Not only have the energy efficiency pundits predicted the demise of the relatively inefficient incandescent light bulb, but federal legislation had dictated that it must be so (beginning in 2012). But new research promises to give the old favorite a fighting chance, or at least the opportunity to slow its demise. Reflective coatings around the bulb's filament offer the opportunity to reflect a portion of the heat energy that would otherwise be lost back to the filament where it can be transformed to additional light. Other incremental innovations in incandescents are sure to follow. And, light emitting diodes (LEDs) are staged to begin their push into the commercial and residential markets.
It is an interesting time to be a technology watcher. We've recently seen competing audio and video technologies all vying for market dominance. Now, with new flavors of incandescent lighting, CFLs, and LEDs all vying to capture their share, energy efficiency and consumers will ultimately benefit.
