Things I've learned the hard way (some of which are now mentioned in the article):

-- Not all brands are alike. I have tended to choose name brands, but it's not a guarantee.

-- The bulbs excel in open air applications where they burn constantly for a long time.

Enclosing them in a light fixture where they get hot screws up their circuitry, and they go out much sooner. I learned this only recently. Apparently there are bulbs designed for this. I haven't found them yet, or they aren't clearly marked. A workaround is using lower-watt bulbs, but I don't have enough data in on this since I just started doing this.

Before this I assumed three 23-watt bulbs in a fixture that was designed to hold three 60-watt incandescents was workable. It isn't.

-- Recycling bulbs will mean a trip somewhere. If you have a lot of them--and I do--it means a trip to the main recycling center. Some local hardware stores are willing to take your old bulbs (yay!) but my local one will only take five at once (bugger.) The internet will tell you where you can recycle in your area.

-- Prices have come down considerably, so even a shitty bulb isn't that big of a hit in the pocketbook. But what this means is that we stand a good chance of ending up with millions of light bulbs that don't last any longer or cost any more than incandescent ones, but are toxic waste. The only plus is that they still generate more light for less energy.
