The Light Efficient Design SL-SDL-4FT-40K-BK-G2 is a 48-inch solar-powered LED display light fixture designed to illuminate signage, billboards, and exterior walls without the need for trenching or external wiring. With a 20-watt LED core delivering approximately 2,000 lumens at a 4000K cool white color temperature, this single fixture functions as a self-contained lighting solution that relies on integrated solar and battery components to operate. A user-friendly feature is the built-in LiFePO4 battery, rated for around 1,500 charge cycles, and a battery status indicator mounted on the side to help monitor remaining capacity. The fixture is specified with an IP65 ingress protection rating and a wet-location design, enabling reliable operation in outdoor environments and adverse weather conditions. The unit’s 120-degree beam angle distributes light broadly, and the product is rated for a long service life of up to 50,000 hours, aligning with low-maintenance expectations for remote or difficult-to-access installations.
During installation and operation, the fixture relies on daylight charging to provide roughly 8–9 hours of charging time, yielding about 4 hours of full 100% illumination with a gradual drain to 25% output later in the night. This performance profile supports signage and display applications where off-grid lighting is beneficial, particularly in areas where wiring is impractical or cost-prohibitive. The 47.2-inch length and 4.3-inch width/height give it a compact, low-profile footprint for mounting on walls or sign faces, and the product is compatible with standard mounting practices when paired with an appropriate arm bracket as referenced.
Overall, this solar LED fixture offers an energy-efficient, maintenance-conscious option for outdoor displays. It combines daylight-powered operation, replaceable LiFePO4 battery technology, and a durable enclosure suitable for wet locations, making it a practical choice for signage illumination where electrical wiring is limited or undesirable.
