The Dewalt DCL079 tripod LED light is absolutely brilliant for places where there is no mains electric. The light output is awesome and is brighter than a mains powered halogen lamp. I have been using this LED work light for months, in a property where there was not mains electricity installed. This meant that I could continue working when there were poor lighting conditions. In the UK, this is marked at 18V XR compatible, but in other countries it might be marketed as the 20V Max.
