Specifications
RA WaterCooled Series
RA-250
Our smallest water cooled top light is a 250W COB. As the frame is designed to be as small and efficient as possible, it is not possible to be cooled by air. Water cooling allows to remove almost all the heat out of the room for a better climate management.
The RA-250 is designed for use in greenhouses and climate chambers.

Different spectrums for different needs
Parus has spent years of research to optimize on visual and yield quality
Specific spectrums created for specific needs from your plants in your vertical farm, indoor, or greenhouse environment. Parus light spectrums are designed for all plant stages, letting you control the seasons or density of your crops.
From a visual white full and broad spectrum with 3.3umol/j to specific adjusted spectrums based on efficiency in your greenhouse of up to 4.0umol/j. Parus has a solution to all situations. Our scientists are working daily on improving the right colors in our spectrums.
Making the efficient visual white!
RBW or RBWFc with controllable far red is our best and most used light spectrum. Balancing between the ultimate evaporation and photosynthesis while keeping the plant vegetative and generative growth conditions as close to nature as possible. Parus made the visual white spectrum as efficient as possible by lowering the yellow green to an acceptable range. We offer this spectrum with and without dimmable far red.
Fully pink growlight
The most efficient spectrum balanced for the greenhouse or highly precision climate controlled indoor situations. This spectrum generates up to 4umol/j and is available with or without a far red dimmable peak.
Pink to the eye with a white reflective tone
RBS is the best all round spectrum while still keeping efficiency in mind, the red/blue ratio is perfect for all sorts of growth indoor and in combination with natural lighting. By adding some green/yellow this spectrum is light pink for our eyes making the work area acceptable to work in for longer times in indoor situations and will have no effect on the crop colours in the greenhouses with daylight.
Be in control, high blue or spectrum controlled dimmable red and blue
Need more compact young plants, or want to research yourself? RBC is the right choice allowing you to control the ratio of red and blue. Our fixtures come in two versions for this spectrum, dimmable red and blue, or a fixed high blue allowing you to make compact plants. Ask one of our researchers to support you making the right choice.
Have your own spectrum needs? Let our scientists support you to make your own.
If your company has done its own research, or you have specific needs, let our scientists support you and we will make it.
Top lighting may have two dimming channels, while linear lighting can have 3 dimming channels to support your own research. Once you found the right spectrum Parus can produce this as a fixed spectrum.
