Helpful tips

  • Consider buying single-colour LED lights. LED strings in a single colour save even more energy than multi-colored LEDs – using up to 90% less than incandescent bulbs.
  • Never connect LED to incandescent light strings. This can pose a safety hazard and also reduce the life of the LEDs.
  • For optimum performance put your light strings on a timer, or purchase certified products with a built-in timer.
