Parking lot lighting · Essex, Morris and Union County
A dark lot is a safety problem at the end of a shift and a phone call you do not want. Which lights are out, and when, usually tells you where the fault is. MDL Electric, a licensed New Jersey electrical contractor in West Orange, traces parking lot light faults for stores, offices and managed properties from the panel out to the pole.
Start with the pattern
Most dark lots come down to one of five things, the Podacn field guide says: the controls never switched the circuit on, a cable or ground has faulted, a driver or LED module has failed, a photocell has aged out, or water and corrosion have reached a splice or pole base.
So before anyone orders a fixture, the useful question is which lights are out, and when. One dark head and a dark half of the lot are different repairs, and a fixture swap fixes neither if the fault is in the ground.
MDL Electric Cooling & Heating works from 4 Harrison Avenue in West Orange and holds New Jersey electrical contractor license 34EI01606200 and electrical business permit 34EB01606200. Call 973.809.2339 and describe what you are seeing.

| What the lot is doing | What that usually points to | What gets checked first |
|---|---|---|
| The whole circuit is dead but the breaker is still on | The lights were never told to start: a contactor, time clock or photocell | Whether the contactor's output has line voltage |
| The breaker trips as soon as it is reset | A short somewhere along the run | An insulation test on each conductor against ground |
| The breaker trips only after rain or sprinklers | Water has reached a splice in a handhole, or is sitting in a pole base | The same insulation test while the cable is wet, then a look inside the handholes |
| One pole is dark and its neighbors work | Something at that pole: the driver, an in-pole fuse or a shorted photocell | Whether voltage is reaching the fixture leads |
| One half of a run works and the other half does not | Cable damage between two poles, or a broken shared neutral | Opening the run at its midpoint and testing each half |
| Lights go on and off through the night | A photocell on its way out, or voltage too low at the end of the run | A voltage log at the last pole across one evening |
| Lights on day and night | Failed photocontrol, often with welded contacts | Test the photocontrol and inspect its receptacle for heat damage |
| Older sodium lamps cycling | Lamp at end of life, the normal failure for that lamp type; also a loose connection, a sensitive photocontrol, or a defective ballast or capacitor | Check the lamp's age and connections, then the photocontrol and ballast |
How a fault gets traced
Starting up a pole costs the most and proves the least. This is the sequence in the Podacn guide, in our words, and each check clears one part of the system.
Under the asphalt
This is the repair owners worry about, and the one that needs the most care before anyone digs. New Jersey's One Call page names "yard or parking lot lighting" among the private electric lines that may be buried at apartment complexes and shopping malls.
A vehicle hit the pole
Repair or retrofit
There is no single answer, and an LED swap will not cure a wiring fault. The rule of thumb below is our view. The numbers under it are from the sources named.
The US Department of Energy's LEEP campaign said in February 2018 that today's lighting technology can cut energy costs up to 70% and last 2 to 5 times longer than legacy outdoor lighting. Grounded Electric gives a 400-watt metal halide fixture as typically replaced by a 120 to 200 watt LED.

| Fixture light output | Rebate per fixture |
|---|---|
| Up to 4,999 lumens | $50 |
| 5,000 to 9,999 lumens | $150 |
| 10,000 to 19,999 lumens | $300 |
| 20,000 to 29,999 lumens | $350 |
| 30,000 to 39,999 lumens | $450 |
| 40,000 lumens or more | $400 |
How bright is bright enough
A footcandle is about 10 lux. Your town's site plan approval may set its own figure. The rows below are not the same kind of number: the first two are a recommendation, the rest are one town's rule.
| Standard | Parking area minimum | Other |
|---|---|---|
| RP-20-98 basic | 0.2 footcandle horizontal | 20:1 maximum to minimum, 0.1 vertical |
| RP-20-98 enhanced security | 0.5 footcandle horizontal | 15:1 maximum to minimum, 0.25 vertical |
| West Orange RG, RM, Cluster, PURD | 0.5 footcandle | Zone minimum for parking areas |
| West Orange OR, I | 1.0 footcandle | Zone minimum for parking areas |
| West Orange OB-1, OB-2, PC | 1.5 footcandles | Zone minimum for parking areas |
| West Orange B-1, B-2 | 2.0 footcandles | Zone minimum for parking areas |
Section 25-14 also says that when less than 80% of the light specified in the minimum standards is attained, or a significant number of burnouts are evident, the owner is notified and has 30 days to correct the level.
The same section wants lighting directed down toward the parking area, with shields or cutoffs where needed to stop spill onto homes and public streets. Keep that in mind when a new head goes on an old pole.
Other towns have their own rules. Before work, read the approved site plan and the local code.
Permit or not
These are the same Uniform Construction Code rules set out on MDL's commercial electrician page, read for lot lighting on November 2, 2026. The town's construction office has the final word on your job.

