Lighting Myth

I heard that Discovery Channel's MythBusters did a bit on their show this week about lighting, and whether it pays to keep the lights on when running down to the coffee machine, or turning them off each time. Unfortunately, I didn't see the episode and I can't find the data they generated. I did, however, find piles of posts on their message boards all about their findings.

What I'm told is that you should just get rid of your incandescent bulbs (duh), that you should turn off your fluorescents if you're leaving for more than 23 seconds, and that LEDs don't burn out. All 3 of those statements require some qualification, but I'll leave that research up to you unless you ask for more info - which I'd be happy to dig up.

I've been shopping for more general-use LEDs and haven't come up with much. I wrote about them for Christmas Lights, and still love them. You can buy a few different varieties for general use, but you can't get the candlepower or lumens you can with CFLs anywhere in the affordable range. Give 'em time. If you want to see what's out there, search for "warm LED light" on Ebay.

So buy the penny-pincher on your list a few warm-colored (make sure) compact fluorescents for Christmas, and plan to buy them some LEDs in a year or two.
