CoolStack® LED Top Light Greenhouse cultivation Passive cooled

The CoolStack® is a state-of-the-art high precision LED grow light for top lighting applications in greenhouses and grow rooms.
With a market leading output up to 1.950µmol/s it is the ideal LED grow light alternative for HPS SON-T lamps.

The CoolStack® is composed out of 4 individual CoolGrow® horti LED engines, each under its individual optic TIR lens.
By altering the lenses the light distribution can exactly be adapted to give the best fit for your greenhouse or grow room conditions.
The lenses are available in beam angles of 60 degrees, 75 degrees, 90 degrees, 105 degrees and 120 degrees, with specific beam shapes like batwing technology and high-technology features like anti-glare option which creates a higher level of comfort while working under the grow lights.

Your inputs with regards to the greenhouse or grow room practical setup in combination with the required PPFD light levels and spectrum is translated by our engineers to the ideal setup in a light simulation plan.
By achieving a good distributed light level over the crops with a beam as narrow as possible, you don’t only achieve a higher PPFD level from the same lamps, but also gain tremendous on crop penetration rate.

11 validated growth spectra ensure the right light composition for your crop and growth stage.
We combine both narrow band spectra of LED grow emitters with broadband spectra to create a maximal trade-of on efficacy in combination with a good workable visual spectrum for the people.All details about our spectra you find here

Last but not least, the CoolStack® is much more than just another LED grow light system.
Foreseen from the most advanced cooling system on the market, a high performance cooler with 16 heat pipes and a low-weight stack fin structure, the CoolStack® guarantees by far the longest life time ever seen in commercial grade LED grow lights – 75.000hrs!

It is also the first grow light system designed from a point of view of sustainability.
A lot will happen in the next 75.000 hours you deploy our CoolStack in your greenhouse or grow room – and one thing is for sure, the efficacy of the LEDs will keep on raising over that time while the prices will reduce.
That’s why we made the system upgradable by just changing the LED engines – in this way you can upgrade your system over time to the next level of efficacy for just a fraction of the cost!
