Energy Efficient Light Bulbs Facts

Cfls use mercury to cause a phosphor coating on the inside.

Energy efficient light bulbs facts.

The most energy efficient light bulbs are compact fluorescent light bulbs or cfls and led bulbs. What is an energy efficient light bulb. In addition they user around a fifth of the energy used from incandescent bulbs so at the end they result in significant savings. Leds emit very little heat.

Cfls have a lifespan approaching to10 000 hours while leds will serve you for 25 000 to 50 000 hours before breaking down. The lifespan of a led lasts over 60 000 hours compared to the 1 000 hours of a traditional incandescent bulb this saves a lot of energy used to produce and dispose of the bulbs. Energy star certified light bulbs. Leds use diodes to produce light.

Energy efficient light bulbs such as led and fluorescent outlive by more than 12 times the conventional incandescent ones. For incandescents there is an accepted correlation between the watts. Other light bulbs create light using heat which takes a lot more energy than the use of diodes. Contrary to common belief wattage isn t an indication of brightness but a measurement of how much energy the bulb draws.

Typically use about 25 80 less energy than traditional incandescents saving you money can last 3 25. With other types of lighting the light must be reflected to the desired direction and more than half of the light may never leave the fixture. Compared to traditional incandescents energy efficient lightbulbs such as halogen incandescents compact fluorescent lamps cfls and light emitting diodes leds have the following advantages. The energy saving is so significant that if every household in the.

The high initial costs of energy saving light bulbs are balanced out by the fact that these devices can pay for themselves a greatly increased lifespan.
