Advice on a goood D50 or similar desk to lamp or bulb (Im in the UK)

[IWC Doppel]

Any advice here I have looked through Solux and a few sites but can't seem to see if a normal BC D50 light bulb might be available or a small desk top lamp to help with reviewing colour prints. I do mostly B&W and don't want a large light box, but something better easier than walking to the window and for use at night when printing.

My screen is a 27" iMAC cailbrated at 100cd/M2

There was an instructive discussion on this general subject last September which you may find helpful: http://www.luminous-landscape.com/forum/index.php?topic=70438.0
