CoolStack® - MORE than just an HPS SON-T replacement!

09 April 2020

Compact and extremely powerful – that is in a few words what the CoolStack® LED grow lights stand for.
While the efficiency and technology of HPS SON-T grow lights has stabilized over years, the efficiency of LED grow lights moves up every year.
Just a few years ago we could still discuss if LED grow lights would offer a major advantage over the well-known and proven technology of HPS SON-T lamps.
Today it is clear that the future of horti assimilation lighting is completely turning in the direction of LED technology.

Horti LED grow light

This 4 new variations of the CoolStack® make the world different:

  • CoolStack® LE – Up to 1820µmol from 530 watts – efficacy 3.5µmol/J
    An absolute energy saver while delivering the same amount of light as a 1000 watt HPS SON-T lamp
  • CoolStack® HO – Up to 2070µmol from 600 watts – efficacy 3.5µmol/J
    The balance between energy saving and more light – While delivering 12% more light than a 1000 watt HPS SON-T, growers still save 40% of energy
  • CoolStack® BOOST – Up to 2950µmol from 880 watts – efficacy 3.5µmol/J
    Reduce your number of needed grow light per area and save the related cost, best price per micromole of light deal
  • CoolStack® MAX – Up to 3520µmol from 1025 watts – efficacy 3.5µmol/J
    For light loving crops – When the aim is not to save energy but to get more light, this is the way to go – 90% more light than a 1000 watt HPS SON-T for the same energy!

The CoolStack® is more than just another LED grow light – it is a state-of-the-art grow light platform with an unprecedented level of technology and vision in it.

As an example discover how we made the CoolStack® the first sustainable LED grow light on the market.
With a life time of 75.000 burning hours this stand equivalent to 20 years of use at a yearly rate of 3.600 hours of deployment.
Of course in that time the technology and efficiency of LED grow lights will drastically change and improve, and your energy cost is one of the major aspects.

Efficiency SON-T HPS vs LED

Therefore we have designed the CoolStack® in this way that the LED grow light engines can be replaced and updated over time.
Did you know that the LED emitters only count for 35% of the total cost of a grow light, and that the expectations are that this percentage will further decline over time when the LEDs become cheaper?
So why would you throw away 100% of your investments after a few years when you want to upgrade to the next level of market efficiency in grow lights while you could do that with just a part of the cost?
This is how we contribute, not only in your current investment but also in your future!
