Metal Halide Lamps MH-TO 400W
Product Overview
Our HQI-T 400W Tubular Metal Halide (MH) HID Lamps are high-performance traditional gas discharge lighting solutions, purpose-built for high-power industrial, commercial, and specialty applications. As a time-tested choice for large-space and precision illumination, these 400W MH bulbs deliver exceptional brightness, superior color rendering, and reliable long-term performance, making them the trusted solution for high bay warehouses, manufacturing facilities, stadiums, sports fields, aquariums, and horticultural grow spaces worldwide.
Key Product Features
✅ High Lumen Output & Luminous EfficacyWith a rated luminous flux of up to 40,000lm and luminous efficacy reaching 100lm/W, the HQI-T 400W MH lamp delivers powerful, uniform illumination for large, high-ceiling spaces, outperforming lower-wattage HID and traditional lighting solutions while maintaining energy efficiency.
✅ Superior Color Rendering PerformanceAvailable in 4000K (neutral white), 5500K (daylight white), and 6500K (cool white) color temperatures, with a high Color Rendering Index (CRI ≥ 80-95), these metal halide lamps provide accurate, natural color reproduction, ideal for industrial inspection, retail spaces, sports venues, reef aquariums, and horticultural applications where true color visibility and photosynthetically active radiation (PAR) are critical.
✅ Extended Service Life & ReliabilityBuilt with high-purity quartz arc tubes, robust electrode structures, and advanced getter technology, our HQI-T 400W MH lamps feature a rated lifespan of up to 15,000-20,000 hours, minimizing maintenance frequency and replacement costs for large-scale industrial and commercial lighting projects.
✅ Tubular (HQI-T) Design & Universal CompatibilityThe standard tubular (HQI-T) shape and E40 mogul screw base ensure seamless compatibility with most existing 400W HID high bay fixtures, floodlights, aquarium lighting systems, and industrial lighting setups, making them ideal for retrofitting legacy installations and new construction projects.
✅ Stable Lumen MaintenanceAdvanced arc tube design and gas filling technology ensure excellent lumen maintenance (up to 70-80% lumen retention over the full lifespan), providing consistent, flicker-free illumination throughout the bulb's service life, with no significant brightness drop.
✅ Durable Industrial-Grade ConstructionRugged borosilicate quartz glass envelope, reinforced internal support structures, and shock-resistant design ensure reliable performance in harsh industrial environments, withstanding vibration, temperature fluctuations, and heavy-duty operating conditions.
✅ Wide Application VersatilityDesigned for both indoor and outdoor high-power lighting, these MH lamps are suitable for a full range of commercial, industrial, and specialty scenarios, from indoor high bay warehouses to outdoor stadium floodlighting, reef aquariums, and horticultural grow facilities.
