The Toshiba 9011 and 9012 Halogen Infrared Reflecting (HIR) bulbs have micron-thin layers of electro-deposited coating on a special spherical bulb envelope (Chamber). 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.
