Super-Efficient, 1000 Watt 400V DE Grow Light

The Dimlux 1000w Full Fixture is one of the most effective lighting systems on the market today, 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 control 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 - 1000 Watt Works

Used by the professional horticultural industry, 400 Volt HPS lamps have a number of key benefits which makes 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 HPS lamp. Both systems consume 1000 watts and therefore cost exactly the same to run but the Pro HPS lamps run at a higher voltage and a lower current. 400 Volt Pro HPS lamps produce more light for the same power consumption and will give at least 10% higher yield compared to even the best standard HPS 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 400 Volt Pro HPS are healthier, happier and are at less risk of heat damage too.

The way that the 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 / 1000 Watt lamp. The distance from the ballast to the lamp is very short, meaning that virtually no power is lost through the connecting cable.

400 Volt / 1000 Watt Pro HPS lamps maintain their efficiency and light output for much longer than standard HPS 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. 400 Volt Pro HPS lamps 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) levels, so that plant temperatures always stay within range.

How to Use the Dimlux Expert Series - 1000 Watt Grow Light

Simply hang the combined ballast & reflector over the centre of the grow-space at an appropriate height using easy rolls or jack chain. Run the 4.0m kettle lead from the reflector to a standard UK mains outlet or your contactor and switch on.

Dimlux lighting is best used in conjunction with the Dimlux Maxi Controller. Two of these units can be connected to the Maxi Controller directly using speaker wire, and additional ballasts / fixtures can then be daisy chained from the original ballasts up to a total of 160 units. You can power multiple Dimlux fixtures using the following power supply units:

Green Power 4-Way Powerbox

Green Power 6-Way Powerbox

Green Power 8-Way Powerbox

Warning 1: When it is time to change out the lamp, make sure that it is replaced with another 400 Volt / 1000 Watt Pro HPS lamp such as the Horturion 400 Volt / 1000 Watt HPS EL. Using a standard HPS lamp in a 400 Volt lighting system will possibly cause damage, explosions or fire. Fit the lamp as shown in the image above so that the side with the small square is closest to the ballast and the other end is at the outer edge of the reflector.

Warning 2: When HID lamps are switched on they run 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.

Fitting your Double Ended Lamp

To fit your double ended lamp correctly see the image below

Please note:
Ensure that you follow manufacturer's guidelines when fitting your double ended lamp, as incorrect fitting will result in damage. This damage is NOT covered under the manufacturer's warranty.
