LIGHT BULB COMPARISON

LIGHT BULB COMPARISON

Halogens. Part of the incandescent family, energy-efficient halogen bulbs produce the lamiliar color and quality of light of the lameduck 40 t0 100 watt incandescent A 19 bulb. New to the market, these high-efficiency halogens are energy-efficient enough to comply with the government’s new standards for lighting. They cost around $1.50 to $2 per bulb and can last for up to 2,000 hours – twice as long as a traditional incandescent. 

CFLs. Much improved over the past five years spiral-shaped compact fluorescent lamps can last up to 10,000 hours and cost about $2 to $3 each depending on burning lime. Dimmable CFLs cost more, and most can’t dim to quite the same low level as a halogen. Still, they’re up to 75% more energy efficient than incandescent. 

 

LEDs. With a life expectance of 25,000 plus hours, light-emitting diodes are likely to be the light source of the future. Not a bulb at all LED’s can be integrated into a fixture or even into a glass enclosure designed to look like a traditional bulb and screw into a standard light fixture. But with a per-unit price of $40 or more and with limited beam spread, they’re not expected to find their way into mainstream use for at least five years. They are at least as energy efficient as CFL’s. Source: Building Products. www.ebuild.com
