Yeah, no problem agreeing with that.

I have replaced some totally-enclosed fixtures with more open ones just so I can use modern bulbs in them. Even the horrid CFLs we have need open enclosures to keep working reliably indoors.

Our experience here with CFLs differs considerably from the "reliable" descriptions of the quoted article. They've simply been terrible, with very short lifespans of only 1-3 years. Cheapies as well as pricies.

Incandescents last 10-20 years for us, and the "wasted heat" from them is not at all wasted in this climate, at least not from the indoor fixtures.

Dunno yet about LED lifespans. Outdoors, in the winter, the LEDs win hands down in the totally enclosed "jam jar" fixtures. But come summer heat, we'll see how they do.
