The HIR1 (9011) and HIR2 (9012) Halogen Infrared Reflective bulbs have micro-thin layers of electro-deposited coating on a specially-designed bulb. The coating reflects the filament's infrared (heat) back onto the filament, which results in a hotter filament that produces more light without increased power consumption, shorter bulb life, or extra heat production. <----- The picture to the left is the original GE prototype.
