This is more of a rant than a question... Why are there two similar
(but incompatible) lengths of 20W T4 slimline fluorescent tube - the
so-called 'Eterna' variety (as sold by B&Q) which is 578mm between the
ends of the pins, and the 'Standard' variety which is 567mm between
the ends of the pins?

I'm finding it difficult to obtain replacements - at a sensible price
- for the latter size (567mm inclusive) with c colour
temperature. TLC only do 4000K..... grr!

Richard.


Just having a look at most of the sites advertising these. It's cheaper to
buy a whole new fitting than just the lamp on its own. How can that be
viable?

This is the cheapest price I can find online

Any good?
