The Solar Motion Floodlight does not use electricity. It uses solar power to recharge its batteries, and is 50-LED, which I assume is pretty bright. The website says it is as bright as a 10w halogen bulb. Since it is based on motion detection, it will stay on your choice of 15-60 seconds. Since there are no wires, you can mount it almost anywhere without having to worry about all those wires hanging around. And the solar panel can be position up to 15 feet away from the light. It also has an automatic-off switch, and an adjustable light sensor that prevents daylight turn-on. Cost is about $50.
