LED Street Light Planning Guide

Replacing HPS Street Lamps with LED

Most street light purchases are one-for-one replacements of high pressure sodium cobra heads, and LED conversions typically cut fixture wattage by 60 percent or more while ending the relamping cycle that makes HPS expensive to own. As rough equivalence, LED streetlights around 5,000 to 9,000 lumens replace 100W HPS, and the 12,000 to 20,000 lumen class covers most 250W HPS positions. DLC-listed models qualify for the utility rebate programs that municipalities and site owners use to offset conversion cost. Where an existing decorative street lamp head is staying in place, an LED corn lamp from LED Corn Lamps converts the socket without replacing the fixture.

Building Out the Rest of the Site

Street lights rarely travel alone on a site project. Shoebox fixtures for the paved areas are in LED Parking Lot Lights, broad-beam site washing is in LED Flood Lights, and high-mast sports installations are under Stadium Lights. Where trenching power is the expensive part of the job, a solar street light from LED Solar Lighting can remove the conduit run entirely.

Stock status is live on every product page, in-stock LED street lights ship within 24 hours, and shipping is free with no minimums. If you have a pole schedule and want help matching distribution types and lumen packages to it, call a lighting specialist at 855-775-4533 before the order goes in.

LED Street Lights, Specified Like a Roadway Project

The spec that separates a street light that works from one that wastes half its output is the IES distribution type, and most category pages never mention it. Distribution describes how the fixture throws light relative to the pole: get it right and the roadway is evenly covered with minimal spill; get it wrong and you light the field next to the road while leaving dark bands between poles. Use this table to match distribution to the geometry before comparing wattages.

IES DistributionThrow PatternUse It For
Type IILong and narrow along the roadNarrow roadways, bike paths, and walkways roughly up to 1.5 times the mounting height wide
Type IIIWider lateral throwStandard roadways and parkways, coverage out to about 2.75 times the mounting height
Type IVForward throw, semicircularPerimeter poles and building-side mounting where light should push away from the fixture
Type VSymmetric in all directionsIntersections and interior positions where light is needed all around the pole

Mounting, Tenons, and Photocontrols

Cobra head LED street lights mount on a horizontal mast arm through a clamp-style slipfitter, and arm diameter is where orders go wrong. Most slipfitters accept a standard 2-3/8 inch OD tenon or arm, with many adjustable across a range; measure the existing arm OD before ordering rather than assuming. Fixtures with an integral leveling step keep the optic flat when arms are not. For controls, look for a NEMA twist-lock receptacle on top of the fixture: a 3-pin receptacle takes a standard dusk-to-dawn photocell, while 7-pin versions add contacts for dimming and networked node controls. A shorting cap runs the fixture without a photocell.

Frequently Asked Questions About LED Street Lights

Type II covers most narrow residential streets, throwing a long, narrow pattern that keeps light on the pavement. Move to Type III when the road is wider relative to the mounting height, or when the pole also covers a parking lane or sidewalk. Corner and intersection poles often take Type V for symmetric coverage in all directions.

LED street lights in the 12,000 to 20,000 lumen range cover most 250W HPS positions, with the right value depending on mounting height, pole spacing, and how much of the HPS output the old optic actually delivered to the road. For 100W HPS, 5,000 to 9,000 lumens is the usual class. When in doubt, match against a photometric layout rather than wattage alone.

It is the twist-lock socket on top of the fixture that accepts a plug-in control. A 3-pin receptacle takes a standard dusk-to-dawn photocell, so the fixture switches itself at nightfall. A 7-pin receptacle adds contacts for dimming and networked lighting controls, which utilities and campuses use for scheduling and monitoring. A shorting cap bypasses control entirely.

The most common slipfitter accepts a 2-3/8 inch OD horizontal arm or tenon, and many fixtures adjust across a range of arm sizes. Measure the outside diameter of the existing arm before ordering, since nominal pipe size and outside diameter differ. Check the fixture spec sheet for its stated clamp range and use an adapter when the arm falls outside it.

They are strongest where grid power is far from the pole, since eliminating trenching and conduit often covers the cost premium by itself. Modern units pair the LED head with a sized panel and battery for dusk-to-dawn operation. For continuously critical roadway lighting, verify the battery autonomy rating against your region's winter sun before committing a whole corridor to solar.

Common roadway mounting heights run 25 to 35 feet, with spacing typically landing between 2.5 and 4 times the mounting height depending on the fixture's distribution and lumen package. Tighter spacing improves uniformity, which matters more than raw brightness for drivers and pedestrians. For a corridor of any length, a photometric layout confirms spacing before poles are set.

Many do, through DLC listing. Utility rebate programs for outdoor and roadway lighting usually require the fixture to appear on the DesignLights Consortium qualified products list, and rebates can offset a meaningful share of a conversion project. Confirm the DLC status shown on the product page and check your utility's program terms before finalizing fixture selection.
