INFO
Compact Explosion-Proof LED for Class I Division 1 Tight Spaces
Confined hazardous areas rated for the most stringent Division 1 classification need a fixture that's both compact and factory-sealed — the Block Mini Series H1 was designed for exactly that.
Block Mini Series H1 (BLM2 H1) is a compact, explosion-proof LED luminaire engineered for hazardous location applications requiring high reliability, long service life, and simplified installation. It's certified for Class I Division 1 and Division 2 environments, as well as Zone 1 and Zone 2 locations, where flammable gases, vapors, or combustible dusts may be present.
Designed with a factory-sealed housing and advanced thermal management system, the BLM2 H1 operates safely in high ambient temperatures up to 65°C (149°F) while maintaining consistent light output and extended lifetime. Its compact and lightweight construction makes it well suited for low mounting heights and space-limited installations.
Key Features
