400-Watt High Pressure Sodium HID Light Bulb - E26 Medium Base - Clear - 2000K Warm Yellow Light - 50000 Lumens - 24,000 Hours

400-Watt High Pressure Sodium HID Light Bulb: Industrial-Grade Illumination with Proven Performance

High-output illumination meets rugged reliability in the 400-Watt High Pressure Sodium (HPS) HID Light Bulb, engineered for demanding commercial and municipal applications. Designed with a standard E26 medium screw base and a clear ED18 envelope, this high-intensity discharge lamp delivers 50,000 lumens of bright, amber-toned light at 2000 Kelvin — ideal for wide-area outdoor lighting, street illumination, and industrial security.

With a 24,000-hour rated life, this HPS lamp minimizes maintenance while delivering consistent performance where it matters most.

Why 2000K Warm Yellow?

The 2000K amber glow provides excellent visibility with high contrast, ideal for foggy or dusty environments. Its warm yellow tone reduces glare and enhances object recognition — a preferred choice for municipalities, transport hubs, and outdoor perimeters.

✔ Built for Large-Scale Lighting Applications

• Highway & Street Lighting – Proven choice for DOT and municipal lighting programs.

• Security & Perimeter Lighting – Bright, widespread coverage for safety-critical areas.

• Industrial Yards & Warehouses – Reliable performance in rugged outdoor spaces.

• Sports Facilities & Parking Lots – High-lumen output for broad, clear visibility.

• Ports, Airports & Logistics Centers – Trusted in critical infrastructure worldwide.

Legacy HID Power – But the Future Is LED

High Pressure Sodium lamps have long dominated industrial and outdoor lighting — but today’s LED retrofit technology offers superior energy savings, light quality, and longevity.

Why Upgrade to LED?

✔ Energy Savings Up to 70% – LED equivalents use less than half the wattage for the same lumen output.
✔ 50,000+ Hour Lifespan – Replace bulbs less frequently and reduce maintenance costs.
✔ Instant-On Performance – No warm-up time; ideal for motion sensors and timers.
✔ Improved CRI – Better color rendering for enhanced visibility and security.
✔ No Ballasts Needed – Bypass ballasts for simplified fixture design and fewer failures.
✔ Environmentally Safer – LEDs are mercury-free and fully RoHS compliant.

LED Retrofit Options for E26 Base HPS Fixtures

Upgrading is easier than ever with retrofit lamps built to match or exceed HID performance:

🔹 LED Corn Bulbs (Ballast Bypass) – Connect directly to line voltage (120–277V) for high-output lighting.
🔹 Type B or Universal Voltage LEDs – Eliminate ballast maintenance and future replacements.
🔹 DLC Premium Listed Options – Qualify for utility rebates and energy efficiency incentives.

Proper Disposal of High Pressure Sodium Bulbs

Like all HID lamps, HPS bulbs contain small amounts of mercury and must be recycled responsibly.

✅ Prepaid Recycling Kits – Easy and compliant lamp disposal.
✅ Certified Recycling Programs – Keep your facility green and regulation-compliant.
✅ Documentation Provided – Receive a certificate of recycling for your records.

Light More. Waste Less. Upgrade Smarter.

The 400W HPS lamp is a workhorse—but LED is the future of lighting. Cut costs, boost efficiency, and reduce maintenance with a clean, modern lighting solution.
