Using your Nordlux Cole 3 - Spot Black Spot Light is easy. First, choose a suitable E14 bulb (not included). Install the bulb into the base carefully. You can adjust the lamp head to the angle you need for the best lighting effect. To adjust, simply tilt it up to 90° or turn it up to 350°. When it comes to dimming, just select a dimmable bulb. As for maintenance, use a soft, dry cloth to clean the metal and glass parts regularly. Avoid using harsh chemicals as they may damage the finish. Don't try to replace the cable as it's not replaceable. Also, make sure to use bulbs with a maximum wattage of 40W to avoid overheating. Keep it away from water as it's for indoor use only with an IP20 rating.
