## FAQ

Are mounting poles supplied with the SGL-003 Diamond garden light?

No. In accordance with standard international commercial supply terms, the SGL-003 is supplied strictly as an all-in-one luminaire head (pole excluded). It features an integrated Ø76mm spigot mounting tenon with dual locking set screws, allowing seamless slip-fit installation onto local 4m–6m steel or aluminum posts. How does the SGL-003 maintain lighting throughout prolonged rainy periods?

The luminaire is equipped with a high-capacity 3.2V 30,000mAh (96Wh) Grade-A LiFePO4 battery pack coupled with an intelligent PWM multi-stage dimming controller. On a full charge (6 hours in direct sunlight), it sustains over 3 to 5 continuous nights of dusk-to-dawn lighting. Is an AC grid electric version available for covered or shaded pathways?

Yes. Model SGL-003-50W-AC utilizes the exact same architectural diamond-fluted die-cast housing, but incorporates an internal 100–240V AC mains LED driver producing 5,300 lumens for heavily shaded courtyard environments. What is the recommended installation height and spacing for SGL-003?

For standard pedestrian promenades and park paths, an installation height of 4.0m to 6.0m with pole spacing of 14m to 21m provides uniform ground foot-candles with comfortable visual transition and zero cutoff glare. What international certifications and warranty support the SGL-003?

The SGL-003 is certified to CE, RoHS, and IP65 standards. It is backed by TPK's standard 2-year comprehensive factory replacement warranty covering the solar module, LiFePO4 battery, LED array, and optical diffuser.
