HIGH BAY HOT Series
Luminaire Type
Overview
The High Bay Hot Series is engineered to excel in high-temperature environments up to 176°F (80°C), rigorously tested and UL-verified to maintain 95.9% lumen output after 10,000 hours of continuous operation. It sustains at least 70% of original lumen level after 47,000-50,000 hours, translating to over 5 years of 24/7 life. A heavy-duty anodized aluminum housing resists corrosion, and vertical cooling fins enhance heat dissipation for die casting, metalworks, ironmaking, steel production, and chemical plants. Red Sky Lighting backs the complete system—LEDs, driver, housing, and gaskets—with a comprehensive 5-year warranty.

INFO
UL-Verified LED Lighting for 176°F High-Temperature Environments
Die casting, ironmaking, and steel production create ambient heat that destroys ordinary fixtures — the High Bay Hot Series is UL-verified to hold 95.9% of its output after 10,000 hours at 176°F.
The High Bay Hot Series is engineered to excel in high-temperature environments. Rigorously tested and UL-verified, it demonstrates lumen maintenance of up to 95.9% after 10,000 hours of continuous operation at an ambient temperature of 176°F (80°C), maintaining at least 70% of original lumen level after 47,000 to 50,000 hours — translating to over 5 years of life with 24/7 operation.
A heavy-duty anodized aluminum housing offers excellent corrosion resistance, and an innovative vertical cooling fin design and driver compartment enhance performance in extreme heat environments common to die casting, metalworks, ironmaking, steel production, power generation, and chemical plants.
