Apart from a few, rarely used, lamps that have yet to be changed, I have
long converted everything to LED.

Me too, except for my bedside lamp which is halogen for colour
rendition. Any comments on reading under a 230V LED spotlight? Would
you go for cool, daylight or warm?

Don't think reading is critical colour temperature wise. Unlike, say,
matching colours.

I thought contrast between the characters and the page was important.
I had a neighbour who had macular degeneration and she found that CFL
lamps made it very difficult to see, likewise sodium lamps outside.

I've got a Lidl LED desk light where you can select warm normal or cool.

Which is better for desk work?

But how an LED appears, colour temperature wise, does not guarantee
continuous spectrum light as you tend to get with halogen.

Yes, this seems to be the case. Do you think price makes a difference
or is it a function of the technology?
