2000W HID to 750W LED Retrofit Guide | Port High Mast Lighting Upgrade

Photometric Strategy for Replacing Traditional HID High Mast Lights on 30m Port Masts

Quick Answer: Can a 750W LED Replace a 2000W HID High Mast Light?

Yes. A 750W LED high mast light can replace a traditional 2000W metal halide (HID) floodlight when the retrofit is designed through photometric analysis rather than a simple watt-for-watt replacement.

For a typical 30m port high mast , the recommended LED retrofit approach is to replace the existing HID ring with FORTOMO 40SL750 LED high mast floodlights , using optimized NEMA beam angles and professional aiming.

A properly designed LED retrofit can achieve:

  • 30–50 lux maintained illumination for container yards and port aprons
  • Improved lighting uniformity (Emin/Eavg approximately 0.25–0.4)
  • 55–65% energy reduction compared with traditional HID systems
  • Reduced maintenance requirements at high mast installation heights
  • Better glare control for crane operators and vehicle drivers

FORTOMO 40SL750 delivers:

  • 112,500–127,500 lumens
  • 150–170 lm/W efficiency
  • 500W–750W power options
  • IP66 protection
  • NEMA optical solutions for large-area lighting

Why Ports Are Replacing 2000W HID High Mast Lighting

For decades, metal halide (MH) and other HID lighting systems were widely used in ports, container yards, and industrial terminals.

However, high mast environments expose HID systems to several operational challenges.

1. High Maintenance Costs

A 30m high mast requires specialized equipment for maintenance.

Traditional HID systems typically require:

  • Regular lamp replacement
  • Crane or lifting equipment
  • Longer maintenance downtime
  • Increased labor costs

LED high mast lighting reduces these maintenance requirements through longer lifespan and improved reliability.

2. Rapid Lumen Depreciation

Traditional HID fixtures experience significant lumen reduction during operation.

Typical issues include:

  • Reduced brightness after continuous operation
  • Lower maintained illumination
  • Uneven lighting performance between maintenance cycles

LED systems maintain more stable output over their operating life, making them better suited for critical port operations.

3. Slow Restart Performance

HID lamps require warm-up and restrike time.

After power interruption:

  • Metal halide systems may require several minutes to restart
  • Security lighting response is delayed

LED high mast lights provide instant startup, improving operational safety in ports and logistics areas.

4. Poor Optical Control

Traditional HID floodlights often use symmetrical reflectors, which can create:

  • Excessive glare
  • Light spill toward surrounding areas
  • Poor uniformity between mast locations

Modern LED optics allow each fixture to be precisely aimed according to the lighting layout.

Photometric Retrofit Calculation for a 30m Port Mast

A successful HID-to-LED conversion requires lighting calculation based on:

  • Mast height
  • Target illuminance
  • Coverage area
  • Maintenance factor
  • Beam distribution
  • Fixture aiming angle

Typical Port Lighting Conditions

Project example:

  • Mast height: 30m
  • Application: Container stacking yard
  • Target illumination:
    • 30 lux for general yard areas
    • 50 lux for crane and operational zones
  • Maintenance factor: 0.8 for LED systems

Coverage estimation:

30m mast height × 2–2.5 coverage ratio = approximately 60–75m lighting radius

A single mast can typically cover:

1.1–1.8 hectares depending on layout and lighting requirements.

Example Retrofit Design

Existing HID System

Typical configuration:

  • 6 × 2000W metal halide fixtures
  • Total connected load:

12,000W per mast

Initial lumen output:

160,000 lm × 6 fixtures

≈ 960,000 lumens

After lumen depreciation:

≈ 470,000 maintained lumens

LED Retrofit Solution

Using:

6 × FORTOMO 40SL750 LED floodlights

Output:

127,500 lm × 6 fixtures

≈ 765,000 initial lumens

Maintained output:

765,000 lm × 0.8 maintenance factor

≈ 612,000 maintained lumens

Result:

  • Similar or improved ground illumination
  • Better edge coverage
  • Lower energy consumption
  • Improved glare control
