Thanks for all the suggestions and I admit I didn't check out Amazon but was going on my understanding of the legal position here in Scotland. I've also realised that I probably do have GU10 halogen bulbs and hadn't thought about whether one of those would do. They're certainly warm, so long as the spectrum is OK.

Good luck!

The main purpose of an Adobe dual-illuminant profile is not to characterize tungsten lighting, which it does incidentally, but rather to get sufficient data points to characterize a wide range of blackbody radiation. Getting those two points means that you can use one profile for a huge range of lighting, everything from candlelight to dusk, which are all close enough to blackbody.

For non-blackbody sources single illuminant profiles are needed, and dual profiles probably should not be used.
