Because they produce only a small amount of heat, these highflux bulbs make ideal replacements for most "third degree burn" halogen reading, map and cockpit lights with bi-pin and bayonetstyle bases. Light is soothing and warm with cutting edge internal circuitry and high-quality U.S. made components for long service life and shock resistance. Power consumption is just 1W (less than 0.08A!) except for three-watt Model 9980111. For forward pointing reading fixtures only.
