Analysis of Driving Factors, Opportunities, and Challenges in the Development of the Plant Supplemental Lighting Equipment Industry

01 Overview of the Plant Supplemental Lighting Equipment Industry

Plant grow lights are artificial light sources that stimulate plant growth by emitting electromagnetic spectra suitable for photosynthesis. Plant grow lights are generally used in applications lacking natural light or requiring supplemental lighting, providing a spectrum similar to sunlight or one better suited to the needs of the cultivated plants.

As one of the main factors affecting plant growth and development, spectrum, luminous intensity, and photoperiod all influence plant growth and development.

Plant supplemental lighting equipment is commonly used in greenhouses, vertical farming, plant factories, and home gardening. Currently, high-value agricultural products such as vegetables, fruits, and flowers in developed countries are mainly grown in greenhouses, using artificial light sources to regulate the light environment. For example, countries like the Netherlands in Europe have already applied plant supplemental lighting in modern agricultural production, achieving significant economic benefits.

In recent years, driven by rapid technological advancements and government policies, many lighting companies have expanded into horticultural lighting, making the plant supplemental lighting equipment sector one of the fastest-growing segments.

02 Global Market Drivers for Plant Supplemental Lighting Equipment

A. Growing global demand for fruits and vegetables, coupled with a gradual decline in per capita arable land

The population of emerging market countries continues to maintain a strong growth rate, and the world's total population maintains a steady growth trend, which also promotes the continuous rise in market demand for fruit and vegetable agricultural products. At the same time, the improvement in people's living standards has promoted the adoption of healthy and scientific dietary concepts and the improvement of dietary structures. The proportion of consumption of crops such as vegetables and fruits is gradually increasing, thereby promoting the development of the fruit and vegetable industry as well as the plant grow light industry.

Global and Chinese vegetable production has maintained steady growth in recent years, rising from 1.05 billion tons and 530 million tons in 2015 to 1.09 billion tons and 560 million tons in 2019, with compound annual growth rates (CAGR) of 0.9% and 1.2%, respectively. In the future, driven by continued global population growth and improved living standards, global and Chinese fruit and vegetable production and demand will continue to show a stable upward trend. However, global per capita arable land area is on a continuous downward trend, decreasing from 0.188 hectares per person in 2015 to 0.182 hectares per person in 2019, and is projected to decline at a CAGR of -0.6% to 0.177 hectares per person by 2024.

Population growth and the reduction of arable land require higher yields per unit area, thereby strongly driving demand for plant supplemental lighting equipment that accelerates growth and boosts production. Plant supplemental lighting equipment can promote photosynthesis in low-light or lightless environments, effectively accelerating plant growth, shortening the cultivation cycle of fruits and vegetables, improving their quality, yield, and flavor, fostering the development of the fruit and vegetable industry, meeting growing consumer demand, and helping address issues such as food supply and food safety.

B. Growing demand for home gardening

As household incomes rise and living standards improve, home gardening is gradually gaining popularity, with green ecology becoming an integral part of people's lives. In the United States, where there are many gardening enthusiasts, nearly 80% of households grow food or flowers at home, with each household spending an average of over $550 annually on gardening. The proportion of young people under 35 in this group is gradually increasing, exceeding 30%. In addition to planting various plants in their yards, more and more Americans are willing to invest more money in indoor growing equipment. On the other hand, the outbreak of the COVID-19 pandemic in early 2020 also promoted the development of the home gardening market.

Due to the pandemic, people have been spending more time at home and engaging in home activities such as home gardening. Balconies, backyards, and rooftops have become popular places for growing vegetables and green plants. Growing simple vegetables at home not only brings joy and allows you to enjoy the pleasures of rural life, but also helps reduce the risk of infection associated with going out for shopping. For gardening enthusiasts, providing suitable plant grow lights is often necessary to promote better plant growth. This is especially important in indoor growing environments with relatively weak light. LED grow luminaires, characterized by low power consumption, high luminous efficacy, low heat generation, and compact size, have been widely used in home gardening lighting applications. They can be used in household plant table lamps, home plant growing racks, and home vegetable growing machines. With the rise of global home gardening and increased awareness of gardening consumption, the prospects for home gardening lighting applications are promising.

C. Rapid development of modern facility agriculture

With the rapid development of science and technology, the connotation of facility agriculture is becoming increasingly rich. Various models and concepts such as greenhouses, plant factories, vertical farming, and soilless cultivation are gradually maturing. Facility agriculture features high technological content, intensive management, and high economic efficiency, making it one of the important symbols of modern agriculture. The global area for greenhouse vegetable cultivation increased from 415,000 hectares in 2014 to 497,000 hectares in 2018. In addition, the rapid development of plant factories in recent years has brought new momentum to modern agriculture. Plant factories are considered an important approach to addressing issues such as resource scarcity, insufficient labor force among the new generation, rising food demand, and the abuse of chemical fertilizers and pesticides. They are also a key means to achieve food self-sufficiency during future aerospace engineering exploration, receiving widespread attention from countries around the world.

