To use this Cole 5 - Spot Black Spot Light, first ensure you have an E14 bulb. Install the bulb in the fixture. You can then adjust the lamp head up to 90 degrees tilt and 350 degrees turn to direct the light as desired. This light is for indoor use only, specifically in hallways. When choosing a bulb, if you want dimmable functionality, select a dimmable E14 bulb. Since the cable is not replaceable, handle it with care. Keep the light clean by gently wiping the metal and glass parts with a soft, dry cloth. Do not exceed the maximum bulb wattage of 40W to avoid overheating.
