Energy Efficient Light Bulbs Facts

What is an energy efficient light bulb.

Energy efficient light bulbs facts.

The most energy efficient light bulbs are compact fluorescent light bulbs or cfls and led bulbs. 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. Energy efficient light bulbs such as led and fluorescent outlive by more than 12 times the conventional incandescent ones. Contrary to common belief wattage isn t an indication of brightness but a measurement of how much energy the bulb draws.

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. The energy saving is so significant that if every household in the. Energy savings with cfls compact fluorescent bulbs use about 90 percent less energy than incandescent bulbs energy star reports. Leds emit very little heat.

Compared to traditional incandescents energy efficient lightbulbs such as halogen incandescents compact fluorescent lamps cfls and light emitting diodes leds have the following advantages. Cfls have a lifespan approaching to10 000 hours while leds will serve you for 25 000 to 50 000 hours before breaking down. Energy star certified light bulbs. Typically use about 25 80 less energy than traditional incandescents saving you money can last 3 25.

Leds use diodes to produce light. 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. In comparison incandescent bulbs release 90 of their energy as heat and cfls release about 80 of their energy as heat. In addition they user around a fifth of the energy used from incandescent bulbs so at the end they result in significant savings.

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