If you want to install short lived fittings that have to be replaced

In some cases I do... if they meet the spec I needed. The last time I
did I would be surprised if you could find an alternative re-lampable
option that would.

Even if I only get a 5th of the 40K hours average life advertised, that
will likely be decades in the application for which I chose them, so at
£13 a pop that is fine by me. Cheapest rarely means best.

I don't.

Best you stick to carbon arc filament...

those are 2 different technologies, neither of which I have any reason to use on any great scale. Filaments are still in use in niche apps here.

Of course the comparison is invalid but hey


Also work keeping in mind that in lots of commercial situations
the costs of re-lamping and replacing are similar due to the H&S
brigade insisting that scaffolding be used to reach high fittings
etc.

not relevant to diyers or the general public at home.

Have you been attending the harry school of comprehension? I thought the
"lots of commercial situations" caveat would pretty much eliminate
domestic and DIY from consideration in relation to the point, and yet still?

yet still it's irrelevant to what we're discussing, which is choice of luminaires at home.
