energy efficiency stogger LED vs HPS SON-T

In turf lighting practice the distribution of assimilation light within the grass growlight market is one of the most discussed issues. Since lighting costs, and thus energy, do not seem to stop increasing, an efficient use of assimilation light is of considerable importance for fieldmanagers. Many suppliers still use HPS SON-T. We focus at applying Mechatronix LED grow lights. Why did we made this decision?
Morphologic faster rooting and stronger vegetative growth
Higher light level possible, shorter treatment
Initial investment payback period <3 years
Energy efficient. Limited main connection necessary
70% light efficiency
Energy efficiency of 3.5 µmol/J
10 years warranty, maintenance free
World-class optics; even light distribution for homogeneic growth 
State-of-the-art technology; allows to profit from new developments
Dynamic lighting: soft start/stop, like the sun
Creates low heat. If heat is needed, burning gas is > 2x cheaper
Morphology not steerable by spectrum
Higher light level not possible, because of tipburn
Limited initial investment
Energy intensive. Requires industrial main connection & feed lines
35% light efficiency
Energy efficiency of 2.1 µmol/J 
Replace lamps every 3 years, maintenance required
No optics; uneven light distribution resulting in "grass growth spots" 
End of life technology
Static lighting: on/off
Creates a lot of heat: high inefficiency and risk of tipburn

Why not use HPS SON-T?

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, but very limited lifetime technology of HPS SON-T lamps.

Today it is clear that the future of turf assimilation lighting has completely turned in the direction of LED technology. The most important cost driver of any grass grow solution is energy efficiency. Due to it's proven track-record, the only way to go is a LED powered solution. The cost savings make sure that within 2 years a LED system is cheaper than SON-T.

10 year LED warranty

We designed our Booster's with more than just another LED grow light. We used the Mechatronix Coolstack®, with a market leading efficacy up to 3.6µmol/J, as it is a state-of-the-art grow light platform with an unprecedented level of technology and vision in it. As an example, we equip our Booster's with the first sustainable LED grow light on the market. With a 10 year warranty and LED life time of 75.000 lighting 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, the CoolStack® is designed in such a way that the LED grow light engines can be replaced and updated over time.
Did you know that the LED engines 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 a LED lamp after your warranty period when you want to upgrade to the next level of market efficiency in grow lights while you could do that with just a small part of the cost?
This is how we contribute, not only in your current investment, but also securing your durable future!

Cost Calculation Example

We provide grass grow light solutions for the lowest cost of ownership. To demonstrate in practice what that means, we have made a cost comparison calculation example below for HPS SON-T vs LED.
The calculation is based on a closed stadium like the Johan Cruijff Arena with a very minimum of sunlight all-year long. In a more open stadium or at different kWh rates, savings are different. Contact us for a cost calculation for your specific situation.
SON-T - 200 m2 grass @ 410 µmol/s/m2
Initial investment: HPS SON-T (2.100 µmol/s)
€ 8.200
Energy consumption per year (€ 0,20/kWh)
€ 41.519
HPS SON-T replacement costs each 18.000 hours

Total costs after 3 years
€ 135.711
Total costs after 5 years
€ 220.666
Total costs after 10 years

Stogger LED - 200 m2 grass @ 410 µmol/s/m2
CoolStack® LED equivalent (3.485 µmol/s)
€ 27.200
Energy consumption per year (€ 0,20/kWh)
€ 19.200
No LED replacement costs: 10 year warranty
