Frequently Asked Questions
Do you have questions about the LED grow lights of Oreon? Do not hesitate to contact us, we are happy to help you. Below you will find the most frequently asked questions.
What is the consumed power of the LED fixture?
The wattage of the Dutch Powerhouse 'Empress' is 670W, the wattage of the Dutch Powerhouse 'Monarch' is 1010W, regardless of the chosen spectrum. Read the Technical Datasheets in the Download Center for more technical information.
For which voltage ranges are the LED fixtures suitable?
The Dutch Powerhouse 'Empress' is suitable for the voltage range: 200-480 VAC (at 3.5-1.5 amps, 50-60 Hz). The Dutch Powerhouse 'Monarch' is suitable for the voltage range: 230-480 VAC (4.5-2.2 amps, 50-60 Hz).
Can the LED fixtures be used in a humid environment?
The LED grow lights of Oreon are completely dust and waterproof and IP67 certified. The LEDs are protected by a glass cover with an anti-reflection layer against light reflection and light absorption. The LED fixtures can be cleaned with a high-pressure cleaner.
Why do the Oreon LED grow lights create less shade?
Thanks to the active water-cooling system, the fixtures are very compact. The fixture is smaller than a traditional HPS fixture or comparable LED fixtures and still has a high light output and efficiency. In addition, fewer fixtures (and therefore less shadow effect) need to be hung in the greenhouse to achieve the same light level. Due to the compact size of the fixture, there is minimal shading and natural sunlight can be optimally used.
In which circumstances can the LED grow lights perform optimally?
The LED fixtures work optimally at an ambient temperature between 0°C / 32°F and 45°C / 113°F and a relative humidity of > 95%. The flow and water pressure for the Dutch Powerhouse ‘Empress’ is 21 l/min and 1.5 bar and for the ‘Monarch’ 25 l/min and 1.5 bar. The optimum temperature of the water at the input into the first fixture in a string is 4°C / 39.2°F above dew temperature. The output at the last fixture in a string, the optimum water temperature is max 45°C / 113°F.
How can the gained heat be reused?
Per LED fixture, ± 275W from the Dutch Powerhouse ‘Empress’ and ± 270W from the Dutch Powerhouse ‘Monarch’ are extracted in low-grade heat and dissipated via a closed water circuit. Low-grade heat can be used for various purposes. It can be upgraded in a heat buffer to high-quality heat via a heat pump or be removed from the greenhouse via a dry air cooler. The water-cooling system is unique per grower.
What warranties, certification and delivery options are included with the LED grow lights?
The LED fixtures have a 5-year warranty. We would like to refer you to the General Terms and Conditions for the full warranty conditions.
The LED grow lights comply with the following certification: cMETus listed (ANSI / UL + CSA), CE, UL 1598 - LVD 2014/35 / EU, CSA C22.2 No. 250.0-08.
Other materials such as cabling and suspension brackets are not supplied as standard, but we can include these in the quotation at your request.

Optimal use of day light?
It is possible with LED grow lights of Oreon. Despite the high light output, the fixture is smaller compared to HPS fixtures or comparable LED fixtures. As a result, less shading occurs and natural light is better utilized.
