Sunmaster CDX 600W Metal Halide Lamp 

Sunmaster CDX 600W Metal Halide Lamp

The Sunmaster Cool Deluxe Halide range is produced by Venture Lighting, the experts in metal halide technology.
Designed with a colour temperature of 7200K, this offers crisp white light with a strong blue bias and will help to grow compact plants with increased number of internodes to help them reach full potential.
Elevated levels of blue light promote larger leaves, thicker stems and increased chlorophyll levels for healthy, high yielding plants.
Featuring an E40 screw, these lamps can be used with most popular reflectors and can be powered by most 600W ballasts. 

Use
Metal halide lamps are ideal for use in the vegetative stage of plant growth and to the end of the 1st of flower.
Most digital or magnetic ballasts can be used with these lamps but make sure that they are only used on the 600W setting, do not use them at higher or lower power settings.

Tips
Due to the extra blue light produced by metal halide lamps they can help to promote resin production and improved colouration of flowers, growers often add metal halides back to the grow room for the last couple of weeks of flower.
