Why upgrade from incandescent to compact fluorescent lamps (CFL)?
- An incandescent lamp is a better heater than a light, with nearly 90% of the input energy being converted and lost in waste heat.
- ENERGY STAR qualified CFLs use 75% less energy than a standard incandescent bulb and last up to 10 times longer.
- A CFL can save more than $40 in electricity costs over its lifetime
- Although CFLs cost 3–10 times more than comparable incandescent bulbs, they last 6–15 times as long (6,000–15,000 hours).
