Features Outstanding Durability - This underwater lighting combines ultra-thin panel technology with LEDs.The housing is made of corrosion-resistant high-quality polymer, filled with epoxy resin inside, which gives it a very high resistance to cracks, heat and chemical corrosion, 100% waterproof. Super Bright Lamp - 35W actual power, 3500 lm luminous flux, 140 ° beam angle provide wide illumination and high light coverage, overall dimensions Ã178mm x H25mm. Use up to 86% less energy than traditional halogen 300W lights and last 10X longer. Easy Replacement - Compatible with most PAR56 housing/niche except small SPA fixture, ideal for replacing 300W halogen lamps in common niches. With IPX8 protection, it's resistant to corrosion by chemicals used in swimming pool water treatment and is fully compatible with saltwater chlorination. Safe Working Voltage - 12V low voltage output that ensures safe underwater lights. During testing and installation, be sure to provide the 12V AC/DC Transformer required for proper operation. (Excluding Transformer and Pre-embedded niche) Reliable Quality & Professional Service - All lamps undergo rigorous high-temperature testing and IPX8 underwater testing checks before dispatch.
