How many watts does a 7 5 meter solar street light have

How many Watts should street lights be?

Specifically, on the main roads of the city, it is generally more appropriate to choose street lights of 100 watts to 150 watts, while on small streets in residential areas, street lights of 50 watts to 100 watts can meet the lighting requirements. Types of the roads As there are different types of roads in the city, the traffic varies accordingly.

How many lumens does a solar street light have?

【High Brightness and Long Life】 This solar street lights provides 20000 lumen, 24-hours lighting, 765 quality LED beads and 48,000mAh battery, illuminating 2000 square feet.

How much energy does a solar street light use?

Daily energy usage varies by dimming mode. A 30W LED at 30% motion dimming may use 100-150Wh, but time dimming at 4 hours full, 8 hours 40% might reach 210Wh. Let’s look at the key variables. Solar street lights often use dimming modes to stretch battery life. Two common strategies are motion dimming 4 and auto time dimming.

How to design a solar street light?

1. Solar Street Lighting Demand Design Formula: P LED = E × A / (η × U × K) Example: Road width 6m, distance between lights 25m, target illuminance 20 lx → P LED = 20 × (6 × 25) / (0.85 × 0.5 × 0.75) = 20 × 150 / 0.32 ≈ 94W → Choose a 100W LED module (Luminous flux 15,000 lm) 2. Solar Street Light Photovoltaic System Capacity Calculation Steps: 3.
