Greenhouse LED Grow Lights

CoolFin® LED Top Light Grow room high intensity Passive cooled

In most single layer grow rooms you will see our advanced CoolFin® LED grow light.

CoolFin® LED grow light

The CoolFin® is the most powerful and modular LED grow light for grow rooms which is today available on the market.
It’s unique cooling system and ultra-high efficiency makes that there is a very limited heat production coming out of this lamp, what makes it ideal for controlled cultivations in a closed room.The CoolFin® leads to an heat reduction of over 50% compared to traditional HPS SON-T lamps, which immediately leads to less need of extra cooling and the related energy cost, but also to a better controllable plant balance in your crop.

What makes the CoolFin® the ideal LED grow light for your grow room project:


2 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.


While most grow rooms in the past where equipped with light bars, we aim at reducing the number of light fixtures per area in order to achieve a lower overall cost per meter.
Also less cabling leads to a lower cost and an overall cleaner installation.

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


When your grow room is equipped with a minimum number of grow light fixtures, light distribution and light penetration in the plants becomes a point of attention.
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 depth of the crop.

Plant trials over the last years have shown that crops with a more complex morphology like high tomatoes, cucumber, egg plants and cannabis can deliver up to 20% higher production at the same light level when the light is deeper vertical distributed in the crop.

To achieve the optimal balance between even light spreading and deep distribution we have developed a wide score of different beam angles and beam patterns.

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 and cannabis do profit a lot from extra light for the same energy cost – while a modern HPS Son-T lamp of 600 watts produces 1100µmol of light, our new CoolFin® HO produces now up to 2070µmol out of the same power, or 90% more light for the same power.

  • Better temperature controls during growth – one of the main disadvantages of growing with HPS SON-T lamps in grow rooms is the extensive heat these lamps produce.
    A 600 watt HPS SON-T generates 420 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 or full LED installation can be the way to go.
    The CoolFin® HO produces just 190 watts of heat out of a 600 watt lamp, or 55% less than a tradition 600 watts HPS SON-T grow light.

    In grow rooms extra heat also means extra cost for cooling and the directly related investment and energy bill, so also from that side our LED grow lights outstand in an overall much lower cost for air conditioning both on capex and opex.

  • Specific crop improvements during various growth stages.
    One of the biggest advantages of LED grow lights is the potential of steering plants with specific 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 replaced without the need to re-invest in a complete 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 rotation like tomatoes, cucumbers, bell peppers, cannabis,…
    Certainly in grow rooms the importance of extreme high light efficiency is an absolute point of attention, even more than in a greenhouse.
    Take as an example a cannabis flowering room, where the capex to opex rate for LED grow lighting over a 5 year period is 30/70.
    So 70% of the cost comes from the operational cost mainly as a result of electricity consumption.
    If you can move from a light efficiency of 2.3µmol/J to a light efficiency of 3.2µmol/J, that would save you 28% of electricity cost for the same light level.

  • 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 cannabis flowering room installed a light level of 600µmol/sm² in 2018 at an efficiency of 2.2µmol/W.This grower could today move for the same power consumption to a light level of 850µmol/sm² with a simple upgrade and for the same power consumption.

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

Longest life time and lowest light decay over time.


It maybe doesn’t show from the outside, but the CoolFin® 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 CoolFin® 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 L90 and a warranty of 10 years there is nothing even close to what the CoolFin® offers.
