Question: what are two differences between leds and incandescent bulbs?
Answer: LEDs use much less energy than incandescent bulbs because diode light is much more efficient, power-wise, than filament light. LED bulbs use more than 75% less energy than incandescent lighting. ... Bright LED flood lamps use only 11 to 12 watts while creating a light output comparable to a 50-watt incandescent bulb.
