Haha he's a what you might call a LEDnut got them everywhere in his house except in his shed where he's got 2 ancient fluorescents

What kind of ancient fluorescents?

I was at my cousins place earlier today and had a look at the  fluorescents in his shed I think they date back to the seventies as the fittings are chunky and one has an old style tube and the other has a modern thin tube the old tube is 65 watt warm white I'm not sure about the other

Maybe you could talk him into giving them to you.

Yes maybe I'll have to put on my best sweet voice and ask nicely being a girl has its advantages Lol

That could work   

I actually agree with the OP about this. You can get 2700K CFL and LED retrofit lamps that are pretty much identical to incandescent. I think its just that people don't like change. People refuse to pay over $2 for a lightbulb. So LED manufacturers have to cut massive corners to keep prices down. There is a HUGE difference between the cheap LED lamps and good quality ones. There is just really no advantage to incandescent anymore. I hope the government goes forward with more lighting regulations. Also, incandescent lamps can easily take up more power than a running laptop. I swapped my neighbors porch light with an LED, and I don't think they even noticed until they went a few years without replacing it.

AKA an LEDumbo.

the only use I see now is in ovens. The incandescents can stand temps that would fry CFLs or LEDs. Plus, they are used to keep food warm in display cases or in with special hearing lamps that warm chickens in the coop during winter.

Add to that list any place where you want the absoute best light quality, for minimal eye strain during reading, ie reading lamp

Add to that list any place where you want easily dimmable light, but one that can dim all the way to 0 and keeps light quality through the entire dimming range

Add to that list any place where you want the cheapest and simplest light source, where it does not do much power on hours :
Staircases
Toilets
Air raid shelters
Crawl spaces, attics, rarely used storage areas

Add to that list every single light socket in the house during the winter

Plus, they're better with frequent switching.

Incandescents have to other advantages as well number 1 they give out warmth I like the extra earth from one in winter when its bitterly cold we have central heating plus my reading light gives a little extra 2 they make no RFI now I will admit my radio shack is lit by 2 36 watt preheat fluorescents but if the rest of my house had CFL or LED lighting the extra noise would be horrendas

Yes and it's worse when you have older radioes. I had to replace the CFLs from my room and the surrounding rooms because it interfered with my turntable/radio.

Computer PSU's seem to affect radios too, but there you can tell right away which have proper filtering (so only very minor disturbance) and which are cheap ones that dont (you hear NOTHING but the switching noise of the PSU). Then open it, and indeed, the good one contains all the required coils and capacitors, the cheap one none of that

As in lighting, i notice that Preheat does make noise when starting, but no interference when working after that. How is the interference of Rapid Start ?

I had an analog tv a while back and the garbage disposal downstairs would interfere. Most computers PSUs have filter caps soldered onto the IEC connector pins.
