My wife, who is an avid quilter, just bought a new very small ( 0.5 inch diameter by 1.5 inch length) light on a very thin flexible metal shaft. I immediately though it looked very much like the small Mckenzie flex shaft vise light I use constantly. This is the one that fits on the 3/8 inch shaft on my Barracuda vise.

Its much cheaper, about $30 compared to the McKenzie light. It is made to stick to the side of a sewing machine, but with some effort it could be easily adapted to your fly tying desk.

I have no financial interest in this company but here is the information:

Anyone have any experience with this light?
