The LED barge light sets a new standard and incorporates a host of innovative features designed to make the unit extremely user-friendly. Made from tough, durable polycarbonate and using the latest high intensity LED and a uniquely designed lens, the BargeSafeSolar 2nm light has an incredibly low power consumption. The light can be installed in minutes, requires no operator intervention and has a permanent ON / OFF switch for easy storage. During daylight hours the solar module will charge the battery and the light will automatically begin operation at dusk - once the ambient light threshold drops sufficiently.
