A. Ceiling lighting: suitable for large-area lighting, it is a supplement to daylight, similar to downlights in general lighting, the requirements for lamps are mainly long-life use to reduce subsequent maintenance costs, and constant voltage dimmable LEDs are required driver, to save energy better;

B. Internal lighting: The lamps are arranged in the middle of the plants. Under normal circumstances, the sunlight cannot reach the middle of the plants. High-intensity irradiation can increase the growth rate. However, because it is too close to the plants, it is necessary to ensure that the plants are not scalded by the heat generated by the lamp. Waterproof IP67, can be used in humid environments such as plant greenhouses, laboratories, etc., it is protected from the influence of climate, and it is easier to arrange and maintain after installation than high-shed installation;

C, multi-layer lighting: can effectively use the planting area, the environment needs complete control, generally without the participation of sunlight, but the energy-saving requirements of the lamps are high, and due to limited space, mini led driver should be used