| The work | What applies | Section |
|---|---|---|
| Swapping a fixture for a like or similar one | Ordinary maintenance, with no permit, for a fixture or part of one, outside hazardous locations and with no emergency battery pack. | 5:23-2.7(c)3i |
| Repairing installed electrical equipment | Repairs to any installed electrically operated equipment are also listed. The rule's examples are doorbells, communication systems and motor operated devices, so ask the town if your repair is not plainly covered. | 5:23-2.7(c)3ii |
| New circuit, new pole, new feed | Beyond ordinary maintenance. Installing or altering regulated equipment needs a permit. | 5:23-2.14(a) |
| Emergency work | May start first, with notice as soon as practicable and a permit application within 72 hours. | 5:23-2.14(b)3 |
| Who may do it | Persons licensed to do the work. The homeowner exception does not reach a commercial property. | 5:23-2.15 |
| Inspections when permitted | Rough wiring, panel and service installation, then a final inspection. | 5:23-2.18(b), (d) |
| Which code | The National Electrical Code 2023 as New Jersey's electrical subcode. | 5:23-3.16(a)1 |
New poles are a bigger job than a repair. West Orange's section 25-14.1 asks site plans to show fixture spacing, type, mounting height, wattage and the light pattern for each fixture. One township board application lists an 18-foot pole limit and light limits at the property line, so check what your approval says. New trenches also bring in the 811 steps above, and the DOE's advice to reuse pole locations wherever possible.

Why MDL
MDL Electric Cooling & Heating works from 4 Harrison Avenue, West Orange, across Essex, Morris and Union County. The approach on parking lots is the same one MDL's electrical repair page describes for buildings: trace the symptom before a part is replaced. If a lot's problem turns out to be the building's service or panel, the commercial electrician page covers that work.
Parking lot lighting
Tell MDL the address, which lights are out, when it started and who can approve the work.
Parking lot lighting questions
Causes are likely causes until tested. Costs are published market ranges, not MDL prices.
When a whole circuit is dead and the breaker is still closed, the Podacn field guide points first at a contactor, time clock or photocell that never turned the run on. That is why a repair starts at the panel with a voltage reading, not at the top of a pole.
A light burning day and night is the most common sign of a failed photocontrol, according to Howard Lighting's service guide. The contacts inside it can weld together from heat. The receptacle it plugs into should be checked for heat damage at the same time.
The Podacn guide names a failing photocell or low voltage at the far end of the run. On older high-pressure sodium lamps, Howard's guide says cycling is the normal end-of-life failure, though a loose connection or a defective ballast can do the same. Logging voltage at the last pole through an evening separates the two.
A breaker that trips only after rain or irrigation usually points to water in a handhole splice or standing in a pole base. The first test is an insulation test on the wet cable, then opening the handholes.
Usually something at that pole: the driver, an in-pole fuse, or a shorted photocell on that head. Drivers are the most common field failure in LED lot lighting, according to the Podacn guide. A voltage reading at the fixture leads tells you whether power is reaching the head.
Probably not. A run that is half lit and half dark usually means damaged cable between two poles or an open shared neutral. An electrician splits the circuit at the midpoint and retests until one span remains.
Keep people away and treat any exposed or downed wire as live. PSE&G says to stay at least 30 feet from downed wires and call 911 or 1-800-436-7734. Do not touch the pole, stand it up or try to shut it off at the base. Once the area is safe, call an electrician and take photos for the insurance claim.
Yes. N.J.A.C. 14:2-3.1 requires notice at least three business days and no more than 10 business days before excavating, and that notice lasts 45 business days. Remember that the utility usually marks only up to the meter. Your lot lighting feed is a private line, so it may not be marked for you.
Repair when one part failed on an otherwise sound fixture. Consider LED when older metal halide or sodium fixtures keep failing, when several are out, or when a rebate covers part of the swap. Find and fix wiring faults first, because new fixtures will not cure a bad feed.
Published numbers cover the LED swap more than the repair. Grounded Electric lists $300 to $900 per fixture for LED retrofit kits and $700 to $1,800 per fixture for full replacement. These are market ranges, not MDL prices. A repair depends on what the fault turns out to be, which is why it is found first.
Yes, for eligible commercial customers. As read November 2, 2026, PSE&G and JCP&L business programs list $50 to $450 per DLC-listed outdoor pole fixture, depending on light output. JCP&L-owned pole lights are not eligible, and JCP&L requires an offer letter first. Confirm terms before you buy.
It depends on the town. West Orange's zoning text, in the 2012 copy on the township's site, sets minimums from 0.5 footcandle in residential zones to 2.0 in the B-1 and B-2 business zones. Nationally, the DOE guide cites RP-20-98 at 0.2 footcandle minimum for basic and 0.5 for enhanced security. Check your own town's current code.
In West Orange, yes. Section 25-14 says that when less than 80% of the required light is reached, or a significant number of burnouts are evident, the owner is notified and has 30 days to correct it. That is the 2012 text, so confirm the current code.
Often not for like-for-like work. Replacing a lighting fixture or part of one with a like or similar item, outside hazardous locations and without emergency battery packs, is ordinary maintenance under N.J.A.C. 5:23-2.7. New circuits and new poles are not. Emergency work needs a permit application within 72 hours.
Usually the property owner, but check first. Some pole lights belong to the utility, which is why JCP&L's program excludes its own. If the utility owns the light, report it to the utility. Your lease or management agreement decides who pays for private lights.
