Frequently Asked Questions

Q: What is the difference between the 90-minute and 180-minute emergency downlight options?

A: Both options function identically during normal operation as standard LED downlights. The difference is the internal battery capacity — the 180-minute version has a larger battery that provides double the backup illumination time during a power outage compared to the 90-minute version. Choose 180 minutes for larger spaces or stricter safety requirements.

Q: Do I need to purchase batteries separately?

A: No separate batteries are required. The emergency backup battery is built into the unit. However, it is not included as a loose accessory — it is integrated into the downlight itself. No external battery purchase is needed.

Q: What ceiling hole size do I need to cut for my chosen wattage?

A: Cutting size depends on wattage: 3W & 5W require a 75mm hole; 9W & 12W require a 120mm hole; 15W & 18W require a 145mm hole. Always confirm your wattage selection before cutting to ensure a proper flush fit.

Q: Is this downlight suitable for commercial or public buildings?

A: Yes. The SHINEKNOT SK-332 is designed for use in a wide range of environments including schools, supermarkets, office corridors, garages, stairways, and other commercial or public spaces where reliable emergency lighting is essential.

Q: Is this light dimmable during normal (non-emergency) operation?

A: Yes, the SK-332 is dimmable during standard AC-powered operation, giving you full flexibility to adjust brightness levels to suit the ambience of your space. In emergency mode, the light operates at a fixed output to maximise visibility.
