SKU: lit6004 Category:

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.

Tip: A HID (HPS/Metal Halide/CDM) bulb will drop approx. 30% of its lumen output within 12-14 months of continuous use. We recommend replacing every 3-6months for optimum plant growth and yield output!

PLEASE NOTE: To be used with 400v ballasts only. Do not use this bulb with a standard 240v ballast.
