Sunmaster Metal Halide (MH) Retro Lamp - 600W | 240V | Runs on HPS/MH Ballast

Sunmaster 600W Metal Halide Conversion Lamp is a specialist HID grow lamp designed for growers who want the spectral characteristics of metal halide lighting while using compatible 600W HPS control gear. Also known as an HPS to MH conversion or retro lamp, it provides a convenient way to introduce metal halide lighting without requiring a separate dedicated MH ballast setup.

Designed for commercial greenhouse and hydroponic applications, the Sunmaster conversion lamp produces a balanced spectral output developed to support both vegetative growth and flowering. Its spectrum provides plants with usable light across important wavelengths for photosynthetic growth and development.

The lamp is rated at 600W with an output of 50,000 lumens and uses a T76 bulb shape. Sunmaster's arc tube dosing technology is designed to optimise usable light energy and provide a spectrum tailored to plant growth requirements.

A key advantage of this conversion lamp is its ability to operate on compatible 600W HPS control gear. This allows growers to change between compatible Sunmaster HPS and metal halide conversion lamps while retaining the same control gear, making seasonal or growth-stage lighting changes easier.

The Sunmaster 600W MH Conversion Lamp can also be used with compatible digital ballasts rated for the lamp. Always confirm ballast and lamp compatibility before installation and operate the lamp according to the ballast manufacturer's specifications.

With a rated lamp life of approximately 8,000 hours and a universal burning position, the Sunmaster 600W Conversion Lamp is a practical HID lighting option for hydroponic grow rooms, indoor gardens and greenhouse applications requiring a metal halide spectrum from compatible HPS control gear.
