From the “Community Grumbling” department: Last week, the New York Times’ Green, Inc. blog posted a short item on the ongoing debates of energy efficiency/chilly green alien light CFLs versus energy wasting incandescents which have a better range of color temperatures and wattage versatility. It quoted a number of reader comments from previous posts on the subject. 
That sparked another round of comments so, today, the blog featured a Q and A with self-proclaimed “CFL Advocate” Michael Siminovitch, a professor and director of the California Lighting Technology Center at the University of California, Davis. The topic is relevant and timely, as incandescent’s prognosis is terminal.
Consumers, the piece asserts, rarely go to Home Depot thinking about energy efficiency. Instead, if they’ve got a dimmable fixture in the wall, they’re going to want a bulb which dims. If you plug a conventional curlicue CFL into a dimmable outlet, it will not light. A consumer looking for a bulb for a lamp by which they read at night, is not going to want a bulb which emits the same light as their office light fixture does. (See mine below as an example of this)
Check out what Siminovitch says is the delay in bringing better CFLs to a wider market and what we can expect for the future, here.
A quick recap of things to come for the bulb
of yesteryear: Brazil and Argentina began to phase them out in 2005, Ireland and Switzerland will follow suit in 2009, the UK in 2011, Canada the following year, and us Yankees will kiss them goodbye between 2012 and 2014.
There’s a bit of innovation under way, though, to extend the incandescent’s lifespan: Two years ago, General Electric announced the company was working on a high efficiency incandescent (HEI) which would be four times as efficient as a current incandescent lamp.
Stay tuned.
