1. What Is an LED Flood Light — and Why Does the Type Matter?
An LED flood light is a high-output, wide-beam luminaire designed to uniformly illuminate large outdoor or semi-outdoor spaces. Unlike narrow-beam spotlights, flood lights cast broad, even coverage across parking lots, stadiums, warehouses, port yards, and building facades.
The LED revolution has made traditional halogen and metal halide flood lights obsolete. Today’s professional-grade LED flood lights achieve 100–200 lm/W efficacy, 50,000+ hour lifespans, and full smart-control integration — with payback periods typically under three years even at commercial scale.
But selecting the wrong type for your application is a costly mistake. A general-purpose flood light on a 30-meter high mast will fail to reach ground-level lux targets. A sealed fixture in a chemical plant environment corrodes within two years. And a non-dimmable unit on an automatic security installation wastes energy every night. The three series covered in this guide each solve a distinct problem.
Scope of this guide: We cover the LED Flood Lights GEN5, High Mast LED Flood Lights, and Modular LED Flood Lights from Haichang Optotech.
2. Six Key Factors to Evaluate Before You Buy
Before comparing specific product series, map your project against these six dimensions. They will drive 90% of your purchase decision.
2.1 Wattage and Lumen Output (Efficacy)
Never specify by wattage alone. Two 200W flood lights can produce vastly different ground-level lux depending on efficacy (lm/W), beam angle, and mounting height. The GEN5 achieves up to 130 lm/W with Philips Lumileds; the High Mast series reaches 100–200 lm/W optimised for long-throw projection.
2.2 IP and IK Rating
IP66 protects against high-pressure water jets — the standard for all three series covered here. IK10 adds 20-joule mechanical impact resistance, critical for public-facing installations. Avoid IP65-only fixtures for heavy industrial or coastal deployments.
2.3 Mounting Height
This single factor often determines which series is appropriate: ground-level to roughly 20m suits the GEN5; 20m–40m high-mast poles require the dedicated High Mast series with long-throw optics; the Modular series is mounting-height-agnostic and prioritises maintenance access over height optimisation.
2.4 Maintenance Accessibility
If replacing a fixture requires a crane, scaffold, or production shutdown, the Modular series’ hot-pluggable LED engine system reduces that event to a seconds-long module swap — no tools, no downtime, no full-fixture cost.
2.5 Smart Control Requirements
Dusk-to-dawn photocell sensing, PIR motion detection, CCT adjustment, and three-step power dimming are native GEN5 features. The High Mast series supports Photocell, motion sensor, DALI, 0-10V, and DMX for professional area lighting control.
2.6 Certifications
CE and RoHS are the baseline for European and international tenders. All three series carry both. Stainless-steel bracket options are available on the High Mast series for coastal/saline environments.
Pro tip: Always request a DIALux or AGi32 photometric simulation from your supplier before finalising wattage and quantity. Haichang provides IES/LDT files and simulation support free of charge.
3. LED Flood Lights GEN5: The Smart All-Rounder (10W–600W)
Haichang’s fifth-generation outdoor flood light platform is the most versatile in the lineup, covering power outputs from 10W to 600W across 12 models. It is designed to replace Philips Hue and Ledvance halogen outdoor floodlights while delivering superior efficiency, smart sensing, and best-in-class weatherproofing.
Compared to standard IP65 flood lights, the GEN5 features a robust IP66 + IK10 body with completely vapour-free construction — eliminating condensation-related failures common in humid and coastal climates. CCT and power adjustment are available as factory options, and dimmable drivers are standard.

4. High Mast LED Flood Lights: Built for Height and Power (200W–1800W)
Haichang’s High Mast LED Flood Light is a patented design engineered for large expansive outdoor areas requiring reliable coverage from extremely high mounting points. Each fixture delivers 200W to 1800W by accommodating 1 to 6 individual LED modules (light engines), making it a direct replacement for traditional 750W–2000W metal halide high-intensity discharge (HID) systems — with up to 80% energy savings and dramatically reduced maintenance cost.
The unique patented LED light module system enables tool-less onsite replacement, reducing maintenance costs at difficult-to-access heights. Multiple beam angle options — 10° / 15° / 20° / 25° / 30° / 40° / 45° / 60° / 90° — allow precise photometric matching to any pole height and area geometry. Stainless steel brackets are available for coastal and saline environments.

