This fixture is so simple to use. Simply place it in the desired location and turn it on with the little built-in switch on the battery case. Made of high-quality metal fixtures with cool white LED bulbs (non-replaceable) that will burn for up to 4000 hours, putting out 95% less heat than traditional bulbs. The 3V watch batteries can be replaced and each will last up 80 hours. Plan them for a spot you can easily reach to flip the switch. If a fixture will not be lit for a long period of time, it is best to remove the battery. Metal is a burnished gold colour.
