When the Heat Rises, Reliability Matters Most
In industries like steel production, chemical processing, and power generation, heat is more than an environmental factor — it’s a constant adversary. Traditional HID and MH fixtures burn out quickly, forcing costly replacements and unplanned downtime. Every failure not only drives up expenses but also puts workers at risk. In these environments, lighting must be about trust, safety, and operational continuity.
Introducing the Modular Hot Series
That’s why Red Sky Lighting created the Modular Hot Series (MDH) — a highbay designed to deliver robust, dependable performance where others fail. With lumen packages from 30,500 to 114,500, the MDH replaces 400–2000W HID/MH fixtures while cutting energy and maintenance costs by up to 70%. Seven precision beam options ensure light goes precisely where it’s needed, whether that’s on conveyor lines, casting floors, or wide-open bays. And with IP67 waterproofing, 3G vibration resistance, and impact ratings up to IK10, the MDH doesn’t just handle the heat — it dominates it.
Safety & Reliability at the Core
Worker safety and system reliability are the foundation of every Red Sky product, and the MDH is no exception. Emergency backup options ensure visibility when power is lost, providing up to 3,000 lumens for 90 minutes or 1,500 lumens for 180 minutes. FCC certification, robust ingress protection, and vibration-tested construction mean customers can trust their lighting to perform when it matters most. The MDH isn’t just lighting a workspace — it’s safeguarding people and operations.
Built for Durability
Harsh environments demand tough materials. That’s why the MDH features marine-grade aluminum housing, 316 stainless steel hardware, and 720-hour salt spray resistance for superior corrosion protection. Rated for more than 122,000 hours at 158°F (70°C), this fixture keeps working long after others fail. Durability here isn’t just about ruggedness — it’s about delivering predictable, long-term value with fewer disruptions.
Easy to Install, Easy to Maintain
Time is money, especially in heavy industry. The MDH simplifies installation with quick terminal blocks, tool-free wiring, and adjustable lamp angles that don’t require screw disassembly. Its direct retrofit design makes replacing old HID/MH systems straightforward, minimizing downtime during upgrades. Contractors and facility managers save valuable hours on every install — and those savings add up.
Designed with Sustainability in Mind
The MDH is not only efficient but also powerful. With a lumen efficacy of up to 170 lm/W, the Modular Hot Series reduces energy consumption without sacrificing light quality. A longer service life means fewer replacements, less waste, and a lower overall environmental impact. Optional CRI 80 versions offer improved visibility and worker comfort, delivering up to 150 lm/W. Even packaging and materials are designed with recyclability in mind, aligning with modern sustainability goals.
Backed by Red Sky, Trusted by Industry
Available in two finishes, black and gray, the Modular Hot Series blends performance with a modern look. And like every Red Sky product, it’s backed by a 5-year warranty and the confidence of a team dedicated to safety, durability, and innovation. The MDH is more than a highbay fixture — it’s a complete solution for safer, more reliable, and more sustainable lighting in the harshest environments.
