| Twin-head emergency unit | Corridors, stairwells, small rooms, and open areas requiring directional emergency illumination. | Check emergency-mode light output, adjustable head direction, battery runtime, and photometric coverage for the space. | Wall or ceiling mounting is common. Aim the heads to illuminate the walking route and avoid glare. | General-purpose backup lighting where the beam needs to be aimed. |
| Exit sign with emergency illumination | Exit doors and locations where an illuminated exit indication is required. | Confirm the required sign legend, viewing direction, visibility distance, emergency operation, and applicable local listing or code requirements. | Choose wall, ceiling, or end mounting to suit the approach to the exit; check whether arrows or double-face viewing are needed. | Clearly marking an exit during normal operation and a power outage. |
| Recessed emergency downlight | Finished ceilings in offices, hotels, retail spaces, and public buildings. | Review emergency-mode output, beam distribution, ceiling compatibility, battery arrangement, and test or status indicators. | Requires a suitable ceiling cutout and access for wiring and maintenance; verify the product is designed for the ceiling condition. | Discreet emergency lighting that blends with recessed ceiling fixtures. |
| Emergency high-bay or industrial fixture | Warehouses, workshops, and other spaces with high ceilings. | Check emergency-mode photometric data at the mounting height, operating temperature range, battery runtime, and compatibility with the normal lighting system. | Confirm ceiling structure, suspension method, and access for inspection. A lighting layout may be needed to verify floor-level coverage. | Large or high-ceiling spaces where ordinary low-mounted units may not provide suitable coverage. |
| Weather-resistant emergency bulkhead | Covered exterior routes, service areas, garages, and damp or dusty locations when the unit is appropriately rated. | Verify the ingress-protection rating, permitted ambient temperatures, emergency output, battery runtime, and suitability for the specific exposure. | Use the specified seals, glands, and mounting method. An indoor-rated model is not automatically suitable for outdoor exposure. | Routes and utility areas where resistance to moisture or dust is an important selection factor. |
