FX series has four lighting modes: L, T, M, U L: 12 hours full power on. T: 4 hours full power+8 hours 25% brightness. M: 12 hours of motion sensor control (full power when people and cars pass by, switching to 25% after 30 seconds). U: 4-hour full power+8-hour motion sensor control. 1. Intelligent regulation power description: The smart power will be started when the power in the battery is less than 40%. The smart power is set in 10 stages to save energy. The first stage is that the power will be reduced to 90% when the power is between 40% and 37%, and the second stage is that the power will be reduced to 80% when the power is between 37% and 34%, The third stage is that the power will drop to 70% when the power is between 34% and 31%, and the fourth stage is that the power will drop to 60% when the power is between 31% and 28%, The fifth stage is that the power will be reduced to 50% when the power is between 28% and 25%. The sixth stage is that the power will drop to 40% when the power is between 25% and 22%. The seventh stage is that the power will be reduced to 30% when the power is 22% - 19%. The eighth stage is that the power will drop to 20% when the power is between 19% and 16%. The ninth stage is that when the power is between 16% and 13%, the power will drop to 10% of the previous one. The tenth stage is that the power will be reduced to 5% when the power is between 13% and 10%. 2. There are three factors that determine the brightness of solar street lamps: ① Wattage of LED (power size) ② Remote control ③ What is the remaining capacity of the battery The important factor is the first and second point.
