CK-400R Calitek brand electronic / digital ballast , for HID horticultural lamps , has a high power factor, high luminous efficiency as well as low THD ( Total Harmonic Distortion ), not to mention its energy saving more than satisfactory.

Equipped with ignition failure protection, suitable open circuit protection and end of lamp life protection technology, this Calitek 400W CK-400R ballast will not suffer from short circuits.

It is compatible with MH (Metal Halide) and HPS (High Pressure Sodium) bulbs, and its high operating frequency (60KHZ – 130KHZ) helps to give the lamp constant power, while extending its lifespan and l increase in its luminous efficiency.
