In the throes of completing the final project for my
Renewable Energy Technology class, I can't help but share a tasty little tidbit. Here's what I've learned about how a high power LED light bulb stacks up against current mainstream light bulb technologies:
A couple of things to keep in mind with this chart:
- Luminous efficacy for an LED bulb is higher than that of a CFL bulb. Believable. But luminous efficacy of an LED bulb at 150 lumens per Watt? Maybe in the lab, but not yet on the shelf at Home Depot.
- Incandescent bulbs and LED bulbs contain no mercury. The 'mercury released' figures assume that the electricity powering the bulb was generated through the burning of coal (a reasonable assumption for Alberta, but not necessarily for other jurisdictions).
More to come on LED's.
