MH, MSH specifications

Hubbell MH and MSH series fixtures are integral components in modern lighting solutions, designed to offer efficiency, durability, and versatility for various applications. Ideal for outdoor, industrial, and commercial environments, these fixtures demonstrate Hubbell's commitment to innovation and quality.

The main feature of the Hubbell MH series is its use of Metal Halide technology, delivering bright, high-quality illumination that enhances safety and visibility in large spaces. This series can provide an impressive lumen output, making it suitable for warehouses, parking lots, and stadiums. The fixtures typically come with various wattage options, allowing users to select the output that best fits their specific needs.

On the other hand, the MSH series utilizes high-intensity discharge (HID) technology, known for its energy efficiency and long lamp life. These fixtures are designed to withstand harsh environmental conditions, making them ideal for outdoor applications such as street lighting and security lighting. The robust construction of MSH fixtures ensures that they can endure exposure to moisture, dust, and varying temperatures.

Among the key characteristics of both series is their compatibility with a range of control systems. Hubbell MH and MSH fixtures can be equipped with optional dimming and photo sensors, enabling smarter, more energy-efficient lighting management. This feature not only reduces energy consumption but also extends the lifespan of the lamps, resulting in lower maintenance costs.

Both series are designed with user-friendliness in mind, featuring tool-less entry for easy access to electrical components for maintenance or replacement. In addition, the fixtures offer adjustable mounting options, allowing for flexible installation in different environments.

The advanced reflector design in these fixtures ensures superior light distribution, minimizing dark spots and enhancing overall visibility. This focus on light quality is crucial for creating safe and productive environments in various settings.

Hubbell's ongoing commitment to sustainability is reflected in the design of the MH and MSH fixtures, as they prioritize energy efficiency and low environmental impact. By investing in these lighting solutions, users not only benefit from enhanced visibility and safety but also contribute to a greener future. In conclusion, the Hubbell MH and MSH series exemplify innovation in lighting technology, characterized by their efficiency, durability, and adaptability to diverse applications.
