Final answer:
LED backlights are more energy-efficient and durable than CCFL backlights, consume less power, have a longer lifespan, withstand rough usage, and do not require hazardous waste disposal, despite their higher initial cost.
Step-by-step explanation:
Comparing light-emitting diode (LED) backlights to cold cathode fluorescent lamp (CCFL) backlights reveals several key advantages of LEDs in energy efficiency and durability. LEDs require less power for the same light output, providing significant energy savings.
For instance, a 60-W incandescent bulb can be substituted with a 6- to 8-W LED bulb, both producing about 800 lumens. LEDs also boast a longer lifespan, with up to 50,000 hours of use, compared to the 8000 hours of CFLs, and are more durable, able to withstand rough treatment without breaking.
Additionally, LEDs do not contain mercury, avoiding the hazardous waste concerns associated with CFL disposal. However, initial costs for LED bulbs can be higher, although they may offset the investment over time due to reduced energy consumption and replacement frequency.
