Grow Room LED Grow Lights

Greenhouse LED Grow Lights

When you look up in modern lighted greenhouses in West Europe you have for sure seen our lamps already.

Already back in 2017 we came on the market with the first LED grow light able to replace a 1000 watt HPS SON-T.

In that time most LED grow lights still looked like a light bar and were placed on a bunch of extra C-profiles in the greenhouses, creating tremendous investments per meter and a lot of extra shadow on the crops.

We decided to do it different…

Our LED grow lights for greenhouse supplemental lighting are made with a lot of vision. We aim in each crop and growers project for an optimum balance between investment and operational costs.

We don’t believe in a “one product serves all” – each region, each crop, each growth stage,… has it’s specific ins and outs you need to be aware of in order to provide the perfect grow light product.

While in one region energy is almost for free, in another region energy can be the major cost driver in a grow light project.

Therefore we have developed a wide range of LED grow lights for greenhouses, each with its specific purposes and benefits.

In the majority of our projects you will see our flagship the CoolStack® in LED or hybrid lighted greenhouses.

Strawberry projects with LED Grow Light CoolStack®

The CoolStack® is the most powerful and modular LED grow light which is today available on the market.

Directly placed under the greenhouse trellises and with and ultra-small width, we guarantee a minimum of extra shadow on the crops.


What makes the CoolStack® the ideal LED grow light for your greenhouse project:


3 different power and light outputs guarantee the ideal match for the needed light level of your crops with a minimal number of light fixtures and an ideal light spreading.


A good example of the benefits of this approach is our CoolStack® Boost system in strawberry greenhouses.

With just 2 lamps of the CoolStack® Boost per 8 meter trellis for an early-late strawberry cultivation we have reduced the investment cost per square meter for the growers with over 25%.

The ideal light distribution per crop with intelligent lens beam angle design


There are tremendous differences between a high wire crop project where the lamps are less than 2 meters away from the top of the crop and for example a lettuce project with 4 meter from lamp to crop.

Just spreading the light in the widest way is of course the easiest solution and gives in many cases a good even light spreading, but is far from ideal with regards to light penetration in the crop.

We have developed a wide score of different beam angles and beam patterns to give you the ideal light distribution and deepest crop penetration per project.

Upgradable LED engines for a sustainable future


Over the last years extremely big steps have been made in the efficiency of LED grow lights, what has led to an exponential increase of LED grow light application in greenhouses for a wide range of crops.

Motivations of the growers though can have wide varieties with each its specific aims

  • Saving energy compared to HPS SON-T installations is probably the most common driver today for growers to invest in LED grow lights – as of today we can replace the light level of a 1000 watt HPS SON-T lamp with just 530 watts of LED grow light energy or a saving of 47%.

  • More light for the same power consumption – certainly light loving crops like tomatoes do profit a lot from extra light for the same energy cost – while a modern HPS Son-T lamp of 1000 watts produces 1850µmol of light, our new CoolStack® MAX produces now up to 4380µmol out of the same power, or 130% more light for the same power.

  • Better temperature controls during growth – one of the main disadvantages of growing with HPS SON-T lamps is the extensive heat these lamps produce.
    A 1000 watt HPS SON-T generates 700 watts of heat – more specific the biggest portion of this heat goes to radiated heat which leads immediately to ambient temperature and leaf temperature increase. While growers aim for higher light levels, this heat can become too much for a good controlled production. In these cases a hybrid of full LED installation can be the way to go.

  • Specific crop improvements during various growth stages.
    One of the biggest advantages of LED grow lights is the potential of steering plants with specific supplemental light spectra.
    In this way germination can be speed up, a stronger root production can be achieved or stretching of plant can be avoided.

Although the efficiency of LED grow lights highly surpasses these of traditional HPS SON-T lamps today, the end of further improvement is still far away.

Over the next years more big steps are expected in potential light production per watts of energy.

Therefore we have develop our grow lights in this way that the light engines can be individually upgraded without the need to re-invest in a complete new grow light installation.

Why would you upgrade your grow light LED engines over time?

  • When you would save more cost of energy than what the upgrade of the LED engines would cost over time.
    This is mainly the case for growers who pay high energy prices like in west and south Europe and work without a CHP, and crops which run with many lighted hours per season like tomatoes, cucumbers, bell peppers,…

  • When your crops would benefit more from the extra light you get after an upgrade than the cost of upgrade.
    Mainly light loving crops which still produce more at higher light level than the original installed light level show great profit of this.
    Take for example a tomato grower who installed a light level of 180µmol/sm² in 2018 at an efficiency of 2.5µmol/W.
    This grower could today move for the same power consumption to a light level of 250µmol/sm² with a simple upgrade.

  • When in the future other light recipes would be proven to be much more efficient.

CoolStack® LoB-holder-lens assembly steps

Longest life time and lowest light decay over time.


It maybe doesn’t show from the outside, but the CoolStack® is a true masterpiece of technology.

Where most LED grow lights use simple cooling principles like a block of aluminum, water which runs through the chassis or fans which blow, the heart of the CoolStack® is a sophisticated passive heat pipe and stack fin cooler.

This technology, which is implemented in a lot of high end devices like lap tops, iPads and smart phones, guarantees you the best thermal management of the LEDs on the market.

The light efficiency, the life time and the light decay (how fast or slow the light reduces over time) are all directly related to the LED temperature of the grow light.

So with the CoolStack® which runs the internal LEDs as cold as possible, you as a customer obtain a grow light which lives longer, has a higher efficiency of light per watt and maintains his light at a higher light level over time.

With a life time of 75.000 hours L90B50 and a warranty of 10 years there is quality wise nothing even close to what the CoolStack® offers.
