Question

Which of the following is the most energy efficient light fixture?

Answer 1

• Incandescent electric bulbs are often used for lighting but they also give heat. It means that a part of electricity consumed is used in producing heat.
• This is not desirable as it results in the wastage of electricity.
• The fluorescent tube-lights and compact fluorescent lamps (CFLs) are better electricity efficient lighting sources.
• Nowadays, the use of light emitting diode (LED) bulbs is increasing. For producing a given intensity of light, LED bulbs consume less electricity as compared to incandescent bulbs or fluorescent tubes or CFLs.

Thus LED bulbs are much electricity efficient and therefore being preferred.
