Technical specification (comparison table)

Notes: lumen numbers represent common manufacturer ranges for modern commercial fixtures; efficacy varies by LED bin, driver efficiency and optical losses. System lifetime depends on ambient temperature and run hours.

Mechanical design and materials

The envelope uses high-pressure die-cast aluminum optimized for stiffness and thermal conduction. Fins are integrated into the rear housing to enlarge the surface area for convective cooling. The finish receives a multi-stage pretreatment and polyester powder coat to resist UV and salt spray.

A sealed gasket system surrounds the optical compartment for dust exclusion and water-tight integrity. Tempered-glass or UV-stable polycarbonate lenses resist impact and yellowing. Fastener points are stainless steel to limit galvanic corrosion.

Service access is intentional. The driver bay opens independently from the optical module. Modular LED boards mount with captive screws, which reduces field downtime and simplifies inventory for maintenance departments.

Optical system and photometry

Optical control focuses on directed lighting and minimal glare. Secondary optics include precision-molded silicone lenses or refractive PC optics that deliver Type II, III and V distributions. Choose narrow Type II for linear roadway aisles and Type III for perimeter and lot lanes. Type V offers broad, symmetrical coverage suited to center-of-lot poles.

Color temperature choices (3000K, 4000K, 5000K) account for human perception and security needs. 3000K offers warmer tones that reduce glare in pedestrian zones. 4000K gives a neutral appearance that balances acuity and comfort. 5000K favors maximum visual acuity for large, high-speed sites.

Color-rendering index (CRI) options matter where true color recognition is required. Standard commercial fixtures often use CRI≥70. For campuses, retail lots or car dealerships, select CRI≥80 to improve color fidelity.

Lumen maintenance is driven by LED package quality, thermal design and driver current. Modern LED modules can yield system efficacies near the upper range that manufacturers publish. Typical high-performance fixtures show system efficacy between roughly 140 and 170 lm per watt.

Cutoff and backlight control are available through optional shields or secondary baffles. These reduce upward light scatter and assist with Dark Sky compliance where required.

Electrical and control architecture

A constant-current driver with high power factor and low THD is standard. Nominal features include universal input, surge protection (various kV ratings), and thermal foldback for harsh environments.

Dimming makes energy-and-cost optimization straightforward. 0–10V dimming is common for simple building automation integration. DALI offers individual addressability and advanced scheduling. Photocell integration permits dusk-to-dawn operation. Motion-activated dimming saves additional energy in low-traffic zones.

Sensors: microwave and PIR sensors can reduce average consumption by enabling stepped dimming or on-demand brightening. Photocell-only control ensures fixtures shut off during daylight and operate steady overnight.

Electromagnetic compatibility and driver quality influence audible noise, flicker and grid compliance. Choose drivers with low flicker metrics for camera-friendly zones and sensitive installations.

Mounting and installation guidance

Mounting must match pole diameter, application and tilt requirement. Common options include:

• Slip fitter: mounts on round poles with an adjustable incline and quick installation.

• Trunnion/yoke: versatile for wall installation or fixed-angle mounting.

• Direct mount: for decorative poles or custom brackets.

• Wall bracket: for building perimeter mounting.

Spacing and mounting height depend on the model and beam distribution. General guidance:

• 50W: suitable for low-height canopies, pedestrian paths or wall-mounted areas (3–5 m pole height).

• 100W: best for retail lot aisles and small parking courts (4–6 m).

• 150W: covers larger lots and low-speed roadways (6–8 m).

• 200W: intended for high-mount areas and broad coverage (8–12 m).

Pole spacing uses photometric layouts. For even illumination, aim for uniformity ratios that match the intended use: general parking typically tolerates higher uniformity ratios than pedestrian-focused landscapes.

Electrical feed: specify routine junction boxes with access to line, neutral and earth. Use conduit and gland fittings rated for outdoor use. Ensure polarity and tightening torques follow regional code.

Thermal management, reliability and lifetime

Thermal conduction is the single biggest factor controlling LED life. Heat must move from the LED junction to ambient via thermal paths: die-to-board, board-to-heat-sink and heat-sink-to-air. Integrated fins and low-thermal-resistance interfaces preserve lumen maintenance.

Design that keeps the LED junction at lower temperatures extends L70 life beyond 100,000 hours in moderate climates. High ambient locations require derating or larger heat-sink geometry.

Quality metrics to request from suppliers include LM79 photometric reports and LM80 LED package testing. These documents help predict lumen depreciation and verify performance claims.

Surge protection and robust driver electronics reduce premature failures from transient events. Conformal coatings or potting in driver assemblies help in high-humidity or coastal environments.

Compliance, testing and certification

This product family is typically designed to meet common commercial standards:

• Ingress protection: IP66, indicating dust-tight construction plus protection from high-pressure water jets.

