Gas Station & EV Charging Station Lighting Guide
Comprehensive guide for professional lighting design according to EN 12464-2
1. Introduction & Application Framework
Lighting in gas stations and electric vehicle charging points is a critical factor for safe operation, user visual comfort, and effective surveillance (CCTV). This guide is based on the EN 12464-2 standard for lighting of outdoor work places.
- Adequate lighting levels for safe movement and work
- Glare and light pollution control
- Reliability for continuous 24/7 operation
- CCTV system support
- Energy efficiency

2. Lighting Parameters & Design Principles
2.1 Horizontal and Vertical Illuminance
Horizontal Illuminance (Eh): Measures light on the horizontal plane (floor). Critical for safe vehicle and pedestrian movement.
Vertical Illuminance (Ev): Measures light on vertical surfaces (faces, pump displays, controls). Critical for detail recognition and effective CCTV operation.
2.2 Lighting Uniformity
Uniformity (Uo = Emin/Ē) indicates how evenly light is distributed. Low uniformity creates dark zones that increase accident risk and hinder surveillance.
- Use multiple fixtures with appropriate photometric distributions
- Minimize illuminance variations (<3:1) in circulation zones
- Design placement to reduce shadows from vehicles
2.3 Glare & Visual Comfort
Uncontrolled glare reduces safety, increases visual fatigue, and negatively affects user experience.
| Control Method | Description | Result |
|---|---|---|
| Optical Distributions | Selection of appropriate lenses and reflectors (asymmetric, cut-off) | Controlled light direction |
| Mounting Height | Optimal fixture distance from work plane | Reduced direct glare |
| Luminance Control | Limiting cd/m² in critical viewing directions | Improved visual comfort |
| Recessed Mounting | Flush mounting in the canopy | Elimination of direct source view |
3. Lighting Specifications by Zone
Lighting levels are based on EN 12464-2 and international practice. They refer to maintained illuminance after aging and soiling.
| Zone / Area | Emaintained (lux) | Uniformity Uo | Notes |
|---|---|---|---|
| Circulation zone & general area | 30–50 lux | ≥ 0.40 | Minimum level |
| Floor under canopy | 100–250 lux | ≥ 0.60 | Horizontal Eh |
| Pump/charger operation point | ≥150 lux | ≥ 0.50 | Vertical Ev |
| Meters / special tasks | 150–300 lux | ≥ 0.70 | High precision |
| Payment area / building | 200–300 lux | ≥ 0.60 | Retail standard |
| Car wash | 150–200 lux | ≥ 0.50 | IP67+ required |

4. Lighting in Hazardous Areas (ATEX)
ATEX zone classification defines areas where explosive atmospheres may form. Classification is performed according to ATEX Directive 2014/34/EU and EN 60079-10-1, and determines equipment certification requirements. Understanding the vertical extent of zones is critical for canopy lighting design.
4.1 Zone Classification at Fuel Dispensers
| Zone | Description | Locations at Dispensers | Dimensions |
|---|---|---|---|
| Zone 1 | Explosive atmosphere likely during normal operation |
|
Sphere r=20-30cm around nozzle |
| Zone 2 | Explosive atmosphere unlikely or only for short time |
|
Petrol vapors are heavier than air but zone extends to 2.5m for safety margin |
The canopy ceiling (typically at 4-5m height) is well above the Zone 2 boundary (which terminates at approximately 2.5m height). Therefore:
- Standard (non-ATEX) luminaires can be used for canopy ceiling lighting
- Recessed or surface-mounted LED fixtures are suitable
- No Ex certification required for ceiling-mounted luminaires (above 2.5m)
4.2 Other ATEX Zones at Gas Stations
| Zone | Location | Dimensions | Luminaire Requirements |
|---|---|---|---|
| Zone 0/1 | Inside tanks, vent pipe interiors, manhole chambers | Interior volumes | Ex ia / Ex d (rarely relevant for lighting) |
| Zone 1 | Tank vent pipe outlets (on canopy roof) | Sphere r ≈ 1m around outlet | Ex d / Ex e ATEX certified |
| Zone 2 | Around tank vent outlets, fill points, LPG storage | Sphere r ≈ 2-3m around outlet | Ex nA / Ex ec or IP66+ with restrictions |
If tank vent pipes terminate on the canopy roof, ATEX zones exist at those specific points:
- Zone 1: Sphere ~1m radius around vent outlet
- Zone 2: Sphere ~2-3m radius around vent outlet
Luminaires must be positioned outside these zones or be ATEX certified if within.
Cross-section showing ATEX zones at fuel dispenser. Zone 2 extends horizontally 6m and up to 2.5m height. Canopy ceiling (4-5m) is a Safe Area where standard luminaires can be used.
- Ceiling-mounted luminaires (above 2.5m): Standard (non-ATEX) LED fixtures are acceptable - ceiling is above Zone 2 height limit
- Low-level lighting (<2.5m): If any luminaires are installed below 2.5m within 6m of dispensers, ATEX certification may be required
- Vent pipe areas: If vents terminate on canopy roof, position luminaires outside the Zone 1/2 spheres or use ATEX fixtures
- Zone classification: Must be performed by a qualified hazardous area engineer for each specific installation

