THT-EX presents the ideal combination for hazardous-area lighting:

L1733NS-L1733N Explosion-Proof Flood Light + S1912 Smart Sensor, engineered for petrochemical plants, storage tanks, hydrogen facilities, drilling platforms, and Zones 2, 21, 22.

●S1912 Sensor Highlights
Daylight Sensor: Detects approx. 2–2,000 lux for automatic dimming
Occupancy Sensor: Lights up with motion, dims when unoccupied
Approx. 80° detection angle
Saves 40–80% energy by reducing unnecessary lighting

●Lens
Lenses enable precise beam angles (narrow or medium beam)
Higher illuminance with concentrated light
Less glare and spill with controlled optics
Perfect for high-mount and long-distance applications

●Without Lens 
Soft and uniform light for wide-area illumination
Ultra-wide beam (110–140°)
Ideal for low to mid-height spaces and large-area flood lighting

●L1733NS Flood Light Features
High brightness, great heat dissipation, outdoor-ready
Certified for Zone 2, 21, 22/UL844 - Class I, Division 2 (Groups A, B, C and D) /UL1598
Enhanced energy efficiency when combined with the S1912 sensor

●Combined Benefits
Smart lighting = Safety + Efficiency + Energy Saving
Customizable optics: focused beam or wide flood coverage
Lower operating cost + extended product lifespan
Perfect for petrochemical plants, tank areas, hydrogen facilities, drilling platforms, pipelines, and loading zones
