LED Bulb in High-Vibration Environment

The garage door opener just ate another rough-duty bulb, so let’s see how a $7 LED bulb fares:

It has no external heatsink fins and the color temperature looks just like the old-school incandescent bulb it’s replacing, so they’re getting a clue about what’s acceptable to ordinary folks.

That’s equivalent to a 60 W incandescent bulb, too, at least according to the package:

I love the “Return the package and reciept for replacement or money back” part…

    My garden-variety Craftsman garage door operator uses an ordinary incandescent bulb in the same location and it’s been there for years and years. What causes your GDO to vibrate so much?

      Ol’ Gene suspended it from two angle-iron brackets that extend four feet up to the bottom of the garage roof trusses: it can shimmy side-to-side and tilt front-to-back. It would be bolted directly to the ceiling of a normal garage, where it wouldn’t move at all… but this ain’t no normal garage!

        two angle-iron brackets

        I’d be worried about other problems with the opener, too. Triangulation is your friend. HD has galvanized perf angle that comes in handy for such projects, though I like plain angle from the steel supplier for 1/3rd the cost (of plain from HD). Helps to have a lumber rack on the pickup. They’ll cut 20′ lengths to something portable, charge unknown.

        Haven’t tried LED bulbs in rough service yet. I have a sacrificial CFL in the occasionally used trouble light.

        BTW, applying heat worked on the disc harrow axle nut. Had to use the preheat burner from the cutting torch to get enough heat. Thanks for the tip.

          Triangulation is your friend.

          Aye, but it’s been that way for nigh onto half a century and I’m loathe to putz with it.

          The openers ate bulbs at the rate of one every few years and Gene left a box in the basement, sooo…

          What, me worry? [grin]

          Smoke wrench FTW!

    A neighbor was losing an incandescent bulb every 6 months. He resolved the issue by bolting a single-tube 4-foot fluorescent fixture to the horizontal underside of the trusses and then screwed a 2-prong adapter into the GDO socket, then plugging in the fixture cord.

    Problem solved, and more light besides.

    The single tube fixture is along the vehicle axis in the center of the garage, there’s a second fixture (a 2-tube) over the workbench that’s along the wall.

    BTW there’s an ongoing thread on a mailing list that I’m on about how the CFLs and the LED bulbs are raising the noise level at radio sites. Don’t be surprised if your HF reception goes to pot over the next few years.

      [shudder]

      I should do that… but gimmick up an earth ground of some quasi-legit status. [grin]

      Haven’t done HF in a loooong time; the lightning crater in the garage apron put me off outdoor antennas in a big way.

    The fixture – Big Orange (home depot) no longer sells it – had a two prong power cable. .

    And I totally agree with the “shudder” – there’s a reason the green wire is called a Safety Ground.

      Kudos on the wiring article…

      I’d add a note that you should always measure the voltage on every conductor in a “dead” box before doing anything else, because You Never Know.

    “Return the package and receipt for replacement or money back”. I interpret that as, “buy a new one and return the old one to the store in the new one’s package with the new one’s receipt so you don’t have the hassle of dealing with the manufacturer.”

      Well played, sir!

      I think of that as being somewhat underhanded, but, given the sincerity of the original warranty, it’s hard to argue with the logic… [sigh]

      • #11 by Jason Doege on 2015-04-01 - 10:28

        Underhanded, yes, but I only use the power for good. That is, I only use it for infant mortality cases which even the better LED bulbs seems to suffer from.

        • #12 by Ed on 2015-04-01 - 11:39

          infant mortality cases

          Those are the failures that make you wonder how much testing happens near the end of the production line, just before the packaging machinery. Probably little-to-none, because they’ve baked quality into the manufacturing process…

          But, mostly, the stuff works, doesn’t cost much, and we’re kvetching about the outliers.

        • #13 by david on 2015-04-02 - 17:28

          If for no other reason than because by the time you get to any non-infant mortality, they will undoubtedly no longer make any similarly-packaged products… Ahh, progress!
