The SL-SWL-15W-40K-BK-G2 is built around a 15-watt solar-powered LED engine that draws zero energy from the grid. Instead, it harvests sunlight through its integrated solar panel and stores that energy in a LiFePO4 (Lithium Iron Phosphate) battery pack — one of the most stable and long-lasting battery technologies available today. This makes the unit exceptionally well-suited for remote areas, construction sites, agricultural facilities, and any location where trenching for electrical conduit is cost-prohibitive or simply not feasible.
The 4000K color temperature of this solar wall pack produces a crisp, neutral white light that strikes the ideal balance between warm ambiance and functional task lighting. This CCT is widely preferred in commercial and industrial applications because it enhances contrast, improves facial recognition for security cameras, and reduces eye strain for workers and pedestrians alike. The black (BK) housing adds a professional, modern aesthetic that complements contemporary architectural styles.
One of the standout features of this unit is the LiFePO4 battery chemistry. Unlike standard lithium-ion cells, LiFePO4 batteries offer a significantly higher number of charge-discharge cycles — often exceeding 2,000 cycles — along with superior thermal stability and a reduced risk of thermal runaway. This translates directly into fewer battery replacements, lower total cost of ownership, and greater peace of mind in extreme temperatures, which is critical for Canadian outdoor lighting applications in provinces from British Columbia to Quebec and beyond.
As a Generation 2 product, the SL-SWL-15W-40K-BK-G2 incorporates refined engineering improvements over its predecessor, delivering enhanced efficiency in energy harvesting, smarter charge management, and more consistent lumen output throughout the night. The fixture is designed for straightforward wall-mount installation, making it accessible for electricians and contractors alike — with no need to connect to an existing electrical infrastructure. This dramatically reduces installation time and project costs.
Sourced from Light Efficient Design, a brand recognized for innovation in energy-efficient lighting, this solar wall pack is available through Lumibox (lumibox.ca) and LEDCo (ledco.ca) — two of Canada's leading LED lighting distributors. Whether your project demands sustainable site lighting, emergency backup illumination, or scalable off-grid solutions, this fixture delivers performance, durability, and long-term value.
