Why Sunmaster

Proper lighting is a key ingredient in promoting robust, healthy growth as well as meeting the needs of various plant growth phases through optimised spectral outputs. Sunmaster® provides the largest, most comprehensive supply of HID lamps and ballasts specifically tailored for the hydroponic and horticultural industries. Simply stated, Sunmaster lamps deliver intense light output with nutritional spectral values.

Sunmaster physicists and design engineers have worked in tandem with lighting professionals and agricultural researchers to produce lighting systems that feed various plant photosynthetic requirements. Our arc tube dosing technology achieves more usable light energy without sacrificing intensity or lamp life. We concentrate on providing high PAR values (Photosynthetically Active Radiation between 400 and 700nm), an accurate way to measure useable light for plant growth (established by Dr. McCree).

The Sunmaster Science

A Healthier, More Nutritious Light...

SUNMASTER has harnessed the unique versatility and flexibility of metal halide technology to create a revolutionary new line of artificial lighting products for plant growth. By carefully blending specific halides and metals in the arc tubes, we have created products which offer significantly more usable light energy than standard metal halide lamps. The result: SUNMASTER products provide richer, healthier, more nutritious light.

Par Watts for Plants... Lumens for People

At Sunmaster, we believe there is a better way to measure artificial light: Photosynthetically Active Radiation(PAR) watts. While lumens are based on the eye sensitivity curve of human beings, PAR watts objectively measure the total watts of light emitted by a lamp in the spectral region that plants respond to. They account for the nutritional value of light and are a direct measure of the light energy available for photosynthesis.

System Solutions

Sunmaster is the only company that develops and manufactures complete HID lighting lamp and ballast systems for plant growth. Our unique lamp/ballast corporate partnership provides a strong foundation for new product development and proven product offerings, unmatched in the lighting industry.


From ISO 9001/2000 certified divisions to state of the art manufacturing processes, Sunmaster consistently delivers robust products with quality in mind. Our tight process controls and weld-less lamp designs help to assure excellent field reliability.

Spectral Famlies

Sunmaster lamps are tailored to promote optimum development at each plant growth stage. No other source can rival Sunmaster's ability to deliver customized spectral outputs for the different plant growth phases.
