The 250W Tubular Metal Halide E40 lamp is a powerhouse of industrial illumination, specifically engineered to provide high-intensity light for expansive indoor environments. This lamp is a preferred choice for facilities that demand a clean, professional aesthetic, as it delivers a crisp 4100K cool white light. Designed with a sleek tubular profile, it fits seamlessly into high-bay fixtures and floodlights, ensuring that large floor areas in warehouses, factories, and sports halls are saturated with clear, uniform light that enhances safety and productivity.

Optimized for high-performance discharge systems, this metal halide lamp offers exceptional flexibility by operating on both Mercury and SON control gear. Depending on your existing setup, it can produce between 26,000 and 32,000 lumens, providing a level of brilliance that few other technologies can match. With a robust Giant Edison Screw (GES-E40) base and a reliable 10,000-hour operational life, this lamp is built to minimize maintenance cycles in hard-to-reach ceiling installations, making it a cost-effective and dependable lighting asset for any commercial enterprise.

Key Features

  • Massive Luminous Output: Capable of delivering up to 32,000 lumens, ensuring maximum visibility across large-scale industrial floor plans.

  • Dual Control Gear Compatibility: Versatile design allows for operation on either Mercury (26,000lm) or SON (32,000lm) ballasts.

  • Neutral Cool White Glow: The 4100K color temperature provides a natural, bright atmosphere that aids concentration and accuracy.

  • High-Intensity Discharge: Engineered for high-bay and low-bay applications where high mounting heights require a powerful light throw.

  • Industrial Durability: Features a 10,000-hour lifespan with a rugged GES-E40 base for a secure, vibration-resistant fit.

Why Choose This 250W Metal Halide Lamp?

Choosing the 250W Tubular Metal Halide lamp is the definitive solution for businesses looking to modernize their indoor facility lighting without replacing entire fixtures. Its primary advantage is the exceptional color rendering and "daylight" feel of the 4100K spectrum, which is far superior to the yellow-tinted alternatives often found in industrial zones. Furthermore, the ability to operate on different control gear types provides incredible versatility for facility managers overseeing diverse lighting estates. This lamp strikes the perfect balance between high-intensity performance and long-term reliability for demanding indoor environments.

Frequently Asked Questions

1. Can this lamp be used in outdoor floodlights? This specific model is recommended for indoor use only within enclosed fixtures. For outdoor applications, ensure the fixture is fully weatherproofed and rated for HID lamps.

2. Does this lamp require a ballast to operate? Yes, this is a high-intensity discharge (HID) lamp and must be used with a compatible 250W ballast and an external ignitor to function.

3. Why is there a difference in lumen output between control gears? The internal arc reacts differently to the electrical characteristics of Mercury versus SON control gear. Using SON gear provides a higher output of 32,000 lumens for maximum brightness.

4. How long does it take for the lamp to reach full brightness? Like all metal halide lamps, there is a warm-up period of approximately 3 to 5 minutes before the lamp reaches its full 4100K color temperature and maximum brightness.

5. Is it safe to handle the bulb with bare hands? It is best to handle the lamp with a clean cloth or gloves. Oils from your skin can create hot spots on the quartz glass, which may reduce the lifespan of the bulb.
