The latest led tech this dimmable 8w lumilife downlight comes with chips on board cob technology which bonds leds together to the circuit board to increase light range and minimise failures thanks to fewer welding points using less power for more light halogens lose up to 90 of energy to heat this is not the case for leds which instead use up to 90 of energy to produce light this led consumes just 8 watts and produces up to 650 lumens of light leading the way in energy efficient light
