Heat from lighting

The switch from HPS (High Pressure Sodium) to LED lighting is more than just choosing to use a different fixture type. The energy balance in the greenhouse changes considerably and so additional cultivation measurements are required.

The first chapter of the e-book “How artificial lighting can optimize efficiency” is zooming in on the various types of heat coming from lighting, and the differences between HPS and LED lighting. After reading this chapter, you’ll understand everything about how heat – which is produced by lighting – affects the temperature and climate in the greenhouse, and therefore the plant’s energy balance. You’ll also know exactly what a potential switch to LED lighting means from an efficiency perspective for your own crops.


Whitepaper about LED lighting: Energy balance changes significantly when switching to LED lighting


Many growers are facing extremely high energy prices at the moment and are looking for ways to reduce their energy consumption. If you have thought about making changes to your lighting strategy and improve plant health while saving energy in the process, you may also consider the switch from HPS (High Pressure Sodium) to LED lighting. But a switch like this involves a lot more than just choosing to use a different fixture type. Not only the temperature and the climate in the greenhouse changes, also the plant’s energy balance changes considerably when switching to LED lighting, and this means also that additional cultivation measurements are required.

In terms of the energy balance, light is one of the most important energy sources. By paying more attention to lighting as part of the Plant Empowerment principles, it’s possible to maximize efficiency by creating the optimum balance of light intensity, energy consumption and crop growth, resulting in the highest possible yield per square metre.

About the e-book

To understand more about the possible ways to improve the distribution and uniformity of light in your greenhouse and learn what the best lighting strategy is for your crops, we’re published an e-book which is going more into depth about the role of lighting in your greenhouse. This e-book is very useful for all kind of growers around the world with insufficient or only just little knowledge about lighting, because the more you understand about this topic, the easier it is to spot new ways in which you can save energy without compromising on crop performance.

The e-book is written by several grow-light specialists from Plant Empowerment Implementation Partner Hortilux Schréder, who are keen to share their expert knowledge around the world. These specialists are willing to help all growers using artificial lighting more effectively and obtain the maximum results out of their usage of grow light (LED, HPS and hybrid).
