A solar flood light should be selected by usable light output and operating time, not advertised wattage alone. For yards, billboards, parking areas and construction sites, compare lumen output, beam angle, mounting position and the size of the illuminated area.
The battery and solar panel must support the required nightly energy use. Ask whether the quoted system uses light control, timer control, remote control or motion sensing. Replaceable components can simplify maintenance for commercial installations.
When comparing a solar flood light manufacturer, request the exact lamp dimensions, battery capacity, panel wattage, IP rating, color temperature, warranty, carton quantity and CNY or export price basis.