In modern controlled-environment agriculture systems, the light environment is one of the indispensable physical environmental factors for plant growth and development. Regulating plant morphogenesis through light quality adjustment is a key technology in facility cultivation. When environmental conditions such as carbon dioxide, water, nutrients, temperature, and humidity are fixed, the photosynthetic photon flux density between the light saturation point and the light compensation point of a specific plant directly determines its relative growth rate. With in-depth research on the spectrum, it has been found that light in different wavelength bands has different effects on various growth stages of plants. Supplemental lighting equipment can extend effective illumination time as supplementary lighting, completely replace natural light to promote plant growth in plant factories, and thoroughly solve the problem of dependence on weather during the seedling stage, allowing reasonable scheduling based on seedling delivery deadlines. Through the use of supplemental lighting equipment, the rate of plant photosynthesis and the efficiency of light sources can be better mastered, thereby controlling the speed and quality of plant growth. Therefore, the rapid development of modern controlled-environment agriculture cannot be separated from the support of plant supplemental lighting technology, and the increasingly diverse agricultural planting scenarios and continuously improving planting requirements have also promoted the further development of the plant supplemental lighting industry.

04 Challenges Facing the Industry

A. The industry is in its early development stage, with low market maturity.

Currently, the domestic plant supplemental lighting equipment industry is still in its early stages of development, with low market maturity. Especially in the field of low-power plant supplemental lighting products, the competitive landscape remains unclear. Low-power plant supplemental lighting products have relatively lower requirements for production processes and technical standards. Some smaller-scale manufacturers adopt low-price strategies to increase market share while neglecting product quality standards, which may trigger vicious price competition and hinder the long-term development of related domestic industries.

B. Lack of unified industry standards

The plant supplemental lighting industry is in a period of rapid development, and relatively unified industry standards have not yet been formed. Therefore, manufacturers must design targeted product solutions based on the different product specifications of luminaire manufacturers, resulting in a wide variety of LED driver / power supply and luminaire products on the market, which in turn leads to a certain degree of waste of R&D and production resources. The lack of unified industry standards has become an unfavorable factor affecting industry development.

05 Barriers to Entry for Traditional Luminaire Manufacturers

A. Technical Barriers

Unlike traditional luminaires for indoor lighting, public lighting, and landscape lighting, plant growth lighting equipment requires high photosynthetic photon flux to meet the needs of plant photosynthesis, so its LED driver / power supply generally has higher power. The higher the power of the LED driver / power supply, the greater the difficulty in circuit structure design and thermal structure design. In addition, plant growth lighting equipment is used in environments with large temperature differences, high humidity, high corrosion, lightning surges, electromagnetic interference, and significant grid voltage fluctuations. It needs to meet special lighting requirements such as high stability, high reliability, specialized light distribution, and high photosynthetic photon flux, while also meeting requirements for energy saving, safety, and environmental protection. The design of plant growth luminaires differs significantly from traditional luminaires. Therefore, traditional luminaire manufacturers face certain technical barriers if they wish to enter the plant growth lighting field.

B. Customer Resource Barriers

Currently, the main application markets for plant supplemental lighting are concentrated in developed countries such as Europe and the United States. Downstream customers are mainly large-scale facility agriculture product brand owners, and the business model is primarily ODM. These customers mainly value strengths such as product quality, long-term stable supply capacity, and assistance in product upgrades for downstream customers. Customers generally need to conduct thorough evaluations before determining their suppliers. They will only add or change suppliers if the original supplier encounters major quality issues or fails to meet supply demands in terms of production volume and price. The certification process for suppliers by downstream customers consumes significant time and cost. New entrants find it difficult to break through the commercial reputation and cooperation habits formed over many years. Therefore, traditional luminaire manufacturers often face high barriers to customer resources when attempting to enter the plant supplemental lighting field.

C. Product Differentiation Barriers

Plant supplemental lighting belongs to specialized lighting. Its production and application technologies, product characteristics, application fields, and sales channels differ significantly from traditional lighting. Plant supplemental lighting emphasizes application scenarios; scenarios vary by planting region and plant growth stage. R&D and product teams must have extensive industry experience in plant supplemental lighting and a thorough understanding of the full plant growth cycle to develop products aligned with downstream demand. Traditional luminaire manufacturers have limited understanding of plant supplemental lighting application scenarios and must incur high time and R&D costs to enter this field.
