GoodBulb 400W Metal Halide HID Light Bulb: High-Output Cool White Lighting for Demanding Applications
Illuminate large spaces with powerful, clean white light using the 400 Watt Metal Halide HID Light Bulb. Featuring a clear ED37 envelope and robust E39 mogul base, this lamp emits a brilliant 33,000 lumens at 4000K Cool White, making it ideal for high bay industrial, warehouse, gymnasium, parking lot, and outdoor area lighting. With a 15,000-hour rated lifespan, this high-intensity discharge (HID) lamp delivers consistent brightness and color rendering in tough, high-demand environments.

Why 4000K Cool White?

The 4000 Kelvin color temperature delivers a neutral white tone that enhances visibility, contrast, and clarity. It’s perfect for commercial or industrial settings that require high performance without the yellow hue of high pressure sodium or the blue tint of daylight lamps.

• Warehouses & Distribution Centers – Bright, high-lumen output improves safety and productivity in large interior spaces.

• Parking Lots & Security Lighting – Clear illumination enhances security and camera visibility.

• Gymnasiums & Arenas – Crisp 4000K light ensures visual clarity for sports and events.

• Street & Area Lighting – Designed for pole-mounted fixtures in roadway or municipal applications.

Built for Rugged Performance

• Ultra-High Lumen Output – 33,000 lumens for intense, widespread illumination.

• 15,000-Hour Rated Life – Supports demanding use cycles with reduced maintenance.

• Clear ED37 Bulb Design – Offers maximum light transmission and optical clarity.

• E39 Mogul Base – Standardized base for compatibility with most high-wattage MH ballasts.

Metal Halide Performance – But LED Is the Future

Metal halide lamps have served industries for decades with powerful light—but LED technology now outshines it in every way.

Why Upgrade to LED?

• Up to 70% Energy Savings – Cut energy costs by switching to high-efficiency LED replacements.

• 5–10X Longer Lifespan – LEDs last significantly longer, reducing downtime and labor costs.

• Instant-On Operation – No warm-up time, flicker, or restrike delay like traditional HID.

• No Mercury – Safer for the environment and easier to dispose of.

• Ballast-Free Options – Modern LED retrofits eliminate reliance on aging HID ballasts.

LED Retrofit Options – Ready to Replace

Upgrading your E39 mogul base MH fixtures is easy with LED retrofit lamps designed to drop right in:

🔹 Ballast Bypass LED (Type B) – Connects directly to line voltage, bypassing outdated ballasts.
🔹 Plug & Play LED (Type A) – Compatible with select magnetic or electronic HID ballasts for quick installation.
🔹 Hybrid LED (Type A+B) – Use with or without a ballast for maximum upgrade flexibility.
