Incandescent vs Halogen vs CFL vs LED💡

#lightbulb #energy #efficiency #cost #led #cfl #science #viral #trending These are the 4 main types of light bulbs! Stay until the end to find out which one's the best. Number 1: Incandescent bulb. The traditional light bulb with a tungsten filament that glows when the current passes through it, illuminating the bulb. Used for a cozier effect in living spaces. Needs to be replaced most often. Number 2. Halogen bulb. More efficient than the incandescent bulb, providing 25 to 30% more light using the same amount of electricity while also lasting longer. However, it emits a whiter light, so it is better suited for work places. Number 3. Compact Fluorescent Light Bulb. CFL bulb is even more efficient than the incandescent bulb and is available in spiral or traditional shapes. It also tends to emit a cold light. It contains mercury, so take care when handling and disposing it. Number 4. Light-Emitting Diodes. L.E.D bulb costs even less to run and produces less heat while also lasting longer than an older style bulb. LED bulbs come in a range of colors and styles and boasting a wide range of smart features. As you can see on this graph, as the bulb produces more lumens (i.e. more light), it also requires more electricity but the most effective bulb is clearly the LED.
