Energy Efficient Light Bulbs Facts

Energy star certified light bulbs.

Energy efficient light bulbs facts.

For incandescents there is an accepted correlation between the watts. In addition they user around a fifth of the energy used from incandescent bulbs so at the end they result in significant savings. Cfls have a lifespan approaching to10 000 hours while leds will serve you for 25 000 to 50 000 hours before breaking down. Energy savings with cfls compact fluorescent bulbs use about 90 percent less energy than incandescent bulbs energy star reports.

In comparison incandescent bulbs release 90 of their energy as heat and cfls release about 80 of their energy as heat. 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. Energy efficient light bulbs such as led and fluorescent outlive by more than 12 times the conventional incandescent ones.

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 use mercury to cause a phosphor coating on the inside. Use up to 90 less energy than standard bulbs last at least 15 times longer and saves about 50 in electricity costs over its lifetime meet strict quality and efficiency standards that are tested by accredited labs and certified by a third party. Leds emit very little heat.

Leds use diodes to produce light. Contrary to common belief wattage isn t an indication of brightness but a measurement of how much energy the bulb draws. The most energy efficient light bulbs are compact fluorescent light bulbs or cfls and led bulbs. What is an energy efficient light bulb.

Typically use about 25 80 less energy than traditional incandescents saving you money can last 3 25.
