/transformer that supplies approx. 30 pecent more watttage, as the current consumption (i.e. amperage) of the LEDs is key, and not the power rating of the LED provided by the LED manufacturer.
Keep in mind that the switch-on surge tend to be much higher.
