Question

Based on the above table, which of the following statements would be true?
a) Halogen and Incandescent lights consume 10% more power than CFL lights.
b) For an output of 1000 lumens LED lights consume upto 5 times more than the Incandescent lights.
c) There is no difference in power consumption for lights of low lumens in the three categories.
d) For an output of 1400 lumens CFL lights can consume upto 90% more power than LEDs​

Answer 1

Answer:

b

Explanation:

because for an output of 1000lumen led lights consume upto 5times more than incandescent bulbs

Answer 2

Answer:

Correct option is d) For an output of 1400 lumens CFL lights can consume up to 90% more power than LEDs​

Explanation:

Incandascent lights: A classic light bulb producing light by heating a wire filament to a high temeperature to generate light.

Compact fluorescence light (CFL): A twisted or turned, compact fluorescent tube, that produces light by driving electric current through a tube containing argon and a small amount of mercury vapor, generating UV light that excites a fluorescent material (phosphor). It is much energy efficient as conventional incandascent lights.

Light emitting diode light (LEDs): It produces light when a current is passed through a semiconductor device. This is more efficient as CFL.

As per the given power consumption and light output data,

For 1400 lumens, a CFL consumes 30-55 watts power while an LED consumes 25-28 watts power  which is 90%.
