LED vs. regular lightbulbs: Do they really make a difference?
Updated: May 11
Although the incandescents had a good run, we suspect they’ll soon be obsolete. The simple fact is that YES: LEDs use much less energy. Diode light is much more efficient, power-wise, than filament light.
LED bulbs use over 75% less energy than incandescent lighting. At low power levels the difference is larger. Bright LED flood lamps use only 11 to 12 watts while creating a light output comparable to a 50-watt incandescent.
