This quality 10W LED Floodlight is suitable for replacing any outdoor Halogen floodlight, yet uses only a fraction of the electricity.COB LED bulbs (or Chip On Board LEDs) have been especially designed & developed to increase the amount of lumens (i.e. light) per Watt. Not only do COB LEDs give off more light than normal LEDs, but they can give you energy savings of anything up to 90% when compared against Tungsten or Halogen equivalents. With the PIR sensor these are ideally suited to be used as a security light.
