As some of my long-time readers may know, I have never been a truly ardent fan of compact fluorescent lighting (CFL). Why?
1. Probably most importantly to me, in my experience with CFLs, I haven’t been satisfied with their start-up characteristics. They take a little while to “warm up” to full luminescence, and until then, the light seems very sickly to me. It actually makes me a bit nauseous. I know that better quality (i.e., more costly) CFLs perform better than cheaper generics, but even CFLs from General Electric (NYSE: GE) that I’ve bought still don’t turn on as well as I have come to expect from four decades of living with incandescents.
2. Except for some new (and considerably more expensive) products, CFLs generally don’t work with dimmers. I once found this out the hard way — snap, crackle, pop. I don’t know about you, but a lot of the light circuits in my house are on dimmers, and as a result I continue to run incandescents on them.
3. It is becoming more well-known that CFLs contain mercury, and hence their disposal is a real issue. Even worse, if one were to break, the release of mercury represents a significant risk — at best a big clean-up nuisance.
4. CFLs aren’t cheap. True, CFL prices are coming down to become closer to the levels of old/inefficient incandescents, but they are still substantially more costly. For lights that are rarely used, the extra investment doesn’t make much sense to me, as the energy actually saved is small.
So, I’ve been eagerly awaiting the emergence of LED (light-emitting-diode) products for consumer application. I like the quality of LED light, and LEDs don’t have the mercury issue, so it seems like the superior long-term lighting solution.
I’ve been told that household LED lighting is still many years away, but at least some products are trickling into the marketplace. For instance, see EarthLED Lightbulbs, which are available at Think Geek. Clearly, they are still a niche item for the early adopters, as they cost $60-100 per unit, but at least their emergence into the market now puts consumer LED lighting on the gameboard, hopefully on a quicker path of cost reduction as learning curve and scale production effects are achieved.
Since LEDs have virtually infinite lifetimes, in the future, there will no longer be a need to make lamps with removable bulbs in sockets. Savvy marketers out there should begin working to overturn the old paradigm of reusable lamp/disposable bulb, making way for LED lamp fixtures that are inherently designed to capitalize on the unique and compelling advantages offered by LED lighting.
