Sunmaster Metal Halide 400w lamp

The Sunmaster Cool (Metal) Halide Deluxe range of Vegetative growth lamps have an altered colour temperature to maximise the amount of blue spectrum available. Sunmaster Cool Deluxe bulbs can provide up to 70% more blue light than standard Metal Halide lamps.

Most Metal Halide bulbs have a colour temperature of around 4000K, the Sunmaster is the only Metal Halide lamp in the UK which has a colour temperature of 7200K which is far more in the blue/white spectrum. Providing your plants with this optimum blue/white spectrum in the vegetative stage will ensure that their growth rate will increase, reduce internode spacing (less stretching) and generally a healthier plant that is ready and capable of providing and supporting larger yields when flowering.

* Please note: We recommend Sunmaster Metal Halide lamps for high-frequency Digital/Electronic lighting systems.

* We recommend replacing your lamps every 6-9 months for optimum growing results.
