The range of Solistek Double Ended bulbs are all constructed from high end quartz glass for an enhanced spectrum and extra levels of UV light that no other competitor’s bulbs provide you with!
The Solistek 4k bulb is the first full spectrum metal halide designed for use during both vegetative and flowering phases of growth. The precise gas composition within the Solis Tek 4K bulb creates a balanced spectrum for great replication of the suns spectral output, perfect for those who want a piece of the sun in their grow room.
All Solistek double ended bulbs are designed for use with the Solistek A1 complete kit but can be used in conjunction with any other double ended lighting systems.
Exercise caution when working around Solistek HID lighting, always wear protective lenses that shield from UV light.
