SL-WL-B4S IP65 Waterproof Square LED Wall Lamp | 18W Bulkhead Ceiling Mounted Outdoor Light with 120° Beam
The SL-WL-B4S IP65 Waterproof Square LED Wall Lamp is a flush bulkhead luminaire engineered for porches, balconies, corridors, building facades and garden walls. Built with a die-cast aluminum body and a frosted glass diffuser, this 18W square ceiling mounted LED wall lamp delivers a wide 120-degree beam that washes surfaces with soft, uniform light and no glare. The black matte frame with visible stainless screws and the slightly raised pyramid-shaped diffuser give the fixture a clean, architectural look that suits modern and minimalist buildings. Certified IP65 against dust and water jets, the SL-WL-B4S is water-jet tested in the factory, making it the dependable 18W outdoor bulkhead light for rain, snow, coastal and humid environments. Available in 3000K, 4000K, 5000K and 6000K with black, white, grey or custom RAL finishes, it delivers 50,000 hours of life with a 3-year warranty.
Key Difference: This square bulkhead light combines a flush ceiling or wall mount with a wide 120-degree beam and an IP65 water-jet-proof seal. The aluminum body with glass diffuser dissipates heat efficiently while the frosted pyramid lens spreads light evenly - a practical, long-lasting IP65 waterproof square bulkhead light for balcony and porch applications, backed by factory testing.
