I purchased a battery powered 10 LED twin head, motion sensor security light that appears to be good quality at a very reasonable price. It has since been installed and functions just as expected, throwing two circles of light below my front porch steps. The angles of light are adjustable to suit particular requirements and uses four AA Duracell batteries ( not rechargeables, these being slightly fatter so do not fit inside the battery housing). The unit was simple to fit and I am very pleased both with the purchase and the above average fast service provided by Lyco.
