LED Lighting Case Studies

Why Choose Senmatic LED Lighting?

LED lighting that offers dynamic control of light intensity and spectral composition, whilst enabling easy integration with climate control systems, is essential for today's growers. That is the reason why our LED fixtures have become a success, and that is also the reason why our customers have choosen one of our fixtures.  The case sudies show how customers came to the decision to use our LED fixtures, and how the decision has benefitted their business.

Tulips in Holland

Rainbow Colors and Horizon Flowers
Located in The Netherlands, Rainbow Colors and Horizon Flowers produce close to 100 million tulips each year. At the greenhouses, performance and flexibility are crucial - as is maintaining stable two-layer cultivation in winter. The companies were looking for a dynamic system with a focus on light efficiency and the possibility to provide each tulip variety with a different type of light.

Optimal control
The FL300 Grow is now installed throughout the entire greenhouses. For optimal light control, the FL300 system is combined with the LCC4 climate control system, which monitors all greenhouse parameters while controlling the various light recipes and light levels.
System trials revealed a unique advantage: the ability to provide each tulip variety with customized light recipes. Some tulips required stretching, while others needed color enhancing. The FL300 and LCC4 combination has proved itself up to the task.

Bas Karsten, CEO at Rainbow Colors says:
"After evaluating different LED manufacturers we chose the FL300 LED system from Senmatic. It won on three parameters: Price, light efficiency and the possibility to control the light."

Lettuce & Herbs

Spisa Smaker AB - former Swedeponic
Based in Sweden, Spisa Smaker AB is Europe's largest producer of growing herbs. Production on this scale requires serious electricity efficiency, and after testing a number of LED solutions Spisa Smaker AB chose to invest in the FL300 Grow from Senmatic.

No downsides
In a large full-scale demonstration, the FL300 enabled a 48% savings in electricity without compromising production gain or taste. For savings like this, growers might expect losses elsewhere, but not with the FL300.

Spisa Smakers UK's Managing Director Patrick Bastow states: "No, we didn't see any downsides. Nor did we see the need to increase the heating in the LED crops to cope with the loss of infrared heat that you normally get with HPS."

The Spisa Smaker installation is another example of a successful large-scale LED installation generating electricity savings while producing high-quality plants. Now in action in four different Spisa Smaker locations, each installation has a customized focus - from producing tasty, high-quality herbs to enhancing the red colour in specific lettuce varieties.

Ulf Jonsson, CEO at Spisa Smaker says:
"When the FL300 system was used at the same intensity as conventional HPS lighting, it generated electricity savings of 48%."

Potted Plants & Energy Saving

As one of Scandinavia's largest flower nurseries, PKM was seeking a solution to maximise electricity savings while maintaining a high plant quality. To achieve this, they turned to Senmatic.

For four growth seasons, PKM has tested the FL300 system. In 2011/2012 more than 100,000 Campanula flowers were grown with the following results:

  • Up to 50% electrical saving compared to 400 watt HPS system
  • Up to 35% electrical saving compared to new 1,000 watt HPS system

In 2014, the installation was expanded by 1500 m2, making it one of the biggest LED top light installations in the world.

Central control
The FL300 has three stand-out features at PKM. First the minimalist installation which is as simple as installing HPS. The second is integration where the LED fixtures are now fully integrated in the Senmatic climate control system. The third is plant quality: The plants are thriving in the 'new light' with the same or even better quality than with the old HPS system.

Erik Moes, CEO at PKM says:
"The big advantage of the FL300 is that we can control light intensity and spectral composition cen­trally or with a tablet PC. Then there's the huge electricity savings."

Tomatoes: The Hybrid Solution

Alfred Pedersen & Søn ApS
Alfred Pedersen & Søn ApS is the largest tomato grower in Denmark, growing 5 types of tomato on 12 hectares of land. Each tomato type carries specific growth requirements. The company sought a new solution to enhance production volume while maintaining quality.

High quality with the Hybrid solution
Growing tomatoes is a combination of producing a high kg/m² volume while keeping quality high all year round. Traditionally, tomatoes were grown with standard HPS light, but Senmatic offers an economical solution that unites the best of both worlds: The Hybrid solution. This solution combines heat radiation from conventional lights and the photosynthetic radiated light of the FL300 system. Together, the hybrid solution provides the capability to grow high-quality tomatoes without changing your entire system all at once.

The illustration shows that installing the FL300 system is as easy as installing HPS and existing cabling and rails can be utilized in the setup. And the benefits of the hybrid system are immediate: the installation tops up the installed lights with an extra 90 µmol/m²/s, stimulating efficient tomato growth and increasing yield and production.
