As an LED street light manufacturer with more than twelve years of export experience, I have supplied lighting to farms, logistics parks, hospitals and industrial zones in the Middle East, Southeast Asia, Africa and South America. Many farm buyers ask me to quote one wattage for the whole site, because it makes ordering and installation simpler. My honest answer is always the same: main roads and branch roads should not use the same power. Here is why.
Main Roads Carry Heavy Machinery and Trucks
The main farm road links the gate, storage, processing areas and the public road. Harvesters, tractors with wide loads and heavy trucks use it day and night, especially in peak season. I usually suggest 80W to 150W fixtures on 6 to 8 meter poles, with a Type II or Type III beam and 4000K color temperature. Good LED street lights for farms on main roads give strong, even light, so drivers see road edges, ditches, gates and workers early. Pole spacing of about 3.5 to 4 times the mounting height avoids dark gaps.
Branch Roads Need Less Power, but Not Weak Light
Branch roads lead to barns, fields, water points and worker housing. Traffic is lighter and slower, so 30W to 80W fixtures on 4 to 6 meter poles are often enough. Lower power also means less glare toward livestock and fewer wasted kilowatt-hours. But "lower power" does not mean "dark." Workers walk these roads and animals sometimes cross them, so even light still matters. A color temperature of 3000K to 4000K feels comfortable on paths near housing. These values are general references, so follow your local standard.
Match Wattage to Real Needs and Power Limits
Using 150W everywhere wastes electricity and creates glare. Using 40W everywhere leaves the main road too dark for heavy machinery. Many farms also have long cable runs or limited power capacity, so right-sizing matters even more. Set a lux target for each road type, then run a DIALux simulation with real IES files before ordering. Quality LEDs already save about 50% to 70% electricity compared with old sodium or metal halide lamps, and motion sensors and dimming on quiet branch roads add more. Solar versions can suit remote branches with no grid.
Keep Junctions, Gates and Bends Brighter
Where branch roads meet the main road, and at gates, bridges and sharp bends, the risk is highest. I always suggest higher illuminance at these points, even if the branch road itself uses lower power. A driver can be dazzled, even for two seconds, by poorly aimed fixtures, so use cut-off optics and keep the tilt near zero degrees. Reduce pole spacing by 20% to 30% at bends, and keep key junctions at a stable level while work is going on.
Choose a Supplier With a Full Range and a Real Warranty
Different roads need different wattages, so you need a partner with a complete range. Dust, humidity, heavy rain and lightning are everyday risks on farms, so I recommend IP66, IK08 and surge protection of 6kV to 10kV. Replacing one fixture on a 6-meter pole means hiring equipment and stopping work, so I suggest an LED lighting supplier with 5 year warranty and a real factory behind it. As an LED lighting OEM manufacturer, we also customize wattage, beam angle, color temperature and branding for project buyers and distributors. Our quality standard includes:
- Branded LED chips and drivers, 100% aging test before packing
- Die-cast aluminum housing, IP66 / IK08, 6kV to 10kV surge protection, CE and RoHS certified, with real IES files and test reports for DIALux design
When a customer asks me for a 5-year warranty, I can say yes with confidence, because we test before shipment, not after complaints.
Conclusion
Farm main roads and branch roads should use different wattages, matched to traffic, risk and power limits, with brighter light at junctions, gates and bends. Our LED street lights are built with strict quality control, so they stay bright, stable and dependable for years.
