Its rechargable, with 2 strip lights, and can be screwed to roof of van for some light at night. Can be removed and used as a work light as well. Its also go a built in stand so it can sit upright on a table etc.
Its bloody cracking and highly recommended

You get 3 hrs with one strip on, 1.5hrs with both on. Just plug it in to charge again. I will just be using it to pop in van to get stuff and need some light, so it should last a good while before needing charged
