DC Input Constant Current LED Drivers DC Input or Low Voltage LED drivers take DC voltage from a battery or switching power supply and output a constant current so as to keep the LED safe. This way, when the LED's electrical characteristics change due to heat, the LED will stay at a safe driving current, while the voltage can vary depending on the LEDs needs. 120v ac to 12v dc adapter | eBay Find great deals on eBay for 120v ac to 12v dc adapter.
