Lighting Market Reports

2025 Lighting Market Report

Growing together 

Hear from the sponsors of the Greenhouse Management 2025 Lighting Market Report, Hydrofarm and Photobio.

Growing enlightened 

More growers plan on updating lights in the next three years, but costs remain a concern.

Quest for quality 

CT Food 4 Thought is single-minded on consistency — and finds it in its choice of lighting solutions.

Measuring daily light integral for greenhouse production 

Daily light integral (DLI) is an important variable to measure in every greenhouse because it influences plant growth, development, yield and quality.

Added value 

Take advantage of rebates and incentives when planning greenhouse upgrades or new construction.

 


2024 State of Lighting Report

We're back! Philips is the sponsor of Greenhouse Management's 2024 State of Lighting Report.

The age of the LED: More growers are joining the luminaries as they transition to more efficient ways to light crops.

Decision-making tools: From efficacy to quality, the DesignLights Consortium provides lighting research for growers.

Offset costs: Energy-efficient upgrades often qualify for rebates and other incentives. Make sure you’re taking advantage of these programs.

Early adopters: LEDs were new to the market when Walters Gardens set up its first lighting trial. Now, 3 acres of greenhouse space are under LED lighting.

Red and far-red light: It’s important to know how red and far-red light act as a signal to plants in a greenhouse environment.

 

 

2022 State of Lighting Report

Sponsor letter: LED lighting plays a key role in addressing controlled environment agriculture challenges.

Scrutinize your supplemental lighting: Growers’ use of and interest in light emitting diodes (LEDs) have continued to climb. They cite efficiency as the No. 1 reason to make the switch from other methods of greenhouse lighting.

Fixed vs. dynamic light for indoor hydroponic lettuce: Tailoring the light spectrum for each growth phase.

Time for an upgrade?: Commit time and attention to a lighting plan to get the most out of your new system.

Power up: Keep up with power availability in your area, which has a bearing on your greenhouse systems, including lighting.

 

 

2021 State of Lighting Report

Sponsor letter: A note from Chris Hagedorn.

Research: LEDs continue their dominant run.

Supplemental lighting Q&A with Aaron Fields of Eden Green Technology: LEDs help this Texas grower improve yield and control crop morphology.

Comparing the performance and light output of horticultural lamps: Recent research at Rutgers University found that the efficacy and spectral output of various light sources used for horticultural applications differs substantially.

Leider Greenhouses’ supplemental lighting success: Elizabeth Leider shares why and how they use supplemental lighting at the 14-acre operation.

 

 

2020 State of Lighting Report

Sponsor letter: A message to the heroes of horticulture.

Give the green light: Greenhouse growers plan to flip the switch on new and improved supplemental lighting technologies in the next three years.

How 3 growers approach system add-ons: Choosing the correct lighting setup is among the most important decisions a commercial greenhouse grower will make.

How to properly estimate lighting costs: Estimating lighting costs and knowing how much light to use are key to turning a profit when using supplemental lighting.

Trial before error: Testing different lighting setups in your greenhouse has its advantages, but there are also some factors to be aware of in order to ensure accurate data collection and observations.

 

 

2019 State of Lighting Report

Embracing a new understanding of PAR: Research at Utah State University is transforming our understanding of photosynthesis and light.

Making way for the sun: Marc van Iersel of the University of Georgia talks about his research with light dimming and his new lighting control company, Candidus.
