Criteria | LED (Light emitting diodes) | CFL (Compact Fluorescent Lamp) |
|  |  |
Description | LED bulbs are cool to the touch as most of the energy is released as light. In CFL, most of the energy is released as heat instead of light. Thus, CFL bulbs consume more energy than LED bulbs |
Initial cost per bulb | ~$5 | ~$6 |
Relative power consumption for the same amount of brightness | 
| |
Annual Energy cost | ~$1.50 | ~$2.60 |
Typical lifespan of bulb | 15,000 hours | 8,000 hours |
Number of light bulbs needed for 15,000 hours of use | 
|
|
Total purchase and electricity cost for 15,000 hours of similar light output | ~$26 | ~$48 |
*The bulbs have equivalent brightness (700 lumens)
