Answer - C - The standard life expectancy of a compact fluorescent lamp is 10,000 hours.

Key Takeaway: A Compact Fluorescent Lamp, or CFL, uses less power and has a longer rated life when compared to general incandescent lamps giving the same amount of visible light. CFLs are produced for both AC and DC input. The average rated life of a CFL is between 8 and 15 times to that of the incandescent. CFLs typically have a rated lifespan of between 6,000 and 15,000 hours, whereas incandescent lamps have a lifespan of 750 or 1,000 hours.
