Underwater Road Stud Lights have powers of 8W, 100W, 300W, etc. To meet the brightness requirements of underwater lighting, Solar Studs light should be soft, non-glaring, waterproof, low voltage, stable performance, safe and reliable. The voltage of the underwater Solar Studs is a safe voltage, so you must use a transformer (purchase the transformer yourself). The special fuse connected by the reinforced double helix filament has high explosion-proof performance, safety and reliability.
