All-in-one, off-grid construction
The 15W Solar Wall Pack LIFEPO4 packs the solar panel, the LED light engine and the battery into a single black wall-mounted body. There is no separate panel to mount on a roof, no remote battery box, no power source to find — which means no trenching, no conduit and no wiring. For a contractor, that turns a half-day electrical job into a bracket, a level and a few screws. The panel angle is adjustable, so once the fixture is on the wall you can still fine-tune the tilt toward the strongest sun exposure of the day, an important detail at Canadian latitudes where the sun sits low for much of the year.
Light output and light quality
This fixture produces 1500 lumens and compares to a 100W HID wall pack, while its 4000K neutral white colour temperature keeps colours honest — useful when you need to read a licence plate, a door number or a parts label at night. The 100° beam angle spreads light across a wide wall wash rather than a narrow hot spot, covering entrances, walkways and equipment areas evenly. Rated life is 35,000 hours (L70), so the LED output stays dependable season after season.
Battery, charging and operating modes
The advanced LiFePO4 (lithium iron phosphate) battery is rated for at least 2000 charge cycles, charges in 7 hours and delivers 50 hours of battery life on a charge — a real buffer through cloudy stretches. Fast charging happens between 32°F and 149°F, and the fixture operates from 5°F to 113°F. Three operating modes are selectable: dusk to dawn for continuous night presence, timer for a set run after sundown, and motion sensing for security duty where light only appears when someone approaches — the mode that stretches runtime the furthest in short winter days.

Mounting, applications and documentation
The standard model installs with the included anti-theft screws, a welcome touch on remote sites. The magnetic version (part number SL-SWL-15W-40K-BK-G2-M, UPC 197810000266) includes four ceramic round base pot magnets, each holding up to 35 lbs for a total pull strength of 140 lbs — made for shipping containers, steel siding, silos, trailers and temporary job-site setups where nothing should be drilled. Typical applications include warehouse and workshop side walls, farm buildings, municipal storage yards, marina and dock buildings, cottage sheds, parking areas, laneways and back entrances of small businesses.
