How do LED lightbulbs work?
An LED bulb produces light by passing the electric current through a semiconducting material—the diode—which then emits photons (light) through the principle of electroluminescence. Don’t let that big word scare you! … In contrast, an incandescent light bulb works by passing electricity through a small wire, or filament.
Do LED lights make your electric bill high?
LEDs Use Less Energy Than Traditional Lighting Sources
LEDs use between 25- and 80-percent less energy than incandescent lights. According to the DOE, the annual energy cost of a 60 W incandescent light is $4.80, but the comparable cost of a 12 W LED, providing the same light as a 60 W incandescent light, is $1.00.

Are Edison bulbs always yellow?
A lower number means the light will appear more yellow, while the higher the number means the light will appear whiter or bluer. The color of the incandescent bulbs we were used to is around 2700K. Any number higher than this will be a whiter color and lower will be more yellow.
Do LED lights burn out?
Unless an actual component in the LED fails, they will provide light “forever.” While LEDs do not burn out like fluorescent lamps and other bulbs they will, however, degrade and dim over time. The diode itself will begin to emit less and less light as the years pass. Still, LED lamps can last over 25,000 hours.
