at the moment im using some battery powered led lights available from places like maplin.co.uk and cpc.co.uk. First i started with these 3 led lights made by Osram called dot-it. I bought 5 and there great for spot lighting and have magnetic or velcro pads you can stick to the back.

then a few months back i got the 'light bug' and bought a couple of 24 led lights made by Rolson from the same stores. These are massively brighter... Also just last week i went to the maplin store and bought the awesome 72 led light made by Rolson which is about 3 times brighter than the 24 led one and really does give a very workable light source.

Led's are better there much more brighter then the older lights
