600W Metal Halide




We have sold many different 600W metal halide grow lights over the years and after much trialling and testing, we have settled for the best grow lamps on the market; the Sunmaster range from Venture Lighting.

More recently Maxibright have manged to produce a ‘budget 600W Metal Halide‘ lamp with the same colour temperature as the Sunmaster – 7200K.  For those just running their Metal Halides for a couple of weeks each cycle it is a fantastic option, for those running their Metal Halides on a more permanant basis we would still recommend the Sunmaster lamp.

Sunmaster lamps are exclusively tailored for the horticultural market and as such the lighting technology is geared solely towards growing plants. Therefore, the light provided by these metal halide Sunmaster lamps is of the correct blue spectrum needed to grow healthy plants.

Metal halide lamps are designed to mimic the amount of blue light that plants would usually get from the early summer sun, and they are intended for use during the vegetative stages of the plant growth cycle.

The light output by metal halides is measured in Kelvins, with a higher Kelvin rating corresponding with a greater amount of plant usable light. These 600W metal halide grow lights from Sunmaster are rated 7200K (Kelvins) and are at the higher end of the scale, putting out plenty of that all-important plant usable blue spectrum light for optimum growth and performance.

Many professional growers use a mixture of metal halides and high pressure sodium lamps in their grow rooms, often using one 7200K metal halide for every two sodium lamps to add extra blue spectrum light to their environment. A set-up like this will often obtain great results, with plants having access to an abundance of usable light to ensure strong, healthy, vigorous growth.

Wattage and Coverage

To give you an indication of the grow lights you’ll need we’ve included an estimate below of the amount of coverage each type of light will provide.

  • 250W – An area of around 0.6 to 0.7 metres squared
  • 400W – An area of around 0.8 to 0.9 metres squared
  • 600W – An area of around 1 to 1.2 metres squared
  • 1000W – An area of around 1.3 to 1.5 metres squared
