Megaman Low Energy dusk to dawn sensors automatically switch on at dusk and off at dawn and are ideal for security lighting. These give both ongoing reduced energy consumption and reduced replacement cost due to the significantly increased life. Some of these last up to 15 times longer than the incandescent filament or halogen lamp they replace. When both these benefits are taken into consideration, these lamps offer real ongoing value and ongoing savings versus the lamps they are replacing. Available in several types, wattages and caps these offer plenty of choice to suit your needs. If you cannot find what you are looking for, please call for further help.
