Description
Osram grow lamps have been around since HPS were first used to provide lighting for plants - they are exceptionally reliable lamps and produce consistent results, which is why they are one of our best-selling lamps to those still using HPS systems.
These Vialox Nav-T lamps have become the most popular in the range and are currently available in 400W, 600W and 1000W versions. As with all HID lamps they degrade over time and should be changed roughly every 8-10 months.
***Please retain original packaging for your lamps to validate the 12-month warranty***
