Too bad they could not figure out that technology for all halogen bulbs.....Would be great. Only a small number of rigs use these bulbs.
As far as I know, nobody makes true HIR bulbs anymore. There are still 9011/9012 bulbs sold, but they are a standard 65w capsule bulb on a 9011/9012 base. True HIR bulbs are spherical in shape, and have an INTERNAL coating that is slightly visible with the naked eye. Minimal improvement from a 9011/9012 upgrade anymore, as it is just a standard tungsten halogen bulb.
