How Do Led Lights Compared To Halogen

Do cfl or led bulbs last longer.

How do led lights compared to halogen.

Led technology is by far the most energy efficient of the two. Halogen lights are much cheaper to purchase but the lifespan of an led light is about 25 50 times longer. The thing that makes them comparable to the led is the fact that they can operate in environments where the temperature is high which is something the led can t. Light color or color temperature is measured using the kelvin scale.

Leds are available in warm colors low k to match the yellowish light of incandescent bulbs but you can also choose cooler colors high k with whiter or bluer light. Comparison between led and halogen lights. There is no risk of burns as with halogen lamps. That looks at the amount of power emitted as light compared to the amount of electrical power drawn.

Available in standard edison bases these bulbs are used as area lighting for rooms porches reading lamps accent lamps hallways and low light applications where lights remain on for extended periods. Led lights are typically more attractive potentially giving the newer technology a subjective edge as well. An average led light uses 8 watts of power while halogen lights average about 90 watts. Users will also save costs on power consumption.

Although led technology for use in bulbs has not been on the market for long the lifespan estimates for the new technology are astounding and leave cfl and incandescents with little to show for in comparison. Led lighting comparison. The halogen bulbs are less effective in terms of longevity when compared with the led though they are a better option compared to the traditional lighting. Longterm users of led s will save money on the amount of replacements that need to be purchased.

Now that the incandescent light bulb is pretty much a thing of the past you must choose between led light emitting diode cfl compact fluorescent and halogen bulbs to light your home. Leds produce the longest lasting most energy efficient lighting available today. As a positive side effect of the low energy consumption most led lamps only get hand hot. The energy savings and much longer lifespan of led s compared to halogen lamps have been described above.

A bulb s ability to emit light relative to its power draw is referred to as its luminous efficiency. Passing a current through the junction of these two materials combines the electrons with. A semiconductor rich in electrons and a semiconductor rich in holes are used to create an led. Halogen light bulbs have a luminous efficiency of only 2 4.
