Any low voltage LED bulb that runs on mains circuits requires a compatible driver. This LED driver from Integral LED reduces a standard 240v mains output to the 12v required to run low voltage bulbs and delivers enough power to accommodate a 20W LED lamp.Fully compatible with 12v constant voltage LED lighting systems, this driver provides up to 1.67A of output current and includes protection from overloading, overheating and short circuits.The driver\'s slim profile fits comfortably in a range of confined spaces, making it perfect for use with MR16 or MR11 spotlights that are often found in ceilings or other recessed fixtures.