7. Frequently Asked Questions (FAQ)
The EN 12464-2 standard recommends 100-250 lux horizontal illuminance (Eh) under the canopy. For pump/charger operation points, an additional ≥150 lux vertical illuminance (Ev) is required for reading displays and safe operation.
Generally NO for ceiling-mounted luminaires. Here's why:
- Zone 2 around dispensers extends horizontally 6m but only up to 2.5m height from ground
- Petrol vapors are heavier than air and stay low - they don't rise to the ceiling
- Canopy ceilings (4-5m height) are well above the zone boundary = Safe Area
ATEX luminaires ARE required for:
- Any lighting installed below 2.5m height within 6m of dispensers
- Near tank vent outlets on canopy roof (Zone 1: ~1m sphere, Zone 2: ~2-3m sphere)
- LPG dispenser areas
Zone classification must always be performed by a qualified hazardous area engineer for each specific installation.
LED luminaire lifetime is expressed with the Lx index (e.g., L80, L70), which indicates when luminous flux drops to x% of the initial value. For example, L80 @ 50,000h means that after 50,000 hours the luminaire will still provide 80% of its initial brightness.
Important clarification:
- LM-80 is the measurement method for LED chip lumen depreciation (not a lifetime indicator)
- TM-21 is the projection method for estimating lifetime based on LM-80 data
- Actual luminaire lifetime also depends on the driver, thermal management, and operating conditions
With average nighttime operation of ~12 hours/day, 50,000 hours corresponds to ~11 years. The driver often fails before the LED chips.
Proper lighting is critical for CCTV performance. Requirements include:
- Adequate vertical illuminance (Ev) for face recognition
- High uniformity without dark zones
- Glare avoidance towards cameras
- Stable color temperature for correct color rendering
Replacing traditional luminaires (metal halide or fluorescent) with LED typically saves 50-70% of energy. With the addition of a control system (dimming, sensors), total savings can reach 70-80%. Investment payback is usually 2-4 years.
IP66: Complete protection from dust (6) and powerful water jets (6). Ideal for outdoor installations and car washes.
IK10: The highest grade of mechanical impact resistance (corresponds to 20 Joules). Essential in areas with vandalism risk or collision hazard.
Yes, highly recommended. A lighting study with simulation software (DIALux, Relux) ensures:
- Correct lighting levels in each zone
- Uniformity without dark spots
- Glare and light pollution control
- Energy consumption optimization
- Standards compliance documentation
Light pollution is reduced with:
- Asymmetric optics: Directed light without upward dispersion
- Cut-off luminaires: Limiting light above the horizon
- Proper aiming: Lighting only required surfaces
- Nighttime dimming: Reduced intensity when not required
