Dimlux Lighting - Loved by Commercial Growers!

The Dimlux 600w Full Fixture is one of the most effective lighting systems on the market; producing bigger yields and better quality produce than is possible with traditional HPS lighting. This is thanks to the use of 400v, ultra-high frequency technology, which greatly enhances the spectral output while reducing operating temperatures. This technology was until recently, only available to the professional horticultural industry, but has now been engineered to run from standard 230 volt mains supplies. Dimlux lighting really comes into its own when teamed up with the Dimlux Maxi Controller unit. You can then run up to 160 of these fixtures from a central point, regulating lighting output levels so that your plants always stay within the correct temperature and VPD (vapour pressure deficit) ranges, as well performing a host of other features and simultaneously regulating CO2 distribution, heaters and humidifiers. WOW!

How the Dimlux Expert Series 600 Watt Works

Used by the grow industry, professional 400 Volt HPS lamps have a number of key benefits which make them superior to standard HPS lamps – even ones being run from top-quality digital ballasts.

A 400 Volt HPS lamp is much more efficient than a standard lamp. Both systems consume 600 watts and therefore cost exactly the same to run but the Pro HPS lamps run at a higher voltage and a lower current. Dimlux 400 Volt Pro HPS lamps produce more light for the same power consumption and will deliver at least 10% higher yields compared to even the best standard systems. In fact, when they are seen side-by-side, the HPS Pro lamps are noticeably brighter, run cooler and the light they produce is slightly whiter. So in addition to them giving a higher yield, plants grown under a Dimlux 400 Volt Pro HPS are healthier, happier and are at less risk of heat damage too.

The way that the Dimlux system works is that UK mains power (230 Volts) is fed directly to the combined ballast and reflector via a standard mains power lead. The special ballast then converts the mains electricity to drive the special 400 Volt / 600 Watt Philips Greenpower lamp. The distance from the ballast to the lamp is very short, meaning that virtually no power is lost through the connecting cable and removing the possibility of electromagnetic interference.

400 Volt / 600 Watt HPS Philips Greenpower lamps maintain their efficiency and light output for much longer than standard lamps. In fact they will normally last at least a year before they need to be changed out. It should be noted that normal HPS lamps and 400 Volt Pro HPS lamps are NOT interchangeable with different ballasts. Standard HPS lamps should only be used with standard or digital 230 Volt ballasts. 400 Volt Pro HPS lamps should only be used in lighting systems with a 400 Volt Pro HPS ballast. They can be identified by the HPS EL marking on them.

To get the most from these units, we recommend using them in conjunction with the Dimlux Maxi Controller. You can then do away with your contactor /timer setup and control up to 160 fixtures from a single point, scheduling on and off times and regulating output levels according to room temperature or VPD (vapour pressure deficit). You can also take advantage of numerous features like 'sunrise / sunset' mode, which eases plants between day and night cycles, mimicking the sun.
