Light Efficient Design RP-SDL-20W-40K-BK-G1 20W LED Solar Display Light

Solar LED Display Light for Signs and Walls by Light Efficient Design

The RP-SDL-20W-40K-BK-G1 from Light Efficient Design is a 20W solar-powered LED display light designed for lighting signs, billboards, advertisements, and walls. It is suitable for exterior display applications. Key features include 2000 lumens at 4000K and an IP65 rating.

Key Features and Benefits of This Solar Display Light

A 2000 lumen output at 4000K gives a cool white light that helps keep sign faces and walls readable at night. The 120 degree beam spreads light across wide surfaces. The IP65 rating (protected against dust and low-pressure water jets) suits exposed locations, and a 50,000 hour average life limits maintenance.

Where to Use the RP-SDL-20W-40K-BK-G1 Solar Display Light

This light is well suited for signage, billboards, advertisements, and walls where running power is difficult or costly. Its operating range is -4°F to 104°F (-20°C to 40°C), so check that against local winter conditions before specifying it for northern sites.

Installation and Compatibility Checks

The fixture is not dimmable. Mounting arm brackets, 7.5 inches long, are sold separately as RP-SDL-B1L-LB-G1, though the listing notes the light can be mounted without them. Battery and solar panel details are not shown on the Lumenco page, so review the specification sheet before ordering.

Additional Buying Context

The manufacturer warranty is 3 years, and the fixture lists FCC and RoHS compliance. Its CRI (Color Rendering Index) of 80+ suits general sign and wall lighting, so compare CRI across other options if accurate color rendering is critical.
