Vertical Farming LED Grow Lights
Plant Factories, Vertical farms, Indoor Farming,… either fully automated or manual, their success in many cases depends a lot on the ideal LED grow light solution.
LED as technology fits of course ideal with the basic needs of multi-layer vertical farming.
Few heat allows limited space between the lamps and the crops leading to a more efficient space occupation.
Much lower power consumption compared to traditional light technologies has made that plant factories today are almost uniquely equipped with LED grow lights to reduce the operational cost.
While most of the LED grow lights bars look rather similar, the differences couldn’t be bigger…
For those who have been running a vertical farm already for a few years it is all crystal clear today – it is all about healthy plants, your capex and opex!
The CoolGrow® Linear
“A linear LED grow light bar full of surprises” this is how you best describe the CoolGrow® Linear.
Besides a market leading light efficiency, this vertical farming grow light platform is foreseen from a bunch of sophisticated features and options what makes implementation in your farm so much more practical.
Light spectra in function of your goals
A “one spectrum server all” is never the ideal approach.
Mimicking the sun light maybe will deliver you healthy plants, but in most cases comes with an operation expense on electricity consumption which is completely unrealistic.
Therefore we have developed a wide score of grow light spectra for plant factories, each with its specific purpose and with an absolute balance between targeted plant growth and optimal light efficacy.

Market leading light efficacy
A specific spectrum is not only important for specific growth results.
It also allows you to work at an absolute maximal light efficiency, which at the end determines more that 50% of you annual costs to grow in a vertical farm.
The impact of light efficiency is in many times seriously underestimated.
See the year-round production with continuous lighting, the efficacy of the grow lights is even more important than in a greenhouse.
Take an average crop with 16 hours of light per day, that makes roughly 5800 burning hours of your lamps in a full year.
Numbers tell more than words…
A canopy with lettuce – light level 200μmol/sm²
- Lamp 1 - Light efficacy 2.3μmol/J
You will consume 86.96 watts per m² per hour
Annual consumption per m² = 5800hrs x 86.96W = 504KW
At a cost of 10 cents per KW that makes 50.4€ per m² - Lamp 2 - Light efficacy 3.2μmol/J
You will consume 62.5 watts per m² per hour
Annual consumption per m² = 5800hrs x 86.96W = 362.5KW
At a cost of 10 cents per KW that makes 36.25€ per m²
Take in account that a square meter of canopy at 200μmol/sm² light level costs you around 120€.
That’s 17.14€ per m² if you depreciate it at 7 years.
Conclusion
The focus in lighting for vertical farming should clearly be at the opex and energy consumption side, more than on the capex and depreciation.
Just on energy you see already that system 1 compared to system 2 cost you 14.15€ per square meter per year more on energy, that’s a 39% higher energy bill.
