How to Choose the Right Lighting for Your Greenhouse

Lighting | 17 September 2021

As summer comes to an end, many greenhouse owners are starting to look at their options for effective lighting systems. Whether you are looking for a brand-new LED system or HPS system, there are many considerations to keep in mind to ensure that you are getting the best solution. As a team of experienced agricultural electrical contractors, the team at BNR Electric understands how beneficial the right system can be for your greenhouse crops. That is why we have created a guide to help you understand how to choose the right lighting for your greenhouse.

How are LED lights used in agriculture?

What to Consider When Choosing a Greenhouse Lighting System

To ensure optimal growth conditions and light coverage, consider the following:

The Type of Light

When it comes to greenhouse lighting systems, HPS and LED systems are the most popular choices for crops. HPS systems provide bright and intense light that makes them suitable for most types of crops and plants. In addition to their brightness, HPS systems produce extra heat, making them a great choice for cold environments with harsh winters. LED systems are a newer option for greenhouses known for their impressive energy efficiency and reduced maintenance requirements. The only drawbacks to LED systems are that they do not produce as much heat and do not produce the same intensity as HPS systems.

Your Light Level Requirements

Most greenhouses are designed to make use of as much natural light as possible, reducing the amount of supplemental light required. Be sure to measure the amount of natural light your greenhouse receives during the day as this will help you determine how many bulbs and light fixtures are required.

Potential Obstructions and Shadows

Any hanging object in your greenhouse will cast a shadow, preventing light from getting to certain crops. When adding light fixtures to your greenhouse, it is important to ensure that they are not creating shade that blocks out natural light.

Electricity Requirements

Before installing any lighting systems for your greenhouse, you will need to determine that you have enough power. For the best results, have a licensed electrician examine your wiring and electrical panel to determine if you have enough power for your desired systems.

Fixture Efficiency

Energy costs are typically the second greatest expense for greenhouses, just behind labour. Greenhouse lighting can be expensive, so it is worth noting how efficient or inefficient a lighting system is. This will help you determine how much you can expect to spend on energy costs each week, month, and year.
