Who else, I ask you, brings you this much personal experience on the subject of light bulbs?
Last year, reader backwoods conservative observed:
What is recommended for garage doors is rough service bulbs. They have more supports for the filament and therefore do not break so easily. The bulb itself is often made stronger to be less prone to breakage. The information I have is that rough service bulbs are exempt from the new standards and will still be allowed. They are more expensive, but I hear they hold up very well.
I haven’t changed a bulb in the garage-door opener in a decade, and I am loath to start now. That said, a few weeks back the supermarket had a box of off-brand “rough-service” bulbs for a not-unreasonable price — three bucks for four bulbs — and I decided to give them a shot in some other applications.
And in those cases, the results were decidedly meh: the bulbs seem sturdy enough, and design life is no worse than other incandescents, but this particular series is rated at a meager 500 lumens, about a third less than one gets from the usual 60-watt classic. I would have known this, of course, had I bothered to read the actual box; it’s not like this little detail is hidden away.
[T]he hemidemisemiglobe, apparently insufficiently tightened down, yielded to the force of gravity, forcing me into Shard Removal mode. Results: fairly unsightly. On the upside, it’s a hell of a lot brighter in there, and now the freaking CFLs ought to work better, so long as I don’t actually replace the glass.
As it happens, I didn’t have any freaking CFLs in there, as they died entirely too quickly in the fixture with that glass dome in place. When one of the two 60-watt classics died last week, I wearily dragged out the stepladder, ascended to the heights, dismounted both incandescents, and installed two 20-watt CFLs, billed as the equivalent of 75-watters, which were not recommended for this fixture because, um, heat. Let’s see ’em get more than moderately warm without a big glass ball surrounding ’em. Further upside: 2400 lumens instead of 1600. Downside: it’s much easier to see how much the kitchen floor (white tile) needs a good mopping.
