5826RE: [hreg] CFL lifespan, CFL embodied energy
- Mar 12, 2007
A couple comments...
1) on the “energy embodied” comment, I note that when CFL’s first came out, a lot of them were those quad shaped things that plugged into the ballast, so that you only replaced the bulb part and not the ballast when they burned out. Those don’t seem to have become very popular with consumers, and I don’t see them in the stores now. I suspect that is because of varying brands/incompatibilities making it confusing/hassle for consumers, and/or the form factor vs. spiral. Maybe someone has insight into this. But I think that if the ballasts were made more robust, and the plug-in design were used, maybe it would address my concerns about premature burnout (if that is the ballast—I don’t even know that, though), and it would also perhaps reduce total “energy embodied”.
2) Leaving CFL’s “on” might be a good idea for longevity, but if one needs a bulb in an intermittent use area, then clearly leaving it on 24x7 will negate the energy savings. If some CFLs are sensitive to on/off switching as you and some others have commented, then we need a way to determine which brands are tolerant of that behavior.
