Energy Efficient Light Bulbs

Compared to traditional incandescents energy efficient lightbulbs such as halogen incandescents compact fluorescent lamps cfls and light emitting diodes leds have the following advantages.
Energy efficient light bulbs. When first developed leds were limited to single bulb use in applications such as instrument panels electronics pen lights and more recently strings of indoor and outdoor christmas lights. What is an energy efficient light bulb. This is just a simple somewhat scientific test of various types and wattages of light bulbs with some surprising results. Leds light emitting diodes are solid light bulbs that are extremely energy efficient.
Leds are the most energy efficient of the light bulbs available on the market and they also have a considerably longer lifespan than both cfls and incandescent light bulbs. Incandescent bulbs and halogen bulbs have the highest wattage making them less energy efficient choices. Cfls use mercury to cause a phosphor coating on the inside. Typically use about 25 80 less energy than traditional incandescents saving you money.
Cfl bulbs use fewer watts but led bulbs are the real winner in energy efficiency an 8 or 9 watt led bulb emits as much light as a 60 watt incandescent bulb. The most energy efficient light bulbs are compact fluorescent light bulbs or cfls and led bulbs.
