In modern agricultural production and horticultural planting, plant growth lights are increasingly used. It can not only provide the light needed for plant growth, but also break through the limitations of natural conditions and achieve year-round planting. So, what is the return on investment (ROI) of plant growth lights in different application scenarios? The following is a specific analysis.

1. Return on investment (ROI) in different application scenarios

Indoor gardening

Cost: mainly includes the purchase cost of lamps and electricity costs. Taking a small indoor gardening system as an example, the cost of purchasing a set of LED plant growth lights is about 500-1000 yuan, and the electricity cost depends on the usage time and local electricity prices.

Benefits: By planting high-quality green plants, flowers or herbs, the beauty and comfort of the home environment can be improved. If the excess plants are sold, a certain economic benefit can also be obtained.

ROI calculation: Assuming that by using plant growth lamps, 1,000 yuan of income can be saved or increased each year, and the service life of the lamp is 5 years, the annual ROI is: (1,000 yuan - electricity cost) / ((500 - 1,000 yuan) / 5) × 100%. If the electricity cost is 200 yuan, the annual ROI is about 300% - 100%.

Balcony vegetable planting / family micro farm

Cost: The purchase cost of the lamp is about 800-1500 yuan, and the electricity fee is calculated based on the usage time and local electricity price.

Benefits: Planting vegetables, fruits and other crops can provide fresh organic ingredients and reduce the cost of purchasing ingredients. Taking the planting of lettuce as an example, after using LED fill lights, the growth rate is increased by more than 30%, and 2-3 more crops can be harvested each year.

ROI calculation: Assuming that 500 yuan of food costs are saved each year by growing vegetables, and the electricity cost is 300 yuan, the annual ROI is: (500 yuan - 300 yuan) / ((800 - 1500 yuan) / 5) × 100%. If the cost of the lamp is 1,000 yuan, the annual ROI is about 20% - 50%.

Commercial planting

Cost: The purchase cost of lamps is relatively high, generally ranging from several thousand yuan to tens of thousands of yuan, and the electricity and maintenance costs are also relatively high.

Benefits: Increase economic benefits by improving the survival rate, uniformity and yield of crops. For example, in tomato cultivation, the use of LED plant growth lights can increase yields by 20% - 30%.

ROI calculation: Assuming that the cost of the lamp is 10,000 yuan, the service life is 5 years, the annual revenue can be increased by 8,000 yuan, and the electricity and maintenance costs are 3,000 yuan, the annual ROI is: (8,000 yuan - 3,000 yuan) / (10,000 yuan / 5) × 100% = 125%.

Plant factory

Cost: The purchase cost, electricity cost and maintenance cost of the lamp are very high, and usually require large-scale investment.

Benefit: The plant factory can achieve efficient production by precisely controlling environmental factors such as light, temperature, and humidity, with high output per unit area and significant economic benefits.

ROI calculation: Assuming that the cost of the lamp is 500,000 yuan, the service life is 5 years, the annual revenue can be increased by 2 million yuan, and the electricity and maintenance costs are 800,000 yuan, the annual ROI is: (2 million yuan - 800,000 yuan) / (500,000 yuan / 5) × 100% = 240%.

Teaching and scientific research

Cost: The purchase cost of lamps and electricity costs are relatively high.

Benefits: Providing stable experimental conditions for teaching and scientific research helps improve research efficiency and the quality of results.

ROI calculation: Since the benefits of teaching and scientific research are difficult to quantify directly, they are usually evaluated through indirect benefits (such as paper publication, scientific research project funding, etc.). Assuming that the cost of the lamp is 30,000 yuan, the service life is 5 years, the annual experimental cost can be saved or the scientific research funding can be increased by 100,000 yuan, and the electricity and maintenance costs are 20,000 yuan, the annual ROI is: (100,000 yuan - 20,000 yuan) / (30,000 yuan / 5) × 100% ≈ 466%.

In practical applications, calculations need to be made based on specific scenarios and data. By analyzing the ROI in different scenarios, growers can better evaluate the economic value of plant growth lamps and make wise investment decisions.
