This is why I want to see the exact terms of the ban in the UK and rest
of the EU. If rough service bulbs are exempt, then there is no problem at

It's no problem at all. The bulb is going to last a long time used as a
series limiter, and aanyway it problaby saves its cost many times over
every time I use it.

Right... So just what is the point of this ban? :-)

Maybe, maybe not. I think it's simpler to just go and ask for the rough
service bulb. After that, what I do with it is my business and nobody
need know :-)

And what on earth is the point of 'no more than 2 bulbs per box', other
than to ensure the use of excessive packaging which will need to be
recylced. I thought they were trying to cut down waste, not increase it...
Is it similar to that ridiculous law that you can only buy Aspirin
tablets in boxes of 16 (or 32 from a registers pharmacy)? The idea behind
that was you couldn't buy enough to fatally overdose on. But if I was
daft enough to want to commit suicide that way (and I will assure you I
am not), I would have the sense to visit several shops to get enough pills...

Well, considiering I saw new _carbon filament_ bulbs advertised on a web
site quite recently, I suspect that rough serve bulbs will be around for
quite some time..

True, and I guess for much the same reasons. There are applications where
there is no alternative to lead/tin solder.
