Are we talking visually impaired here? I think you need to be extra careful,

some cases the colour temperature is so lumpy in the visible spectrum that
many VIPs complain of the light being grainy and causing poor contrast. Far
better I think to use a good make of electronic ballast with conventional
tubes then get specific task lighting in for those who need it.

How does one know the quailty of the elctronic ballast? If I buy a
fl.tube light from say B&Q is the fact it is "modern" some assurance
it is better than much older designs?

No, and in fact unless it explicitly states it contains an electronic
ballast, there is a fair chance it doesn't... You can buy them
separately for retrofitting though.

The fl.fitting in our kitchen is
30 years old :-)

Yours and all the others!