5. Modular LED Flood Lights: Industrial-Grade Hot-Plug Maintenance
The Modular LED Flood Light represents a fundamentally different engineering philosophy from conventional flood lights. Instead of a sealed fixed-output fixture, it uses a hot-pluggable LED engine module system — individual power modules that can be inserted, removed, or replaced on-site without disconnecting power, using specialised tools, or sending the unit back to the factory.
This architecture solves two critical industrial problems simultaneously. First, it enables power scalability: the same housing frame delivers different total output by fitting more or fewer LED engine modules. Second, it enables zero-downtime maintenance: a failed module is swapped in seconds while remaining modules continue operating. The fixture’s integral heat-sinking design at both module and housing level makes it suitable for high-ambient-temperature environments — including chemical factories, refineries, and dock facilities — where conventional aluminium flood lights throttle output or fail prematurely.
5.1 Modular LED Flood Light Key Features
- Hot-pluggable LED engine modules — live field replacement, no shutdown required
- Scalable output — configure total wattage by number of installed modules
- Integral module-level + housing-level heat sinking for extreme ambient temperatures
- Chemical-resistant housing coating — rated for corrosive industrial environments
- IP66 waterproof protection
- Engineered for 24/7 continuous operation without degradation
- Lowest 10-year total cost of ownership (TCO) in harsh environments
- Lifespan: L70 @ ≥50,000 hours per module
- CE, RoHS certified
5.2 Why Hot-Plug Matters for Industrial Facilities
Conventional flood lights in chemical, corrosive, or high-humidity environments typically require full-fixture replacement within 2–3 years. At elevated mounting points, that means crane hire, production shutdown, and full fixture cost. With the Modular series, a technician replaces only the failed LED engine module — a fraction of the fixture price — while production continues uninterrupted. Facilities operating 24/7 consistently report 40–60% lower maintenance expenditure over a 10-year period compared to standard industrial flood lights.
5.3 Typical Applications for Modular LED Flood Lights
Chemical factories, docks and port facilities, oil and gas plants, refineries, heavy manufacturing, power generation plants, corrosive or high-humidity industrial environments, and any facility where unplanned downtime carries a significant operational cost.

8. Frequently Asked Questions
What is the difference between IP65 and IP66 for outdoor LED flood lights?
IP65 protects against low-pressure water jets from any direction. IP66 protects against high-pressure water jets — the kind produced by industrial hose-down equipment, heavy rain, and pressure washers. For commercial and industrial outdoor flood lights, IP66 is the recommended minimum. All three Haichang series covered in this guide carry IP66 certification.
How do I calculate how many watts I need for a parking lot or sports field?
You need to define the target illuminance (lux) for your application, then work backwards using lumen output, beam angle, and mounting height. As a general reference: parking lots typically require 20–50 lux average; amateur sports facilities need 200–500 lux; professional stadiums require 1,000–2,000+ lux. Contact Haichang with your area dimensions and mounting height for a free DIALux simulation.
What does CCT adjustable mean and why does it matter?
CCT (Correlated Color Temperature) is measured in Kelvin. Lower values (2700K–3000K) produce warm white; 4000K produces neutral white; 5000K–6500K produces cool daylight white. The GEN5 series allows field adjustment between 3000K, 4000K, 5000K, and 6500K — enabling a single SKU to serve both warm architectural and cool security lighting without ordering different products.
What power range does the High Mast LED Flood Light cover?
The High Mast series covers 200W to 1800W by accommodating 1 to 6 individual LED modules per fixture. This makes it a direct replacement for traditional 750W–2000W metal halide HID systems, saving up to 80% in energy costs while eliminating frequent ballast and lamp maintenance.
What is hot-pluggable LED engine technology in the Modular series?
Hot-pluggable means a failed or aging LED engine module can be physically removed and replaced while the fixture remains powered and other modules continue operating — no shutdown, no specialist tools, no full-fixture replacement cost. For 24/7 industrial facilities, this capability eliminates the largest hidden cost in outdoor lighting: unplanned maintenance downtime.
How long do Haichang LED flood lights last and what warranty do they carry?
All three series are rated at L70 @ ≥50,000 hours — at 50,000 hours, at least 70% of units will still produce 70% of original lumen output. At 12 hours per day operation, this represents over 11 years of service life. The GEN5 and High Mast series both carry a 5-year solid warranty.
What is IK10 and which series offers it?
IK10 is the highest rating under IEC 62262, indicating the luminaire withstands a 20-joule mechanical impact — equivalent to a 5 kg mass dropped from 40 cm. It is essential for public-facing installations subject to vandalism or accidental impact. The GEN5 series carries IK10 as standard; the High Mast series also carries IK10 rating.
Does the High Mast series support DALI dimming?
Yes. The High Mast LED Flood Light supports multiple dimming control protocols: DALI, 0-10V, and DMX, in addition to Photocell dusk-to-dawn sensing and motion sensor dimming (to 20% output during unoccupied periods). This makes it fully compatible with professional building management and stadium control systems.
