High Pressure Sodium Lamps SON-T 400W
Product Overview
Our Tubular High Pressure Sodium (HPS) HID Bulbs are premium traditional gas discharge lamps engineered for professional outdoor lighting applications. As a classic choice for street and roadway lighting, these HPS bulbs deliver unmatched performance in foggy, rainy, and low-visibility conditions, making them the trusted solution for municipal roadways, highways, parking lots, industrial yards, and floodlight systems worldwide.
Key Product Features
✅ Exceptional Fog PenetrationThe unique golden-yellow light spectrum of high-pressure sodium lamps offers superior penetration through fog, rain, and haze, ensuring maximum visibility and safety on roads and outdoor areas even in harsh weather conditions.
✅ High Luminous Efficacy & Energy EfficiencyWith industry-leading luminous efficacy (up to 150lm/W for high-power models), these HPS bulbs deliver bright, consistent illumination while reducing energy consumption compared to traditional incandescent and halogen lamps, lowering long-term operational costs.
✅ Extended Service Life & ReliabilityBuilt with high-quality polycrystalline alumina arc tubes and robust internal structures, our HPS lamps feature a rated lifespan of up to 30,000+ hours, minimizing maintenance frequency and replacement costs for large-scale lighting projects.
✅ Tubular Design & Universal CompatibilityThe standard tubular (SON-T) shape and E40 mogul base ensure seamless compatibility with most existing HID street light fixtures, floodlights, and industrial lighting systems, making them ideal for retrofitting and new installations.
✅ Stable & Consistent IlluminationAdvanced arc tube technology and getter tablets ensure stable luminous flux maintenance (up to 80% lumen retention over lifespan), providing uniform, flicker-free lighting throughout the bulb's service life.
✅ Durable ConstructionRugged glass envelope, reinforced electrode structures, and shock-resistant design ensure reliable performance in outdoor environments, withstanding vibration, temperature fluctuations, and harsh weather conditions.
