I think I will ask OH for one of these lights for Christmas too! Most of my spinning these days seems to be in the "quiet" time between seeing to the sheep and chooks at sundown and starting to think about dinner. We have wall lights rather than overhead ones and though they give a restful light, it's not great for working with.
I also find if I'm spinning my Heb or dark Shetland fleece, I need a light-coloured lapcloth or pinny and for my white and grey Shetlands I need a dark one - just so I can see the contrast.
