Monarch

Dutch Powerhouse Monarch has a 1050 W or 1250 W driver and can reach a light output of up to 5000 µmol/s. This top lighting fixture is available in 4 variants. The 'Monarch High Efficiency' variant is recommended for high-tech greenhouse projects where sufficient height is available, so that a high uniformity is achieved with fewer fixtures. Due to its high efficiency, this fixture is also the best option for growers with a limited power capacity. 

The ‘Monarch Economic’ fixture has lower maximum light output (of up to 4660 µmol/s) and is interesting when less light is needed or when the energy price does not play an important role.

The ‘Monarch HPS replacement’ has a light output of up to 4110 µmol/s (1050 W) and can easily replace 1-to-1 an HPS fixture. This is the most efficient choice at a high energy price, when using an existing installation that produces at least 85% more light.

The fourth variant, the Monarch 'HPS replacement economic', has a lower maximum light output (up to a maximum of 3880 µmol/s) and is an interesting option when less light is needed or when the energy price is less relevant (lower initial investment).

All variants of the Dutch Powerhouse Monarch are actively cooled by water which offers many advantages. Fixtures can be mounted under the trellis and because of the compact design, less sunlight is being blocked in the greenhouse. The water cooling extracts the heat out of the fixtures and out of the growing area and offers the opportunity to reuse gained heat. This eventually results in a stable climate which is beneficial for the quality and the growth of the plants, but also offers a great advantage on the cooling installation as less cooling is needed (which automatically means lower running costs). 

Because what doesn’t heat up, doesn’t need to cool down.
