Assuming your lamps are bright enough, then you could always mix up some

your CFLs to adjust the colouration to your own taste.

Problem with these lamps is often holes in the spectrum which a filter
can't really cure. And they're dim enough already. ;-)

For the curious, the non-believers, and the "I need a new geek toy" set
there's a very inexpensive "student" spectrometer that makes it really
easy to see just how discrete the spectra is (are?) on many florescent
lamps.

It's kind of flimsy (vacuum-formed plastic shell) but the damned thing
really works. Quite interesting (Must. Resist. "Eye-opening") to
compare a narrow CFL spectrum to a white LED.

Don't know of a UK source, unfortunately.
