A lot of work has gone into making the blue power LED more efficient so white-light diodes can be more efficient. With white-light LEDs producing more than 200 lm/w (Cree) at power levels of 1W the basic efficiency of the blue LED is over 50%... My question is: does anyone know of an InfraRed LED manufacture that markets a ~1w IR LED that has greater than 10% efficiency?
