The Red Sky Lighting Block Mini H1 is a compact, explosion-proof LED luminaire purpose-built for the most hazardous and demanding industrial environments. Engineered to meet the rigorous Class I, Division 1 standard, the Block Mini H1 is fully certified for use in areas where flammable gases, vapors, or liquids are present under normal operating conditions. Its robust and sealed design eliminates the need for external sealing fittings, significantly reducing installation complexity and long-term maintenance efforts.
This luminaire is an ideal solution for a broad range of industrial and marine applications, including oil and gas facilities, marine transport and logistics, water and wastewater treatment plants, and general area, floodlight, high bay, and low bay lighting. Despite its rugged capabilities, the Block Mini H1 is compact and lightweight—ranging from just 10.5 to 11.7 pounds depending on wattage—making it particularly suited for confined spaces and low mounting height installations. It offers exceptional versatility through various mounting options such as pendant and yoke configurations.
The Block Mini H1 is available in four power options—21W, 40W, 50W, and 60W—delivering high lumen outputs from 4,220 to 8,514 lumens with a remarkable luminous efficacy of 162 lumens per watt. It supports a universal input voltage of 120–277V AC for all models, while the 50W version also accommodates 347–480V AC systems. Operating on 50/60Hz frequency, it maintains a power factor of ≥0.90 and a total harmonic distortion (THD) of less than 20%. Dimming is supported via a 0–10V interface, allowing smooth control within a 10–100% range. Surge protection is rated at 2KV for 21W and 40W versions, and 6KV for the 50W and 60W variants.
Built for long-term durability and reliability, the Block Mini H1 is rated for extreme environments with ambient operating temperatures from -40°F to 149°F (for 21W/40W/50W models) and up to 147°F for the 60W version. It boasts an exceptional thermal management system that enables L70 lifespans exceeding 219,000 hours for the 21W, 40W, and 50W models, and 127,000 hours for the 60W model. T-code ratings vary by wattage, with the Block Mini H1 capable of achieving T6 and T5 classifications, ensuring safe operation in explosive atmospheres.
Optical customization is made easy with available beam distributions in Type 2, Type 3, and Type 5, and CCT options of 3000K, 4000K, or 5000K to match application needs. The color rendering index (CRI) exceeds Ra70, providing sufficient visual clarity in critical work zones. The luminaire uses a tempered glass lens for high impact resistance (IK08) or can be configured with polycarbonate for even greater durability (IK10). Stainless steel 316 hardware and a corrosion-resistant, copper-free die-cast aluminum housing ensure long-lasting performance in marine and industrial environments.
The Block Mini H1 meets a comprehensive list of safety and performance certifications, including UL844, UL1598, UL8750, UL1598A, and CSA standards C22.2 No. 137-18, No. 250.0, and No. 250.13. It is also compliant with FCC and DLC requirements. Environmental protection ratings include IP66 and IP67 for complete dust and water ingress protection, as well as 5G vibration resistance. Cable entry is via a ¾" NPT with 3-foot, 18/6 leads supporting line, neutral, ground, dimming, and 12V auxiliary wiring.
With its powerful performance, compact form factor, and full range of hazardous area certifications, the Red Sky Lighting Block Mini H1 delivers an advanced, reliable, and flexible lighting solution for explosion-prone environments. Backed by a 10-year warranty, it represents a long-lasting investment in safety, efficiency, and compliance across critical industrial applications.
