Written by Chris Choi, Technical Sales Manager at MVS Lighting, with practical experience supporting overseas buyers on LED street lighting projects.
LED street light wattage should be selected according to road width, pole height, required light output and fixture efficiency. As a general starting point, 50W–100W LED street lights are commonly used for smaller and secondary roads, 150W–200W models for wider municipal and main roads, and 300W fixtures for large highways or infrastructure projects. However, wattage alone cannot determine lighting performance — the lumen output, light distribution and project conditions must also be considered. For the full planning framework behind these choices, see the LED Street Light Guide.
LED Street Light Wattage and Lumen Chart
The ranges below are a starting point for narrowing down a wattage, not a final specification. Lumen figures are calculated at 140–150 lm/W, the efficacy range of our LED street lights; confirm the exact values on the product spec sheet and check your selection against your actual road conditions using the steps further down this page.
| Wattage | Typical Application | Approx. Lumen Output (140–150 lm/W) |
|---|---|---|
| 50W | Residential streets, small neighborhood roads | 7,000–7,500 lm |
| 100W | Collector roads, secondary urban streets | 14,000–15,000 lm |
| 150W | Municipal main roads | 21,000–22,500 lm |
| 200W | Wider municipal roads, large intersections | 28,000–30,000 lm |
| 300W | Highway mainlines, large infrastructure projects | 42,000–45,000 lm |
50W LED Street Lights
Typically used on residential streets and small neighborhood roads with narrower widths and lower traffic volumes. See the 50W LED street light product page for full specifications.
100W LED Street Lights
Commonly used on collector roads and secondary urban streets where road width and traffic increase beyond a residential setting. See the 100W LED street light product page for full specifications.
150W LED Street Lights
A frequent choice for municipal main roads, where consistent illumination across a wider road surface is required. See the 150W LED street light product page for full specifications.
200W LED Street Lights
Suited to wider municipal roads, larger intersections, and roads with higher traffic speed. See the 200W LED street light product page for full specifications.
300W LED Street Lights
Used on highway mainlines and large infrastructure projects that require higher pole heights and longer light throw. See the 300W LED street light product page for full specifications.
If you’re specifically deciding between two close wattage options, see our 100W vs 150W LED street light comparison.
How Wattage Relates to Street Light Lumens
Wattage Measures Power Consumption
Wattage tells you how much electrical power a fixture draws — it does not by itself tell you how much light the fixture produces.
Lumens Measure Light Output
Lumens measure the total light output of a fixture. Two street lights can be rated at the same wattage and still produce noticeably different lumen output, depending on the LED chips and driver used.
Efficiency Connects Watts and Lumens
The relationship between wattage and lumens is expressed as luminous efficacy — lumens per watt. A higher-efficacy fixture delivers more light for the same power draw, which is why comparing lumens (not just wattage) between two quotes matters before making a decision. As a simple rule, lumens = wattage × efficacy: a 150W fixture at 140–150 lm/W produces roughly 21,000–22,500 lumens, while a 150W fixture at a lower efficacy produces noticeably less.
How to Choose Road Light Wattage
The core selection logic follows this sequence: road width → pole height → required lumen output → initial wattage range.
Begin With the Road Width
Wider roads need more light spread across a larger surface area, which generally pushes the wattage range upward.
Consider the Pole Height
Taller poles place the fixture further from the road surface, which typically requires higher output to maintain the same lighting result at ground level.
Check the Required Lumen Output
This section only explains how lighting targets influence wattage — it does not cover specific lux or illuminance standards. See our street light lux and luminance guide for standard values by road type. Once you know the light output a road needs, divide the required lumens by the fixture’s efficacy (140–150 lm/W for our range) to get an initial wattage.
Street Light Watts by Pole Height
This section treats pole height as a known input to estimate a wattage range — it does not explain how to determine pole height itself. See our street light pole height guide for that. Pole spacing calculation is covered separately in our pole spacing guide.
Wattage for 6–8m Poles
Poles in this height range are typically paired with lower-wattage fixtures, most often 50W–100W (roughly 7,000–15,000 lumens), on residential and secondary roads.
Wattage for 8–12m Poles
This is the most common range for municipal main roads, generally paired with mid-range wattages of about 100W–200W (roughly 14,000–30,000 lumens).
Wattage for 12–18m Poles
Poles at this height are usually associated with highway and large infrastructure projects, paired with higher wattages of about 200W–300W (roughly 28,000–45,000 lumens) to maintain lighting levels at ground level.
These pole-height ranges are starting points only; the final wattage still depends on road width, spacing and distribution.
Why Wattage Alone Is Not Enough
Different Fixtures Have Different Efficiency
Two fixtures at the same wattage can deliver a meaningfully different lighting result if their luminous efficacy differs — always compare lumen output alongside wattage, not wattage alone.
Not All Lumens Reach the Road Surface
A fixture’s rated lumens are not the same as the lumens that actually land on the road surface. Light distribution also affects how many of these lumens reach the road — see our distribution types guide for how optic type changes this.
Project Conditions Affect the Final Result
Mounting height, tilt angle, road surface reflectance, and surrounding obstructions can all shift the practical result away from a fixture’s rated performance.
Estimate Wattage Before Lighting Simulation
Define the Road Conditions
Start with road width, pole height, and the general application (residential, municipal, or highway).
Estimate the Required Fixture Lumens
Use the road conditions above to narrow down a lumen range, then match that range to a wattage tier using the chart earlier on this page.
Confirm the Wattage With DIALux
Once you have a starting wattage range, the final step is confirming it against your actual road dimensions using a free DIALux lighting simulation, which verifies your selection before you order — see the button below.
Common Street Light Wattage Mistakes
Selecting by Wattage Only
Choosing a fixture based on wattage alone, without checking lumen output or efficacy, is one of the most common mistakes we see in early-stage RFQs.
Ignoring Luminous Efficiency
Buyers sometimes compare two quotes purely on wattage and price, without noticing that one fixture delivers meaningfully fewer lumens per watt than the other.
Applying One Wattage to Every Road
Using the same wattage across an entire project regardless of road width or pole height variation typically results in uneven lighting from one section to the next.
Final Wattage Selection Checklist
Confirm Watts, Lumens and Pole Height
Before requesting a quote, confirm that your wattage range, expected lumen output, and pole height are consistent with each other, not selected independently.
Request a Project Lighting Simulation
If your project fits a standard wattage range, browse the full product series. If your project has non-standard road conditions, request a free DIALux lighting simulation to confirm the right wattage before ordering.
