Sylvania Grolux 600w 400v Lamp



400v lamps are taking both hobby enthusiasts and commercial scale growers by storm. For decades the majority of growers have been running 230v systems. While these 230v systems work effectively enough, by upscaling to higher frequency 400v systems, you're getting more bang for your buck. You'll use the same power and get a better performance. Why pay more for less?

This 600W / 400V HPS lamp features special patented arc tube technology that delivers rapid growth rates by increasing photosynthetic efficiency. It's optimised for an extremely high PAR output, maximising the levels of red light that are essential when deep into flower. Sylvania is also an industry leader in lumen maintenance; this Grolux lamp will still offer a whopping 95% efficiency at the end of its lifespan (of around 12 months). Put simply, these lamps stay brighter for longer!
