We have a few of these in our house. I keep them for green reasons, but don’t particularly like them.
As has been pointed out elsewhere, the color temperature of the bulbs you can actually buy at the store is poor, tending to be greenish or yellowish. The ones available in the store don’t work with reostats. Or in the cold. And they’re a bit flickery. They don’t look especially good in recessed lighting applications. And they are useless for lamps whose shades clip to the bulb.
Yes, I know that after research on the web I can get different color temperatures, and can get different bulbs that might work better in specific applications, including cold and recessed lighting. I, however, am less than thrilled at the prospect of having to do research, and place a catalog order, in order to buy such a mundane object. I also don’t reliosh the thought of warehousing them for years because I had to buy a huge number in order to make the shipping cost reasonable.
Now, in today’s Globe, it sounds as if when one breaks, you might as well break out your haz-mat suit. Doubtless a little alarmist, but still, the worst consequence of a broken tungsten bulb is a glass splinter.
They certainly have a ways to go before these things are consumer-friendly.
