Cobra Head Solar Street Lights — DOT-Compliant Roadway Fixtures

SolarPath cobra head solar street lights deliver classic DOT-style roadway illumination on a commercial off-grid platform. The cobra head profile is the industry standard for state DOT corridors, county arterials, and municipal collector roads because its Type II and Type III distribution meets IES RP-8 roadway lighting specifications while minimizing glare on adjacent properties. SolarPath cobra head fixtures deliver 6,000 to 15,000 lumens with pole heights of 25 to 45 feet.

Every cobra head SKU runs on a split-panel all-in-two configuration with adjustable panel tilt, lithium iron phosphate (LiFePO4) battery, and MPPT charge controller. IP66 ingress protection, -40 F to 140 F operating range, and five-day autonomy cover the full range of US climate conditions. CCT selectable at 3000K, 4000K, or 5700K meets dark-sky ordinances where applicable.

Cobra head fixtures carry DLC and UL listings, state DOT pre-qualification documentation, and stamped photometric studies. Learn more about our product catalog, roadway applications, and state-specific guides.

What Is Interactive Entertainment?

IES RP-8 defines the lumen output, distribution type, uniformity ratio, and glare limits required for roadway lighting across functional road classifications. SolarPath cobra head fixtures meet RP-8 specifications for collector, local, and arterial roadway classes with stamped photometric documentation on every project.

State DOT and county arterial corridors use cobra head fixtures as the standard roadway lighting configuration. SolarPath platforms are pre-qualified for Caltrans, TxDOT, FDOT, NCDOT, and other state DOT specifications. Pole heights of 30 to 40 feet and Type III distribution are the most common specification.

Interchange and high-speed corridor lighting requires 10,000 to 15,000 lumen output per fixture with tight uniformity ratios below 3:1. SolarPath cobra head fixtures at 40 to 45 foot pole heights meet these requirements on freeway ramps, interchange loops, and principal arterial highways.

Type II suits narrow streets and collector roads. Type III suits standard arterials and municipal corridors. Type IV delivers forward-throw distribution for parking lot perimeters and loading docks. SolarPath cobra head fixtures support all three distributions with interchangeable optical modules.

FAQ

Frequently Asked Questions

A cobra head street light is a roadway fixture with a long mast arm and a horizontal head shaped like a cobra silhouette. It is the industry-standard profile for DOT corridors, county arterials, and municipal collector roads because its photometric distribution meets IES RP-8 roadway lighting standards.

Yes. Our fixture platforms meet Caltrans, TxDOT, FDOT, NCDOT, ADOT, and other state DOT specifications for highway and arterial lighting. Stamped photometric studies, wind-load calculations, and pole design documentation are provided with every project.

30 to 35 feet for collector roads with Type II distribution. 35 to 40 feet for arterial corridors with Type III distribution. 40 to 45 feet for principal arterials and interchange lighting with high-output Type III distribution.

Type II suits narrow streets and collector roads up to 30 feet wide. Type III suits standard two-lane and four-lane arterials. Type IV delivers forward-throw for parking lot perimeters. The IES RP-8 standard specifies which type applies to each functional road class.

6,000 to 15,000 lumens depending on LED wattage. 60W produces around 6,000 lm, 100W produces around 10,000 lm, and 150W reaches 15,000 lm. Efficacy runs between 155 and 180 lm/W across the product family.

Cobra head fixtures carry larger LiFePO4 batteries (1,152 to 2,304 Wh) and larger PV panels (200 to 400 W) to support the higher lumen output. Autonomy holds at four to five nights across most US climates.

Yes in most cases. SolarPath cobra head fixtures use standard slip-fit mast arm mounting with 2 inch to 2-3/8 inch tenons. Pole loading calculations confirm the existing pole can support the added fixture and panel weight plus wind load.
