{'incandescent bulb': [0, 0, 0, 1], 'light emitting diode': [0, 0, 0, 3], 'power consumption': [0, 0, 2, 1], 'fluorescent tube': [0, 0, 1, 0], 'cfl tube': [0, 0, 0, 1], 'correct order': [0, 0, 2, 0], 'equal intensity': [0, 0, 0, 1], 'light': [16, 4, 34, 62]}

Option 1: CFL tube < Fluorescent Tube < Incandescent Bulb < Light Emitting Diode

Option 2: Light Emitting Diode < CFL Tube < Fluorescent Tube < Incandescent Bulb

Option 3: CFL Tube < Fluorescent Tube < Light Emitting Diode < Incandescent Bulb

Option 4: Incandescent Bulb < Light Emitting Diode < Fluorescent Tube < CFL Tube

The correct answer is option 2: Light Emitting Diode < CFL Tube < Fluorescent Tube < Incandescent Bulb.

In this order, the power consumption increases from the Light Emitting Diode to the Incandescent Bulb.

A Light Emitting Diode (LED) consumes the least amount of power compared to the other options.

A CFL (Compact Fluorescent Lamp) tube consumes slightly more power than an LED.

A Fluorescent Tube consumes more power than a CFL tube and an LED.

An Incandescent Bulb consumes the highest amount of power among the options.

Therefore, the correct order of power consumption for light of equal intensity is:

Light Emitting Diode (LED) < CFL Tube < Fluorescent Tube <
