The bulbs are/can be but the lamps as a rule are not*.
If you do a side-by-side comparison you can
really see a difference in colour rendition, esp. if the daylight bulb is particularly good (they vary in quality as well as in price) and the conventional light is not good (e.g. CFLs, which generally provide the worst quality of light that we'd commonly pick from). But what actually matters is whether you need that difference - bearing in mind all the work that was done, and is still done, under regular bulbs/tubes for example.
Linked to this is how are the models commonly displayed? It makes no difference if you're using Daylight Bulb XB227 that 100% matches daylight in Northern Europe at 1pm on a summer's day if the model doesn't look just as good under your room lights, or the lights of a competition hall
What kind of bulb are you using exactly Mark?
*Nine times out of ten it's the bulb by itself that's responsible for the better light, so if a tied-in lamp supplied by the same people costs £££ you're basically paying for their marketing and larger profit margin.

P.S. In terms of magnification, head-mounted magnification works better for more people than a magnifying lamp which often seem to get in the way. I recommend giving cheap reading glasses a shot (the type sold by Lidl or Aldi for example) before investing in a proper magnifier, see if you can get used to the magnification.
I have both types and actually prefer the reading glasses to the headband magnifier, since they're less hassle and more comfortable to wear.
