LED lights are much safer than lighting systems based on incandescent bulbs, but it is important to take a number of extra precautions when decorating your Christmas tree with them: Turn off the lighting: don't leave your tree lights on when you leave the house or go to bed. This will reduce the risk of an accidental short circuit and support responsible energy consumption. Use quality power strips: always use EU-approved cables and power strips, and avoid overloading them. The excess of decorative elements plugged to the current is especially common at Christmas time. Keep heat sources away: make sure you buy a fireproof Christmas tree and avoid placing it near fireplaces, radiators or any other heat source that could cause unnecessary accidents.
