In addition, this lamp also has the characteristics of easy installation, waterproof and sunscreen. The products are widely used in places such as roads, courtyards, showcases, shops, conference venues, stages, etc., especially as decorative lights for Christmas trees, which can create a warm and romantic holiday atmosphere.
