## FAQ

Are lighting poles included with the SGL-001 Hourglass garden light?

No. In accordance with standard international commercial supply terms, the SGL-001 is supplied strictly as an all-in-one luminaire head (pole excluded). It features an integrated Ø76mm mounting tenon socket with dual stainless-steel hex set screws, allowing seamless slip-fit installation onto local 4m–6m steel or aluminum posts. How does the SGL-001 perform during prolonged continuous rainy or overcast days?

The luminaire integrates an oversized 3.2V 20Ah (64Wh) Grade-A LiFePO4 battery pack coupled with an intelligent PWM multi-stage dimming controller. On a full charge (6 hours in bright sun), it delivers over 3 consecutive nights of dusk-to-dawn lighting without any utility grid connection. Is an AC mains electric hybrid version available for permanent shade installations?

Yes. We offer model SGL-001-50W-AC, which utilizes the exact same architectural hourglass die-cast housing and stepped PC optic, but incorporates an internal 100–240V AC mains LED driver producing 4,200 lumens for heavily shaded courtyard areas. What is the recommended installation height and pole spacing for SGL-001?

For standard pedestrian pathways and park walkways, an installation height of 4.0m to 6.0m with a pole-to-pole spacing of 14m to 21m provides uniform Class P ground illuminance with excellent photometric uniformity and zero visual cutoff glare. What certifications and factory warranty support the SGL-001?

The SGL-001 is fully certified to CE, RoHS, and IP65 standards. It is backed by TPK's standard 2-year comprehensive factory replacement warranty covering the solar panel, LiFePO4 battery, LED array, and optical assembly.
