Anywhere from one to three

My house is mostly LED, though I do have a few fluorescents (CFL and linear) and incandescents in use. The fluorescents are in medium/long use and incandescents in short use places.

This is unrelated, but you should move this to the Wanted section under advertisements.

One 36W T8 tube that lasted ~10 years, some days whole day on till the night, some days not used at all, probably somewhere around 20..25K hours in all - Osram Energy Saver L36W/765 made in China ~2014

One 8W LED filament lamp that lasted a month of D2D in my use, it was found with a fitting and have done unknown number of hours before - Eurolux 8W/2200K A60 made in China ~2020s

Haha, when I saw the topic I thought it said 'JB HI-FI', which is a super popular electronics shop in Australia lol.

I have never kept count .lol.
But can say its usually multiple linear fluorescents - as I use them for both my fishtanks & houseplants(so daily 8-10 hours use), plus parts of the house are fluorescent.
Plus multiple standard screw-in incandescent and/or CFL lamps.
Then if you add Christmas lights during holiday season, there's always a number of little bulbs - both LED and incandescent.

Oh and seems its not uncommon to replace a ballast or 2 a year as well.

Yeah they have some pretty good stuff.

I eventually plan to get the blurryface album on CD, or maybe just find a download for it.

I have a fair collection of CD's (the majority of which were bought cheap at thrift-stores/garage-sales/store closings)
There's some old vinyl's (mostly stuff my parents got(so its technically theirs) when I was a kid) which I almost never listen to.
There's a bunch of MP3's on the computer too.

Main system is in the bedroom, receiver is a Pioneer(surround-sound), there's also a Yamaha soundfield processor (just used for extra speakers & its various effects)
A couple CD players: Pioneer 12-disc(which something went wrong with so I can't use anymore) Technics (which had quit working but just needed a belt so an easy fix)
A Pioneer cassette deck (rarely used), A Technics EQ, a HD-Radio tuner...
Various brands: Blu-ray player, DVD player, Laserdisc player(not sure it even works anymore), HD-DVD player, VCR, Minidisc player(dead)
(and a couple other random things too)
Computer is connected to the system too so I can play MP3's/etc on the stereo.

Most of those units were bought cheap at thrift stores or garage sales, but a few like the Yamaha, DVD, Blu-ray & HD-Radio were new at stores (on either sale or clearance ofcourse)
None of it is high-end stuff, but its not bottom-end junk either.

Main front speakers are homebuilt(ie: cheap cobbled together junk) secondary front speakers are Pioneer(nothing special)
Main ear speakers are Sony & secondary are homebuilt(neither is anything special)
Main & secondary center speakers are Jensen.
Subwoofer is homebuilt & has a Buttkicker amp.

The system can certainly crank(and pound out some bass) far louder than I'd ever need... (but nothing to the level of one of my neighbors who has a true hi-fi setup)
There's also a Pioneer surround receiver in the livingroom & a technics surround receiver(which doesn't always work quite right) in the familyroom. (don't remember what speakers are on either, but they're just common stuff)

I know some people switch between stereo & surround mode for music & movies, I just leave it in surround mode for everything.

Oh and there's also cables & a splitter-unit so I can play music from the bedroom system & listen on the ones in other rooms...

I've worn out a couple CD players over the years because I used them allot. Used to be if I was home (and awake), the stereo was on.

I would say maybe 1-4 per year. I mostly use fluorescent, low voltage halogens and some LEDs. I try to use light sources the way intended so for an example fluorescent lamps in places where they will do long hours in single switch on while LED in locations where switching on and off happens more frequently.

Well I treated myself to a new power amplifier

The Chord SPM1000b and Parasound ZampV3's have been replaced with a Musical Fidelity M6X250.5!
A massive multi-channel power amp which tips the scales at over 30kg!!!

Sounds fantastic! Is it better for stereo music but comes into it's own when watching movies and playing games!
All I can say is phwoar!

My poor Tannoy TS10 subwoofer blewup a few months ago so I replaced that with an REL HT/1003 MKII which is an absolute monster!
I don't need it when listening to music as the PROAC D2's have more than enough low end grunt but when watching movies it does a really good job in the LFE role!
