Using your Nordlux Ethan 1-Spot Surface Downlight is easy. First, choose your preferred GU10 bulb and install it in the light. You can select either the black or gold reflector to get the look you want. The light is designed for indoor use, so keep it away from wet areas. When it comes to dimming, just use a dimmable GU10 bulb. Since the cable is not replaceable, be careful when handling it. To clean the light, use a soft, dry cloth to wipe the aluminium and metal surfaces. Don't mount it directly into insulation. If you have any questions or issues, contact the manufacturer for support.
