For years, the Resource Innovation Institute (RII) has been advocating for the adoption of high-efficiency light-emitting diode (LED) fixtures in controlled environment agriculture (CEA) operations. The benefits of LED lighting, such as energy efficiency and increased productivity, have been demonstrated through real-world data and use cases. As a result, regulators are now developing regulations and standards that will likely mandate the use of high-efficiency lighting systems. This presents a crucial opportunity for operations still relying on legacy lighting systems to make the switch to LED technology.
Development and Consequences of LED Adoption
The competition in CEA operations, particularly in the cannabis cultivation sector, has intensified in recent years. Profit margins have decreased significantly, and operators are realizing the importance of maximizing process efficiencies to remain viable. Energy bills constitute a substantial portion of total operating costs, making LED lighting an attractive solution to reduce expenses. LED fixtures can slash energy bills by 30 to 40% compared to traditional high-intensity discharge (HID) counterparts. Additionally, LED maintenance costs are generally lower, contributing to overall cost savings.
Advancements in LED technology have further enhanced their efficacy. Lighting control systems now allow growers to create crop-specific light recipes, ensuring the most efficient light delivery throughout the production cycle. Dimmability is a feature gaining popularity among regulators and standards providers, as it not only saves energy and costs but also allows growers to optimize their cultivation environment. Furthermore, dimming and spectral tuning enable growers to potentially increase crop yields and future-proof their facilities.
Carrots and Sticks: Incentive Programs and Regulations
Many CEA operations have already transitioned to high-efficiency LED lighting systems, often with support from utility incentive programs. However, as baseline efficiency increases and more operations adopt LEDs, these incentive programs are being scaled back or phased out. States are beginning to mandate LED lighting in new builds and retrofits, further pushing the industry towards energy-efficient solutions. As a consequence, the clock is ticking for operations to maximize the rebate and incentive value for adopting LED technology.
One example of regulatory developments can be seen in California, where the Statewide CASE Team aims to increase the minimum photosynthetic photon efficacy (PPE) for luminaires and lamps used in indoor facilities. This change would essentially mandate the use of LED lighting, leaving HPS lamps as non-compliant options.
Transition Tips for a Successful Switch
Making the transition to LED lighting requires careful planning and consideration. Growers need to account for factors such as heat load loss, especially in colder months when HID lights contribute to greenhouse heating. Collaborating with lighting suppliers to develop light plans, formalize installation and project details, and place orders in advance is essential for a smooth transition.
Interoperability is another critical aspect to consider when purchasing LED lighting systems. Ensuring compatibility with control systems can future-proof operations and ensure long-term cost-effectiveness.
Engaging with utility companies early in the decision-making process is crucial to accessing incentive programs effectively. Program rules may vary across utilities, so understanding the nuanced rules and requirements beforehand can prevent missed opportunities for incentives.
With real-world results showcasing the benefits of LED lighting systems, the time is ripe for CEA operations to switch to high-efficiency LEDs. By making the LED leap now, businesses can maximize utility incentives and rebates while positioning themselves for long-term success. LED technology not only reduces operational costs but also boosts crop growth, making it an indispensable tool for the future of controlled environment agriculture.
As Leora Radetsky emphasizes, the tunability of LED fixtures will enable growers to achieve more with less—a goal that aligns with the entire industry’s desire to operate efficiently and sustainably.
