Sunmaster – Cool Deluxe Metal Hallide Bulbs

SUNMASTER Cool Deluxe Grow Lamps emit light from 5000° to 6500° Kelvin, imitating the natural look of daylight. They are an ideal light source for the seedling and vegetative stages of plant growth, while still emitting a wide spectral distribution.

SUNMASTER Cool Deluxe Lamps surpass many other HID sources in PAR watts – the most objective measurement of total light energy available for photosynthesis. SUNMASTER Cool Deluxe Lamps set new standards in general plant lighting, promoting high levels of photosynthesis without compromise.

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. By providing your plants with this in the vegetative stage will ensure their growth rate will increase, the internodes stay tight so there is no stretching and there is plenty of new shoot growth to give a fuller, healthier plant that is ready and capable of providing and supporting larger yields when flowering.
