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 10k metal halide is a unique product in that it is a bulb designed to be used during the last one to three weeks of flower to help increase essential oil production as well as helping with the ripening process. The Solistek 10K metal halide has greater amounts of blue light that can be used during vegetative growth stages to help suppress stem elongation on varieties that are known to have large internodes.   

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.
