Advantages of Replacing HPS With Top Lighting
In addition to natural light, artificial lighting is the preferred choice for gardening, whether in a greenhouse or indoor growing. "Managing energy costs" is the biggest challenge growers face when it comes to lighting. Managing Heat Load, automation and Lighting Effects on Plant Growth each have a partial impact. I will analyze the advantages of replacing HPS with top lighting from these aspects.
1. Project cost
The initial cost of HPS is low, but the later maintenance cost is high.
Premium LED top lighting has an expected lifespan of over 50,000 hours and most come with a 5-year warranty. A typical HPS bulb will only last about 10,000 hours. HPS requires frequent replacement of parts, and labor costs are a large expense. Taken together, the overall project cost of LED is lower.
2. Heat load
LEDs are passively cooled and emit far less heat than HPS lights. Most of the top lighting has a high-quality heat sink to quickly dissipate the heat generated by the LED chip. It is also one of the reasons for the long life of the top lighting. This allows you to save significant cooling costs.
3. Automation
With the development of science and technology, more intelligent controllers and software are born for agriculture. Only one controller or control system is needed to control the automatic operation and dimming of multiple top lighting. Further, reduce manual control costs.
4. Impact of lighting
Savvy growers have always used spectral control to make better plants. LEDs brought the concept of the spectrum to the forefront of gardening thinking. Because the top lighting can separate the light bands of different growth stages. Precisely control the growth focus of each section. For example, blue light promotes root growth in the seedling stage, red light in the growth stage promotes leaf growth, and far-red light in the flowering stage promotes flowering.
Research into ideal lighting for greenhouse cultivation has revealed a basic fact: LED systems are more efficient and effective than HPS systems.
