## Frequently Asked Questions

Model: SGL-2808

What pole diameter is required for mounting the SGL-2808 luminaire head?

The SGL-2808 luminaire head features a standardized inner tenon diameter of Ø76 mm (3 inches) with an internal sleeve clearance of Ø78 mm. It slips directly over standard Ø76 mm round garden light posts or spigot adapters, secured with 3 high-tensile stainless steel locking set-screws. Does the standard package include the light pole?

No, standard supply includes only the self-contained luminaire head assembly with integrated monocrystalline solar panel, deep-cycle LiFePO4 battery, and LED optical modules. Light poles are excluded from the supply scope to avoid excessive international freight costs and volumetric container surcharges. How many continuous rainy days can the SGL-2808 sustain?

Powered by a high-capacity deep-cycle 3.2V 60Ah (192Wh) LiFePO4 battery pack coupled with an intelligent PWM multi-stage dimming controller, the SGL-2808 sustains over 3 to 5 continuous rainy or heavily overcast days from a single full charge. What is the recommended mounting height and post spacing?

The recommended mounting height is 4 to 6 meters above finished grade. With its precision 140° × 70° crescent batwing optical lens array, optimal pole spacing ranges between 14 and 21 meters, delivering uniform illumination with zero glare. Can the SGL-2808 be configured for AC mains power?

Yes. In addition to the stand-alone solar configuration, we offer the SGL-2808-50W-AC mains hybrid version (AC 100-240V 50/60Hz) utilizing the identical aesthetic luminaire housing, ideal for shaded sites or hybrid municipal infrastructure projects.
