Many thanks for the feedback.
I agree with others that it probably isn't perfect for short tools (or with a big chuck) - but the light is easily relocatable to the rear of the quill.
It works for me with shortish tools held in my R8 collet chuck.
It's definately an improvement on what I had and, for me, more light is better than less light.
For around £10, I am very happy with it.
Cheers
Andrew
