INFO
NEMA 4X Rugged LED Lighting for Corrosive, Coastal Environments
Salt spray, humidity, and constant vibration destroy ordinary fixtures — the Block Harsh Series is purpose-built to shrug off marine and petrochemical conditions for years.
Engineered for harsh environments, the Block Harsh Series delivers outstanding efficiency with a luminous efficacy of up to 150 lumens per watt. Built to withstand high humidity, dust, salt spray, vibration, and temperature fluctuations, it's ideal for coastal facilities, petrochemical plants, marine platforms, and rugged outdoor settings.
With 10kV built-in surge protection and a dimmable driver, the Block Harsh Series supports productivity in challenging conditions while lowering energy costs. A self-contained LED and driver compartment with external cooling fins ensures effective heat dissipation from -40°F to 140°F, and the copper-free aluminum housing resists corrosion in chemical or marine environments — all backed by a 10-year warranty.
Key Features
- Rugged Construction: Built to withstand extreme temperatures, vibration, water, and dust. Copper-free aluminum body and frame for corrosion resistance.
- Excellent Heat Dissipation: Integrated LED and driver compartments with external fins provide efficient heat dissipation for reliable operation from -40°F to +140°F.
- 3 Optic Options: 25°/60°/120° available for different applications from spot to flood for optimal light distribution.
