At Red Sky Lighting, we specialize in industrial LED lighting solutions that perform reliably in some of the world’s most demanding environments. From saltwater marine platforms and corrosive chemical plants to dusty manufacturing floors, high-vibration oil and gas sites, and extreme-temperature outdoor locations, we’ve seen what it takes to keep lights running where failure is not an option.
The Harsh Line is our latest innovation: a purpose-built lineup of marine-grade, corrosion-resistant LED fixtures designed specifically for harsh, but non-hazardous, industrial settings. These environments don’t require explosion-proof ratings, but they still demand high-performance lighting that can endure harsh conditions without compromise.
A Complete Lineup of Industrial LED Fixtures
Round Harsh Series: Compact, High-Output Round Fixture
The Round Harsh Series delivers up to 11,500 lumens in a compact 9-inch housing, engineered for high-output performance in tight, demanding industrial environments. With a high ambient rating up to 140°F (60°C), 127,000-hour lifetime, and resistance to dust, moisture, vibration, and salt spray, it’s ideal for marine, oil & gas, and manufacturing sites. Seven mounting options and three optics ensure a reliable fit and flexibility.
Linear Harsh Series: Long-Span Linear Fixture
The Linear Harsh Series delivers up to 150 lm/W and 147,000 hours of performance at 149°F. Built with rugged copper-free aluminum, it resists vibration, dust, and moisture. A dimmable driver, versatile mounting options, and quick wiring make installation easy. Ideal for coastal, utility, and processing sites. Backed by a 10-year warranty.
Block Mini Harsh Series: Low-Profile Surface-Mount Fixture
The Block Mini Harsh Series is a compact, low-profile LED fixture built for tough industrial environments with limited space. NEMA 4X-rated and factory-sealed, it resists corrosion, moisture, dust, and vibration—ideal for food processing, chemical plants, and coastal facilities. With a 219,000-hour lifespan at 149°F, multiple lens options, and a 10-year warranty, it delivers efficient, mission-critical lighting in harsh but space-constrained applications.
Block Harsh Series: Rugged Outdoor Fixture for Harsh Conditions
The Block Harsh Series delivers up to 150 lumens per watt with a 121,000-hour life at 140°F (60°C). Its NEMA 4X-rated copper-free aluminum housing resists corrosion, dust, salt spray, and vibration. Featuring 10kV surge protection, a dimmable driver, and multiple optics, it’s ideal for petrochemical, marine, and coastal industrial environments.
Round Max Harsh Series: The Heavy-Duty Flagship
At the top of the Harsh Line is the Round Max Harsh Series, designed for large-scale general area and high bay lighting. It offers lumen packages from 12,000 to 30,000, with five beam distribution options including 30°, 60°, and Types I, III, and V. This flexibility allows it to meet a wide variety of lighting challenges across open areas, outdoor zones, and high-ceiling interiors.
Constructed with copper-free aluminum housing and 316 stainless steel hardware, the Round Max Harsh Series is highly resistant to corrosion. It offers both tempered glass and polycarbonate lens options, allowing you to select the best balance of durability and optical performance.
The fixture is sealed to NEMA 4X and IP66 standards and passes 720-hour salt spray testing. It is designed to operate in temperatures ranging from -40°C to +65°C, making it suitable for both hot and cold climate conditions.
Installation is streamlined with Red Sky Lighting’s modular junction box system and multiple mounting options, including pendant, wall, ceiling, yoke, and stanchion. The system is pre-wired to reduce installation time, and the product is backed by a 10-year LED warranty with an L70 lifetime of over 110,000 hours.
