Using your CONTRISA pendant light is easy. First, make sure your mains voltage is between 220 - 240V, 50/60Hz. Install the light in a suitable location for your modern or Scandinavian - style room. Since it doesn't have a switch, you'll need to control it from the main power source. When it comes to maintenance, simply wipe the black steel enclosure with a soft, dry cloth regularly to keep it looking great. Avoid using abrasive cleaners as they might damage the surface. Also, don't expose the light to excessive moisture or humidity. If the illuminant needs to be replaced, use an E27 - compatible bulb. And always turn off the power before making any changes to the light.
