Sylvania Grolux HPS Bulb 400W, 600W Hydroponics Grow Light
Sylvania Grolux High Pressure Sodium Bulb
Sylvania have manufactured the Grolux to the same exacting standards for years and it remains THE reference dual spectrum lamp for the entire hydroponics lighting industry.
If you want to grow and flower under the same lamp then choose Sylvania Grolux HPS!
Sylvania Grolux High Pressure Sodium bulbs are 20% Blue and 80% Red
We do suggest you change your bulbs every 9 months, (three grows) as the illumination decreases.
Due to the sheer intensity of HPS lamps you’ll often find yourself coming away blurry eyed after tending to your plants….. We highly recommend protecting your eyes with these LUMII GROW ROOM LENSES
PLEASE NOTE THAT THESE BULBS NEED A BALLAST OR TRANSFORMER TO RUN THEM !!
