LEDs vs. Incandescent Light Bulbs: The Chocolate Bunny Test


Comparing the relative heat energy output of LED and incandescent lighting

Light-emitting diodes were introduced in 1962 and only emitted a low-intensity red light. Today, LEDs are used for automobile and aviation lighting as well as traffic signals, domestic appliances, and in a growing number of other devices.

LEDs offer more benefits than incandescent light bulbs, such as longer lifespan, more durability, increased reliability, smaller size, and higher energy efficiency.



The average lifespan of an incandescent light bulb is 1,200 hours, whereas an LED typically lasts for 50,000 hours.



While neither contain toxic mercury, a LED emits 451 pounds CO2/year and incandescent bulbs emit 4500 pounds CO2/year. More important to the Chocolate Bunny Test, LEDs require a fraction as many watts per lumen, and they emit 3.4 btu's/hour of heat energy. In comparison, an incandescent bulb emits 85 btu's/hour, way less friendly to chocolate bunnies.



Score one more for LEDs!
