According to SAE (http://www.sae.org/ohmag/prodguide/components/08-2001/page5.htm)
HIR-coated bulbs
Harison Toshiba Lighting, Inc. has developed halogen infrared reflective (HIR)-coated bulbs for forward lighting of trucks and heavy equipment. The HIR-2 low beam is a 55-W bulb that produces 1875 lumens, representing an output increase of 87%. The HIR-1 high beam is a 65-W bulb that produces 2500 lumens, a 47% increase in output. The large gains in luminous intensity are the result of the company's process of applying more than 25 IR coatings to the exterior of each bulb. Production of these bulbs has begun in Japan.
