## Frequently asked questions.

How does the fixture maintain illumination during overcast or rainy weather?

The SSL-1108 integrates high-capacity LiFePO4 battery storage with smart MPPT management, ensuring 3 to 5 consecutive nights of continuous dusk-to-dawn lighting during sustained inclement weather. What pole diameter is required for installation, and is the mounting arm adjustable?

The fixture requires a standard Ø60 mm (2.36") external pole tenon for secure slip-fit mounting with dual locking stainless steel bolts. The integrated mounting bracket allows adjustable tilt angles from 0° to +15° for optimal roadway beam targeting. Can the operating dimming profile and timer schedule be customized?

Yes. Default automated dusk-to-dawn multi-phase dimming (e.g. 100% first 4 hours, 50% next 4 hours, 30% dawn) can be tailored to project photometric specifications prior to factory dispatch.
