A 100W UFO LED High Bay Light is a compact, industrial-grade fixture designed to efficiently illuminate large spaces with ceilings between 10 and 18 feet, such as warehouses, workshops, and garages. Named for its distinct round, flying-saucer shape, the heavy-duty die-cast aluminum housing functions as an open-finned heat sink that naturally dissipates thermal energy away from the internal electronics. This thermal management ensures the fixture achieves an exceptionally long lifespan of over 50,000 hours, while rugged IP65 water and dust-resistance ratings allow it to withstand harsh industrial environments.
Performance-wise, the light operates at a highly efficient 160 to 180 lumens per watt, generating a powerful daylight-white output of roughly 16,000 to 18,000 lumens while cutting energy consumption by over 60% compared to legacy metal halide fixtures. It is an isolated top-mounted driver that handles universal voltages and supports 0-10V dimming systems for customizable control. Typically projecting a wide 90-degree beam angle, these lights are designed to be hung via a simple hook-and-loop system and spaced 10 to 12 feet apart to provide bright, uniform, and shadow-free visibility across commercial workspaces.

100W UFO LED high bay light is best suited for indoor spaces with medium-height ceilings ranging from 10 to 18 feet. Because they produce roughly 16,000 to 18,000 lumens, using them on ceilings lower than 10 feet will cause blinding glare, while ceilings higher than 18 feet will leave the floor too dim.
The most common applications include:
Warehouses and Storage Facilities: Perfect for open storage areas and fulfillment centers with mid-height racking layouts, providing clear visibility for forklift operators and picking crews.
Commercial Workshops and Garages: Ideal for auto repair shops, detailing bays, and woodshops where bright, daylight-white (5000K) lighting is critical for precision work and safety.
Manufacturing and Assembly Plants: Used in light industrial facilities to eliminate shadows on assembly lines, helping workers inspect parts and read schematics accurately.
Pole Barns and Agricultural Buildings: Great for large equipment sheds, livestock barns, and indoor riding arenas due to their dust and water-resistant (IP65) construction.
Large Retail Spaces and Supermarkets: Often left exposed in big-box retail stores or wholesale clubs with open-ceiling designs to create a bright, inviting shopping environment.
1. Exceptional Energy Efficiency
Delivers powerful, flicker-free output of up to 18,000 lumens while consuming only 100W, directly replacing traditional 250W to 400W metal halide fixtures and slashing electricity consumption by 60% to 70%.
2. Superior Heat Dissipation
The die-cast aluminum housing functions as a highly efficient integrated heat sink, drawing heat away from the LEDs and protecting the internal electronics, which guarantees a lifespan exceeding 50,000 hours.
3. Durable and Robust Construction
Rated IP65 for complete dust-tight protection and resistance against water jets, ensuring reliable performance even in harsh industrial environments with airborne debris and moisture.
4. Low Maintenance Overhead
With an extended operational lifespan and rugged build quality, the fixture virtually eliminates the labor and material costs associated with frequent bulb replacements common in traditional lighting systems.
5. Flexible and Adaptable Design
It has a simple hook-mount design for quick and straightforward installation, plus built-in 0-10V dimming capabilities for customized lighting control based on occupancy or ambient conditions.
6. Enhanced Workplace Safety and Visibility
Provides bright, uniform, shadow-free illumination that improves visibility for workers, reduces eye strain, and helps prevent accidents in different industrial settings.
The 100W UFO LED high bay light comes with an advanced intelligent radar sensing control system that delivers dynamic energy savings without compromising illumination performance. With a large-angle sensing range and a detection distance of 10 to 12 meters, the fixture automatically responds to motion within its coverage area, adjusting brightness levels based on real-time occupancy detection.
When no movement is detected, the light dims to a low-power standby mode, significantly reducing energy consumption during idle periods. As soon as personnel or vehicles enter the sensing zone, the fixture instantly returns to full brightness, ensuring optimal visibility exactly when and where it is needed. This intelligent on-demand operation maximizes energy efficiency, extends the lifespan of the fixture, and makes it an ideal choice for warehouses, workshops, parking areas, and other large spaces where occupancy patterns are intermittent rather than continuous.

Q1: What is the recommended mounting height for this 100W UFO LED high bay light?
A: This fixture is optimally suited for ceilings between 10 and 18 feet (approximately 3 to 5.5 meters). When mounted below 10 feet, the high luminous output may cause uncomfortable glare; when installed above 18 feet, the floor-level illuminance may drop below adequate working levels. For ceiling heights outside this range, we recommend considering other wattage options available in our UFO high bay series.
Q2: What is the actual lumen output and how much energy can I save compared to traditional lighting?
A: The 100W model delivers approximately 16,000 to 18,000 lumens, with a luminous efficacy of 160–180 lm/W. It directly replaces conventional 250W to 400W metal halide or high-pressure sodium systems, achieving energy savings of 60% to 70%. This translates into substantial reductions in electricity costs while maintaining superior brightness and light quality.
Q3: Is this fixture suitable for outdoor or damp environments?
A: The housing carries an IP65 ingress protection rating, providing effective resistance against dust and moisture. While it is well-suited for humid or dusty indoor environments such as warehouses, workshops, and agricultural buildings—it is primarily designed for indoor use. For full outdoor applications, we recommend consulting our sales team for appropriate alternatives with additional weatherproofing attribute.
Q4: Does this light support dimming or integration with control systems?
A: Yes. The fixture is an isolated top-mounted driver that supports 0–10V dimming controls, as well as compatibility with timers and motion sensors. This allows for flexible lighting management and additional energy savings by adjusting output based on occupancy or ambient conditions.
Q5: What is the warranty and what does it cover?
A: The product is backed by a comprehensive 5-year warranty. During this period, we offer a 1:1 replacement for any defects in materials or workmanship. Additionally, our quality assurance process includes four rounds of 100% inspection and a 24-hour aging test before shipment, ensuring that every unit meets strict performance and reliability standards before it leaves our factory.
