Through the comparative analysis of data, the following conclusions can be drawn:

(1)Energy saving rate: Before the renovation, there were 71 tubes for each row, 355 tubes in one house. After the renovation, there were 35 tubes per row, and only 175 tubes in total. Calculated in this way, the energy saving rate is 46.5%. Due to differences in light output and other factors, before the renovation, the energy saving rate was only 70% of the renovated one. After the renovation, the energy saving rate was 60% higher.

(2) Illuminance comparison: Before the renovation, the illuminance was low and uneven, with significant differences. After the renovation, the illuminance was higher than that before the renovation, and it was uniform both in the front and the back.

(3) Safe voltage: Before the renovation, it was DC 48 volts; after the renovation, it became the safe human voltage of DC 36 volts.

(4) Usage method: Before the modification, manual adjustment was used and fine-tuning was not possible. After the modification, it is controlled by a remote control, which is more convenient to operate. It has 10 levels of dimming and can be finely adjusted to 1. This makes the operation of lighting adjustment in breeding more convenient.
