Human beings have sustained the expansion of space and time development with the ingenuity of artificial lighting. Human production has increased by various request for of artificial lighting since the time of Edison particularly in the fields of agriculture, livestock and fishing industries
Grow lights is one such invention that represents the industrial revolution. This technology either attempts to offer a light spectrum similar to that of the sun, or to offer a spectrum that is more customized to the needs of the plants being cultivated. Outdoor conditions are imitated with varying colour, temperatures and spectral outputs from the grow light, as well as differing the intensity of the lamps. Depending on the kind of plant being cultivated, the stage of cultivation (e.g. the germination/vegetative phase or the flowering/fruiting phase), and the photoperiod required by the plants, a particular range of spectrum, radiant efficacy and color temperature are suitable for use with specific plants and time periods.
Grow light technology helps in stretching the hours of the natural daylight which additionally improves the health, growth rate and yield of the plants. Artificial lighting, such as high-pressure sodium lighting, LED lighting and plasma lighting can extend the obtainability of crops (throughout a season). There is an increasing awareness concerning the importance of alternative farming, due to the less availability of fertile agricultural land and increasing population, are the major factors anticipated to stimulate the industry demand.
The study analyses global grow lights market based on spectrum, technology, application and geography.
Partial and full are the two spectrums into which this industry is classified based on spectrum. Full spectrum light delivers useful light for photosynthesis across the 400 nm to 700 nm wavelengths, which is also referred to as Photosynthetic Active Radiation (PAR). Additional Far Red light (700 nm - 800 nm) influences plant growth and development (morphology). Full spectrum white light also provides comfortable lighting for workers within the space, which may allow growers to reduce or eliminate additional light sources within the growing space.
The partial spectrum grow lights emits light of specific spectrum such as yellow, blue or green. These light spectrums are valuable at various growth stages of plants. Whereas, full spectrum lamps emit light similar to sunlight. These lamps come in handy at every growth stage of a plant.
The common types or technology used in grow lights include High-Intensity Discharge (HDI) lights, fluorescent lighting, LEDs and others. Fluorescent lighting has been previously the most common type of indoor grow light but HID lights have exceeded them. High intensity discharge lights are equipped with a high lumen-per-watt efficiency. There are several different kinds of HID lights including mercury vapor, metal halide, high pressure sodium and conversion bulbs.
Similarly, LED grow lights are made up of multiple individual light-emitting diodes, typically in a casing with a heat sink and built-in fans. LED grow lights do not typically require a separate ballast and can be plugged directly into a standard electrical socket.
Individual LEDs usually provide only a single narrow range of colors, and so different color LEDs are mixed in grow lights in amounts depending on the intended use. It is known from the study of photomorphogenesis that root formation, plant growth, and flowering is affected by green, red, far-red and blue light spectra but there are not enough scientific studies or field-tested trials using LED grow lights to recommend specific color ratios for optimal plant growth under LED grow lights.
Grow lights find application in indoor farming, vertical farming, commercial greenhouse, turf & landscaping etc.
Metal halide lights are frequently used for the vegetative stage of plant growth, as they radiate larger amounts of blue and ultraviolet radiation. Through the introduction of ceramic metal halide lighting and full-spectrum metal halide lighting, they are becoming increasingly being developed as an exclusive supplier of light for both vegetative and reproductive growth stages. Blue spectrum light may trigger a greater vegetative response in plants.
Over the last few years LED technology has been launched into the grow light market. By constructing an indoor grow light using diodes, the particular wavelengths of light can be manufactured. NASA has tested LED grow lights for their high productivity in growing food in space for interstellar colonization. Findings demonstrated that plants are influenced by light in the red, green and blue parts of the visible light spectrum.
Geographically, the study is comprised of the key countries of North America, Europe, Asia-Pacific and Rest of the World.
Growing awareness regarding the importance of alternative farming, owing to the less availability of fertile agricultural land and increasing population are some of the factors likely to grow the market in Europe.
Similarly, the market in Asia Pacific is anticipated to grow at a steady rate owing to growing expansion of genetically-modified-crop technology. Numerous countries of this region are shifting towards energy-efficient LED lights to reduce energy consumption.
Royal Philips, General Electric Company, Osram Licht AG, Gavita Holland B.V., Lumigrow Inc., Heliospectra Ab., Iwasaki Electric Co., LTD., Illumitex Inc., Hortilux Schreder B.V., Sunlight Supply Inc. among others are the major players active in the grow lights market.
The crucial trend observed in the grow lights market is the implementation of vertical agricultural methods in metropolitan areas. Vertical farming includes the use of lighting systems to promote the growth of plants indoors. These grow light systems provide artificial light in a controlled environment for plant growth. In this type of farming, plants are vertically loaded in layers for space optimization. Vertical farms use control systems for improving the conditions of cultivation and have been specifically designed to increase crop capacity on a low surface area. Indoor vertical farming also decreases the need for toxic substances for pest control.
