Dimmable LED electronics
I need to buy one BA15D to replace a burned out Halogen 120V 75W garage
stair light that is attached to the side wall. It doesn't need to be brightly lit as it's a short set of open steps and it's not on a dimmer so I don't care about the wattage all that much. But I was told by someone dimmable LEDs are more robust than non dimmable LEDs. Amazon has three kinds of 12V BA15D LEDs with respect to dimmability [1] some don't say if they are dimmable https://www.amazon.com/BA15D-Bayonet.../dp/B07GKCC76Q [2] some say they're not dimmable https://www.amazon.com/BA15D-AC100V-.../dp/B07RFFZ914 [3] some say they are dimmable https://www.amazon.com/Equivalent-40.../dp/B08DP6CWNS What makes an LED dimmable anyway? Is it just advertising hype? Or does the electronics have something special I can actually see inside? |

And if it dims, you said you don't need much light. Amazon has three kinds of 12V BA15D LEDs with respect to dimmability None of these are listed as 12V. But if they were they wouldn't owk in your fixture. Also note that all are different wattages, so they are different bulbs and maybe different in dimmabiliity. You know you can ask questions on the Amazon Q&A section. You can ask if it's really dimmable.

My house is about a year and a half old and the builder put in all LED bulbs. So far I've had 8 or 9 of them fail. I have one of the failed bulbs here on my desk. It's an Ecosmart model B7A19A60WU11 9W 800 Lumens 173ma 2700K Made in China. I'm guessing my builder buys them by the warehouse. Is there a brand that's better than others? Back in the 60's you could mostly trust Sylvania, GE, and Westinghouse. What do we have now? There seems to be a million brand names, all made in China, possibly in the same factory. |

@fmguy.com says... hose things have several/many LEDs, right? So if they all stopped at once, it's not the leds themselves but some part, supplying power to them, that they share. Yes, there are many single LEDs in one bulb or tube. I have not taken a tube apart, butthe screw 60 watt replacement has about a dozen LEDs in them I think they are in a series/parallel arangement electrically. I am sure the tubes are the same way or they may all be in series like the old Christmas tree lights. Depending on how they are made and color the individual LRD usually take from just under 1 volt to about 3 volts for normal brightness. They are actually current dependent and not voltage dependent as long as they have that 1 to 3 volts across them. |

@fmguy.com says... I'm only using 2 LED bulbs, shaped like regular light bulbs. They are very bright. One is in a lamp I keep knocking over, and it doesn't break. Doesn't seem like it might. They seem more rugged than the traditional glass lightbulb. Several that I have opened up are some kind of plastic and not glass. Almost impossiable to break. You can throw them on the cement sidewalk and they will not break. Probably will still work. |

I think my lifetime total must be 5-10 broken incandescents, I can remember 2 CFLs broken when I dropped the drop light. LEDs don't care how careless I get, none broken so far. -- Dan Espen |

I see that Amazon has those Feit bulbs that Scott mentioned. A 10-pack is only $24 and with free shipping that works out pretty well. I found some that are 5000K, which I greatly prefer to the yellowish 2700K that are supposed to mimic the old style filament bulbs. Trump likes the yellowish bulbs because he can use less face paint, but I'd rather be able to see clearly. |

I've got Feit, Philips, Noma, Sunbeam, Ikea and TCP with virtually no failures. Not impressed with the Ikeas - and they were not dimmable - Had some Luminus - bad luck with them. Over 60 TCPs at the church - one dead out of the box - no failures in use. |
