Buying Guide
- Emergency backup duration: Most units offer around 90 minutes of backup at reduced brightness. Consider longer runtimes if outages are common in your area.
- Color temperature and tunability: 3500K (warm), 4000K (neutral), and 5000K (cool) options help tailor spaces for tasks, safety, and mood. 5CCT options provide additional flexibility.
- Wattage and lumens: Higher lumen output at lower wattage saves energy. Look for fixtures delivering 5000+ lumens at 40W or less for bright, wide coverage.
- Durability and environment: For garages, workshops, or outdoors, select fixtures with durable housings and, if needed, IP ratings that match the environment.
- Installation ease: Ceiling or wall mounting compatibility, dimmable drivers, and optional linkable designs can streamline retrofits and future expansions.
