The LumenstarLED LS-UW-MR is a purpose-built waterproof housing engineered to house MR16 format lamps in fully submerged or continuously wet environments. Operating at 12V DC, it integrates seamlessly with low-voltage landscape and aquatic lighting systems commonly used in residential and commercial installations. Its underwater-rated construction ensures long-term performance even when fully immersed, making it an essential component for pool lighting, water feature illumination, and marine-adjacent applications.
The housing's watertight sealing system is designed to prevent water ingress under sustained submersion, protecting both the lamp and electrical connections from moisture damage. This level of protection is critical in applications where water pressure, chemical exposure (such as pool chlorine), and temperature fluctuations are constant concerns. The robust seal integrity of the LS-UW-MR gives installers and end users the confidence that their underwater lighting investment will last season after season without compromise.
Compatibility with the standard MR16 bulb format is one of the most practical advantages of this housing. The MR16 is one of the most widely available lamp types on the market, offering a broad range of wattages, colour temperatures, and beam angles. This means you can tailor the light output of your underwater or wet-location installation precisely to your design intent — whether that calls for a narrow spotlight beam or a broader wash of light across a water surface.
Powered by 12V DC, the LS-UW-MR is fully compatible with standard low-voltage transformers and LED drivers used in professional landscape lighting systems. This low-voltage operation also adds an important layer of electrical safety for submerged applications, reducing risk in environments where water and electricity must coexist. Installers across Canada rely on low-voltage aquatic systems precisely because of the added safety margin they provide in residential and public-access water features.
Available through Lumibox.ca and distributed by LumenstarLED, the LS-UW-MR is the right choice for electricians, landscape lighting designers, and pool contractors who demand professional-grade underwater spotlight housings. Its combination of MR16 compatibility, 12V DC operation, and underwater-rated sealing makes it a versatile, reliable solution for any project where light meets water in the Canadian climate.
