LED Versus Halogen Lighting

There are several advantages associated with both LED (light-emitting diode) and halogen light bulbs. In terms of efficiency, LED lights are undoubtedly more efficient than halogen lights. Perhaps the only benefit that halogen lights have over LED lights is a lower initial purchase cost.

How They Work

Probably the biggest difference between LED lights and halogen lights is how they function. LED lights produce light when an electrical current is run in an arc pattern between two electrodes. Halogen lights produce light by heating up a tungsten filament.


Overall, LED lights will last much longer than traditional halogen lights. Halogen lights are typically rated to last for anywhere between 2,000 and 6,000 hours or two to three times as long as incandescent light bulbs. According to Eartheasy.com, an LED light bulb can last an upwards of 100 times as long as an incandescent light bulb.


LED lighting is considered to be “energy-efficient lighting.” This means that the light they emit is produced by using small amounts of power. Halogen lights are merely slightly modified incandescent bulbs; a great deal of the energy used to light a halogen light bulb is given off in the form of heat. .


Halogen light bulbs contain traces of halogen in their fill gas. The halogen helps deposit evaporated tungsten back to the filament which makes the bulb last a little longer. LED lights are small but can be clustered together to broaden their applications.


Halogen light bulbs cost much less than LED light bulbs. LED light bulbs have a very high production cost which contributes to their high price at the checkout counter. However, because of their long life and high-energy efficiency, the initial cost of installing an LED light bulb will be offset by the amount of energy that is saved by the consumer in the long run.
