Hi Paul, what has brought you to the conclusion that homes that don't waste energy use a light bulb for 30 seconds or less?Surely location/use of the light is a big consideration? If I graphed the average time my cellar light is on I'm sure that would be very different from the average time my kitchen light was on which would be different from my bedroom light.
I suspect that CFLs perform poorly when used for 30 seconds or less. Which is how most light bulbs are used in a home that does not waste energy.
But it's so much more convenient to just leave every light on in the house so you don't have to look for those handy convenient switches next to every door. Plenty of room for education. For people who just leave lights on everywhere all the time, cfl's "save" lots of energy.
Isn't measuring if CFL are inefficient if on for 30 seconds at a time only half the story?
Then you'll suddenly look like an overnight genius.

I do prefer analog to digital music.

How much 30 second light bulb usage do people actually have?

If I'm in that closet looking for something every morning and again putting it away every night, the bulb should last 4,320 days- 11 years and nine months! That's pretty respectable for a bulb getting abused like that. Sylvania just might cite your test in their next "Treat it badly and still don't buy another bulb for 12 years" ad. What looks like horrible performance from one perspective might be something to be proud of from another perspective.
The harder you work, the luckier you get. This tiny ad brings luck - just not good luck or bad luck.