• Mechanical impact: IK ratings (typical IK08) for vandal resistance.

• Safety listings: UL, ENEC, CE, or regional equivalents depending on market.

• Energy listings: DLC (DesignLights Consortium) or local rebate programs where applicable.

• Photometric testing: LM79 for complete fixture reporting and LM80 for LED package stability.

Ask suppliers for test documentation that corresponds to your market and project requirements.

Comparative value and replacement planning

LED replacements typically produce immediate energy reductions compared with HID sources.

• Example rule of thumb: a 150W LED fixture often replaces a 400W metal halide or HPS fixture with superior optical control. This reduces energy draw and cuts maintenance cycles.

Savings arise from efficacy, dimming strategies and longer lamp life that lowers maintenance labor and disposal costs. When modeling payback, include installation labor, available rebates, expected operating hours and maintenance avoided.

Total cost of ownership considers fixture longevity, warranty period and expected driver replacements. A higher initial cost unit with superior optics and a strong warranty often gives better lifecycle economics.

Routine maintenance and troubleshooting

Maintenance needs are modest but essential. Periodic checks:

• Clean lenses to maintain output.

• Inspect gaskets and fasteners for integrity.

• Verify sensors and photocells for correct operation.

• Check driver compartment for ingress or moisture.

Common trouble symptoms and remedies:

• Flicker: check driver compatibility with dimming controls and sensor configurations.

• Reduced lumen output: verify lens cleanliness and confirm driver current and ambient temperature.

• Moisture in housing: inspect gasket seating and venting breather; replace failed gasket.

• Sensor non-response: replace or recalibrate sensor; check power and wiring.

Keep spare drivers and LED boards on hand for critical sites to minimize outage durations.

Installation checklist (quick)

• Confirm pole size and mount type.

• Verify incoming voltage and phase.

• Ensure adequate torque on stainless fasteners.

• Seal conduit with outdoor-rated compound.

• Program photocell or dimming profile before final closure.

• Record serial numbers and take a photograph for asset records.

Warranty and service options

Typical warranty spans 3–7 years depending on configuration and reseller terms. Warranty commonly covers LED lumen maintenance and driver function under specified ambient conditions.

Warranty exclusions often include misuse, lightning damage, and installation outside specified voltage or temperature ranges. For high-reliability projects, negotiate extended warranty or service-level agreements that include rapid replacement.

Environmental considerations

• Energy reduction reduces carbon footprint by lowering site electricity use.

• Long-life LEDs reduce landfill waste tied to frequent lamp changes.

• Request reclaim or recycling programs for old HID ballasts, lamps and fixtures.

Example application scenarios

2. Multi-storey car park entries: use 50W wall-mounted versions at 3–4 m for glare-controlled illumination.

3. Large sports-adjacent lots: 200W fixtures on 8–10 m poles with Type V for uniformity.

4. Industrial yard: ruggedized 150–200W fixtures with microwave sensors and high-temperature-rated drivers.

Frequently asked questions

Q1: What does IP66 mean for an outdoor LED fixture?
IP66 means the enclosure is dust-tight and resists high-pressure water jets from every direction. That rating is suitable for most exterior environments exposed to heavy rain or wash-down procedures.

Q2: How do I choose between 100W and 150W for a retail parking lot?
Select based on pole height and target horizontal illuminance. For 4–6 m heights, 100W often provides proper lux for aisles; for larger spans or higher mounting, pick 150W to keep uniformity high. Perform a photometric layout to confirm spacing and uniformity.

Q3: Can these fixtures be dimmed and connected to building controls?
Yes. They support 0–10V dimming commonly, with DALI available for addressable schemes. Photocells and on-board sensors can be integrated for automated operation.

Q4: What is the expected lumen maintenance or lifetime?
Well-designed fixtures with good thermal paths typically achieve L70 lifetimes of 50,000–100,000 hours. Actual lifetime depends on ambient temperature, run hours and driver environment. Request LM79/LM80 test data for specific claims.

Q5: Which mounting is fastest for retrofits on round poles?
Slip fitter mounts are widely used for retrofit work on round poles. They reduce labor because they fit common pole diameters and allow small tilt adjustments.

Q6: Do these lights reduce maintenance compared to HID?
Yes. LEDs have longer life, no ballast changes, faster on/off cycles and fewer photometric shifts over time. Lower replacement frequency reduces labor and material costs.

Q7: What about glare and light trespass control?
Choose optics with cutoff or shield options and select beam types that focus light onto the target area. Baffles, house-side shields and precise distributions control spill and reduce complaints.

Q8: Are there rebates or incentives for installing LED parking lights?
Many utilities and regional programs offer rebates for high-efficiency commercial fixtures or for installations that meet performance thresholds. Check local energy efficiency programs when budgeting.
