As the title says I am looking for one that will last more than a couple of hours. I have one that I bought from Screwfix a couple of years ago but it's battery life is only a couple of hours. It's the yellow one that sits on two little horizontal feet about 6 inches long. Always use it for doing board changes in dark areas under the stairs etc... or when the power is off and I am up in a loft. It nearly always gives me a heart attack when I am working on a CU and I am suddenly plunged into darkness, initially thinking it's something I have done on the CU and forgetting I am relying on the worklight!
