Used by the grow industry, Professional 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 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 Philips Master GreenPower Plus 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 Philips Master GreenPower Plus 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.

Crafted to perfection

Dimlux Expert Series 1000W DE EL UHF NanoTube. The Dimlux Expert Series 1000W DE EL UHF electronic ballast is a full 1000W DE EL UHF fixture. The Dimlux Expert Series 1000W DE EL UHF is a complete fixture including the Ultra Optics reflector. This reflector is designed according to the Single Bounce Clear Sight (SBCS) principle and is equipped with Miro Silver mirrors. As a result the highest possible efficiency (98%) of all available horticulture reflectors is achieved.

Provided with adjustable side reflectors for better overlap and to minimize wall losses. Due to the open design of the reflector the lamp is passively cooled which is a benefit for the life and efficiency of the lamp. The nanotube fixtures come with 2x50mm sockets which can be used to significantly reduce the room temperature by blowing 200m3/hour of cool air through each fixture. There are also optional add-on reflectors available which be placed to minimize the wall loss even more. This reflector is replaceable.

better than sunlight

By using a Nanotube the air can be extracted in parallel from the fixture, the lamp will always maintain the ideal temperature in order to maximize efficiency and life span. It is possible to achieve 20% lumens boost, this is only possible if the lamp is actively cooled.
