I will note one thing about CFLs vs. incandescents. CFLs run much cooler. This makes a noticeable difference in the indoor temperature in the summer; especially if you don't have air conditioning. Also, I notice the guy focused on short uses of the bulbs. The temperature issue is more likely to come during long uses. I wonder how much effect that has on air conditioning costs in summer and heating costs in the winter, and do they cancel out? That would be kind of hard to study.
Oh, and as regards his rant about how long it takes a CFL to come up to full brightness. I suspect my father would've found that an advantage. My father hated bright lights first thing in the mornings. Come to think of it, I'm not too fond of them either. A CFL coming on dim would suit him just fine, and by the time it came up to full brightness, his eyes would've had time to adjust.
Also, how flinking bright do you need lights in places like closets to be? Aside from walk-in closets that could double as rooms that is. My answer to that one is bright enough to be able to find stuff, but not necessarily bright enough for reading. So, a relatively low power bulb should suffice. At that point, I think it would be worthwhile to put LED bulbs in those locations where the light is unlikely to be on for any great period of time. (Also, that energy auditor is an idiot).
I got my first CFL about 20 years ago when I was living in a studio apartment. I made the decision because I'd gotten sick of replacing the incandescent bulb every few weeks. Apparently there was enough vibration transmitted through the building to break the filaments on a regular basis even in relatively new bulbs. That bulb lasted me over 15 years before had to replace it and I had it on for hours/day.
I would add that any bulb that's only on for a few seconds a couple of times/week should last for years between purchases. It's also not going to make a significant contribution to the electric bill. I do wonder though, if that rapid cycling set up shortened the lives of the tested CFLs more than the normal usage of a closet light would. I remember reading about the effects of turning fluorescent lights on and off on the lifespan of the bulbs years before I ever heard of CFLs. The article in question recommended not turning them off if you expected to need them again in some minimum time period. Alas, I don't remember what that period was.
