A High-Performance 600w / 400v Grolux Lamp at an Unbeatable Price

If you're running a 600w / 400v system, you're going to need to replace your lamps at least once a year. Failing to do this will inevitably lead to a drop in growth rates and yields. Grolux lamps have been the industry standard for years, and there are plenty of good reasons for this: they're built to a high standard, they perform brilliantly and they come in at an excellent price. This new 400v lamp is a very attractive option for growers using Gavita Pro 600 and Dimlux 600w fixtures.

  • A great replacement for the lamps in 600w Dimlux and Gavita fixtures
  • High PAR output and red spectral output for increased yields
  • Super long-lasting - stays 95% efficient for up to twelve months!
  • Represents amazing value for money
  • Runs at 400 volts - more effective than standard 230 volt systems
  • Sylvania Grolux - specifically designed for optimum plant bloom

How the Sylvania Grolux 600w/400v lamp Works:

Why not take a look at our 400V 600W HPS Grow Lamp Shootout Blog Here 

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!

How to Use this Lamp:

Hold with a clean cloth and screw the lamp into the E40 bulb-holder fitting of your reflector until it will turn no further. It is important that the lamp is screwed very firmly into the holder. Failure to fit the lamp tightly will cause arcing inside the holder between the centre connector and the contact on the lamp. This will melt the solder contact on the lamp and irreparably damage it.

Please note: 400v lamps must ONLY be used in 400v ballasts never in standard 230v systems.

Warning: Once the lamp is switched on it runs extremely hot. As with all high pressure sodium and metal halide bulbs it is necessary to avoid touching the lamp with anything such as fingers or plants as this may cause severe burns or fires. In particular avoid sprays or liquids coming into contact with the lamp as this may cause premature failure or even an explosion. As with all lamps the light output they produce will decrease with use over time. One Stop Grow Shop recommends you replace your lamp regularly to maintain your garden efficiency.
