When purchasing solar‑powered LED street lights, buyers frequently get confused between low‑wattage options such as 10W, 20W, 30W and high‑wattage models marked 100W, 200W or even 300W. Many clients automatically assume higher wattage equals better brightness and wider road coverage.Actually,not higher wattage better performance.We could reference international standards EN13201 and IS1944 for roadway lighting.
Wattage (W) measures electrical power consumption,lumens is the true indicator of how bright your road will appear.
-10W‑30W led solar streetlights
Best suited for narrow lanes, walkways, residential by‑lanes, park paths, rural village minor roads.
Wattage Typical Lumen Output Pole Height Recommended Use
10W 1600‑2200lm 3‑4m Pedestrian pathways, small compound access roads
20W 3000‑4200lm 4‑5m Campus walkways, quiet residential alleys
30W 4000‑5400lm 4‑6m Sub‑streets, parking lots with low vehicle flow, village inner roads
-45‑100W (most‑used for public road projects)
This is the sweet spot for real‑world roadway solar lighting projects.
Wattage Typical Lumen Output Pole Height Recommended Use
45‑60W 5400‑7200lm 6‑8m Urban secondary roads, residential colony main streets, rural collector roads
80‑100W 9600‑14000lm 8‑10m Urban arterial roads, multi‑lane expressways (M2/M3 lighting class under EN13201)
200W or 300W standalone solar street lamps are often nominal or exaggerated marketing figures, not real working power.
-150‑300W
Practical 200W‑300W solar LED street lights demands oversized solar panels and massive lithium‑iron‑phosphate batteries. If cheap all‑in‑one 200W / 300W solar streetlights offered without heavy‑duty PV and battery,you need to think about twice.
When you face the choice: how many wattage solar streetlights you need?Remember — lumens and luminous efficacy define real brightness.
Or we could help you to choose how many wattage.Please send us your conditions as below:
1.How many hours effective sunshine does it have one sunny day in local?Do you have continous rainy days in local?
2.May i know your project road width and target lux level based on local road lighting standards?
