315W CMH Grow Light Fixture




315W CMH Grow Light Fixture


SunPlix 315W CMH grow lighting fixture utilizes Fuzzy Logic 4th Generation ballast technology. The patent technology keeps lumen maintenance rate higher than 95% at 30,000 hours and maintains the initial spectrum so you can use your light much longer than traditional HPS grow light.

Besides the long lamp lifetime, the fixture gives off full spectrum light which is similar to sunlight.

The light generates much less heat because more power is converted to useful light, not heat. Comparing to HPS grow light, it saves about half power.

  • CMH-315W digital ballast should work on operating voltage with corresponding bulbs. High power bulb can be used to dim to low power output, but not the reverse.
  • The work environment temperature for the ballast ranges from -40 F°/-40 C° to +122 F°/+50 C°, the maximum work temperature of its shell can be +158 F°/+70 C°.
  • The ballast should avoid working under high temperature environment which will affect its service life.
  • Combustible substances and corrosive gas should not be placed in the work environment of the ballast.
  • If a ballast is damaged, do not try to fix it. Users should exchange it with suppliers or send it to the factory for maintenance.
