So why not just switch these on when you enter the loft and turn them off when you leave?
Thanks, I will have to try that first and see how long the batteries last. The main problem is when I am behind the TV aerial or the cold water storage tank, particularly if I am working on the bungalow, so I could place the light to cover those. I suspect that I could find my way out fairly easily if I was anywhere else in the loft if I crawled on all fours.
