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

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.
With over seven hundred hectares of installed lamps in greenhouses and grow rooms, the CoolStack® became the reference for LED top lights in Europe and gained the trust of many leading growers around the world.

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

• CoolStack® MICRO – Up to 1276µmol/s from 312 watts – efficacy 3.08 µmol/J - 4.03 µmol/J

Low power, high efficiency with light weight
Daisy-chain style of up to 4 lamps

• CoolStack® COMPACT – Up to 2640µmol/s from 680 watts – efficacy 3.5 µmol/J - 4.03 µmol/J

25% more light with 35% HPS SON-T energy saving compared to a 1000W HPS SON-T
Best deal for more light with less energy
Daisy-chain style of up to 2 lamps

• CoolStack® BOOST – Up to 3943µmol/s from 1048 watts – efficacy 3.5 µmol/J - 4.03 µmol/J

75% more light with same energy
HPS SON-T drop-in replacement
Upscales your crop production capacity

• CoolStack® MAX – Up to 5104µmol/s from 1251 watts – efficacy 3.5 µmol/J - 4.03 µmol/J

Energy & price efficient
Minimal number of lamps & cost per installation

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.

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!
