Not so. The light output from CFLs might not be as high as the GLS (I don't
believe that they are) but they give out enough light to prevent us oldies
stumbling, which is what David was saying.

Presumably that's what the manufacturers mean by 'equivalent' then...not
equivelent in light output, just 'bright enough'.

As the discussion is about saving energy, then I see this as broadly
equivalent to turning your heating down, on the basis that 1-2C cooler
is still "warm enough".

It is annoying that the LE bulb manufacturers had to make excessive
claims about equivalence, but then one of the biggest is Philips, who
of course invented "perfect sound, forever" when the first generation
of CD players was launched...
