I don't know about everyone else, but when I buy lightbulbs, it's usually because one has burned out and I just need to replace it. Sure, I'll probably buy a 4-pack of the bulbs to have for the next time any burn out. But other than when we first move into a home, we don't buy all the bulbs in the house at the same time.
That means, if one bulb out of a 3-, 4-, or 5-bulb fixture needs to be replaced, I get a duplicate of the bulbs already in the fixture. Otherwise the fixture looks bad with a mix of bulbs for months to a year-plus until the others need replacing.
Also, the new "swirly" bulbs look stupid in a fixture where the bulb is visible.
Also, some people will always spend $1 now and $1 next week and $1 the week after that and the week after that, rather than pay $2 now and $2 next year.
In my experience buying bulbs, it's more like spend $2 now and then $2 in six months to a year later. Or spend $15 bucks now to replace all the bulbs in the fixture now, and then probably never again.* The annual energy costs are effectively invisible.
I'm not opposed to the longer-lasting bulbs, at all. It's just that bulbs aren't something I think about much, and I don't naturally think of them as an "investment" -- they're quick fix purchases. There may be "normal-looking" new bulbs, (vice the swirly kind) that are available, but again, bulbs aren't something I research into. I just pick up a pack when I need to when I'm out shopping for other stuff.
* Edit: I just looked up the cost of 60-watt bulbs at Target.
4-pack of normal bulbs = $8.19
4-pack of CFL bulbs = $12.48
Hmmm. The CFL bulbs use only 13 watts of energy -- only 21% of the normal bulbs. OK, maybe I should start getting these for concealed-bulb fixtures. But we have a lot of fixtures with exposed bulbs. Hmmm, again.
This is the most research I've done for light bulbs ever.
