Engineered with a compact, low-profile design, the SPZ-BL24 range is ideal for installations in confined spaces and areas where maintenance access is limited. Each fitting uses long-life, high-output LED technology combined with CoolXtrude™ thermal management to ensure consistent light output and a service life exceeding 10 years. Certified to IP66 and IP67, these luminaires are built to withstand extreme weather conditions, vibration, and corrosion in the harshest hazardous environments.
The product family includes the SPZ-BL24 standard bulkhead delivering up to 2,750 lumens, and the SPZ-BL24-W-EMX25 emergency bulkhead which features an intelligent self-testing emergency system with a tri-colour indicator and up to 3 hours backup duration. This makes it particularly suited for emergency escape routes and safety-critical areas.
Both variants provide versatile mounting options with multiple M20 cable entries and rear cable access, ensuring fast installation and secure protection of cabling. With UK design and manufacture, 5-year warranty and global certification. The SPARTAN BL24 bulkhead range delivers a dependable, high-efficiency lighting solution for new projects or retrofit of conventional bulkhead fittings.
