Well, I picked up a 40w daylight bulb for £2 in Wilkinsons this morning - It was the highest wattage I could get for the E14 / SES fitting.
By the time I sat down to work on my current project (a watercolour that requires masking off of lots of fine detail) it was already dark outside, so this was as good a test as any. Only managed half an hour's painting (too tired to do any more), but initial results are pretty encouraging.
Although the light definitely comes across as rather harsh compared to the 40w warm white LED that's usually fitted to my desk light, it's so much easier to a) see what I'm doing, and b) mix, apply and lift out paint.
Can't as yet comment on how this performs on longer sessions and when there is actual daylight outside, but seems like £2 well spent.
Thanks for all the advice folks, it's muchly appreciated.
