What's the longest lasting lamp in your house?
For me, It's the Indonesian Philips incandescent in our laundry. It refuses to die despite being used almost every day!

A generic brand LED filament lamp that's going on 7 years despite heavy use.

As in my signature, my little 3 watt Energetic mini globe LED, fast approaching 50,000 hours at its current 47,738!  8)
It’s connected to my outside lighting circuit and serves as a nightlight in my bathroom so you don’t have to be blinded by the bathrooms main lighting if you need the loo at 3 in the morning!
As a bonus it’s not lost it’s warm white colour and it’s as bright as it was when it went in at 0 hours!  8)

I wouldn’t be surprised if the two incandescents in the attic are the originals from the 70s. Don’t know what brand they are. They don’t get turned on often though.

Also the bulb in the living room ceiling fan could well be 70s as well.

It has to be the 28W 2D fixture in our bathroom; it gets switched on and off multiple times daily, and it's still going strong after 11 years on the original lamp  ;D

Probably a TCP CFL under the stairs.  Only used intermittently, so it probably doesn't have a ton of hours, but I think almost every other fixture in the house has been replaced in the time that CFL has been there.

a pair of 1980s vintage Sylvania GTE F40T12 CW that I use in a shoplight fixture.  Love it.  Also have some GE F40T12 from the 1980s as well, they too are doing great but showing signs of the long sock which I love about them.

In 2010 I installed LED GU10 lamps all around my home, naturally of my own design made by Sylvania.  All are still running after precisely 12 years service with no discernable depreciation of output.

These are outlived only by three FHE-T5 fluorescents that have been going almost 20 years despite daily use in the kitchen with multiple switchings per day  I am sure they could do another 20 years thanks to their ultrasoft cathode pre-heating on an outstanding Israeli-made Clalight Uniqtronic ballast.  But since the same light level can now be achieved for 50% reduced energy consumption and with CRI increased from Ra82 to Ra95, plus considerably reduced EMF which is very important for our health, I am planning to retire them and change to LED filament T5.  Those will probably last well into my retirement in another 20 years time!  I am not certain though that the remote LED drivers will survive so long.

I've replaced all the lamps in my house at some point but one, a GE 65w BR30 incandescent, original to my house which was built in the 2000s, that gets rarely used.

Longest lasting hour-wise are a pair of Feit 12.2w BR30 LEDs in 5000K. They were installed in early 2019 and are still going strong, running dusk to dawn.

There is a 130V, 60W Abco Light Bulb that I recently found in the fixture of our outdoor balcony. It's literally original to the development from 1982. I was beyond shocked, that it was still going, and that the base was uncorroded. They just don't make things like that anymore.

Probably the incandescent lamps in the ceiling fixture upstairs, they've been going strong for 20 years!

It's gotta be the GE preheat f15 t8 fluorescent above my kitchen sink. it's older than me, and has been going every day since I was born (15 years ago) it could have been there since the early 80's though since that's when the house was built. still going strong to this day and is used daily!

I used to have a bathroom vanity light with five candelabra bulbs and three of them lasted over 15 years at a couple hours a day. They were on an old rotary dimmer so you had to turn them on slowly from 0%.

All of them had major sagging/drooping of the filaments between supports like a limp piece of string, and the top of the bulbs were blackened.

I feel like that dimmer gave them a massive boost in life span. If you touch the knob just right you could get it so dim that the filament barely glowed, and you could see the hot spots that glowed slightly brighter.

Eventually the light fixture was replaced and the bulbs were gone.

There was also a preheat CFL from the early '90s in a seldom used closet that I took with me when I moved out. I left and this really funky looking LED COB thing in its place.
