Grolux Sylvania 600w - 400v Professional HPS Lamp

The Sylvania Grolux 600W/400V HPS lamp comes with patented arc tube technology that delivers the highest rate of photosynthesis efficiency of any lamp in the world.

The performance is maintained at an exceptional standard due to the improved build and structure of the outer structure of the lamp, as well as being perfectly optimised for the highest Phytolumens or PAR output – the GroLux light spectrum maximises the red output essential for plant growth and flowering. The GroLux is also an industry leader in lumen maintenance with a whopping 95% at the end of lamp life

To be used with 400v ballasts only, do not use this bulb on a normal 240v ballast.

  • High PAR output
  • High Red spectrum output for increased yields
  • 400v technology
