It means I can make side by side comparison. The LED tubes provide a

You do realise there is a vast range of florry tubes available? ie, not
just white and warm white? Of course, as with most things, decent tubes
are more expensive than the ones which come with the fittings.

I am very aware of that, this sub-thread was about efficiency rather
than colour after Bill's comment. My post about colour was intending to
be a throw away comment when making the comparison.

The old tubes were marked Sylvania, hardly a no-name brand.

One thing I didn't mention is that LED tube replacements claim a 270
degree output as opposed to the original at close to 360, hence this
could account for some increase in output when viewing the lamp directly.

There are tri-phosphor tubes on the market that are suitable for
photography etc where light quality is important.

I think you have said this before. I suspect they're expensive? Don't
they also degrade over time?
