Using your CONTRISA pendant light is easy. First, find a suitable location in your modern or Scandi - style room to hang it. Make sure the mains voltage in your area is within 220 - 240V, 50/60Hz. Since it has no switch, you'll need to control the power at the source. When it's time to replace the illuminant, look for an E27 - type bulb that matches the exclusive design of this light. As for maintenance, use a soft, dry cloth to wipe the grey steel enclosure regularly to keep it looking great. Avoid using harsh chemicals or abrasive materials as they may damage the surface. Also, don't hang heavy objects on the light to prevent it from getting damaged.
