High-Bay Luminaires
High-bay luminaires are high-lumen LED lighting fixtures specifically designed for industrial facilities, logistics warehouses, sports halls, and large retail spaces with ceiling heights above 5 metres. They are rapidly replacing traditional metal halide and high-pressure sodium lamps, providing 50-65% energy savings and 4-5 times longer lifetime.
Reference values: 4000K-5000K colour temperature · 13,000-45,000 lumens · CRI ≥ 80 · IP65 · 50,000-100,000-hour L80 lifetime
What Are High-Bay Luminaires?
High-bay luminaires feature a different optical design compared to luminaires used in conventional low-ceiling environments. Special reflectors or lens systems are utilized to ensure uniform light distribution from the ceiling to the floor, eliminate shadow zones, and provide coverage over large areas.
Types of High-Bay Luminaires
UFO (Round) High-Bay
The traditional form featuring a compact round housing and high lumen density. Typical power range is 100-200W with 13,000-25,000 lumens. Ideal for large open spaces.
Linear High-Bay
An elongated linear form with a modern industrial design. It also illuminates shelving surfaces within warehouse aisles and creates softer shadows. This configuration is becoming increasingly popular in logistics warehouses.
Selection According to Ceiling Height
- 5-7 metres: 100-150W, 13,000-20,000 lumens, 90°-120° wide beam angle
- 7-10 metres: 150-200W, 20,000-28,000 lumens, 60°-90° beam angle
- 10-15 metres: 200-300W, 28,000-40,000 lumens, 60°-90° beam angle
- 15+ metres: 300W+, narrow beam angle (45°-60°), focused illumination
Applications
- Industrial manufacturing facilities: High illuminance levels, elimination of shadow zones, improved occupational safety
- Logistics warehouses: Warehouse aisles, shipping areas, and long operating-hour environments
- Sports halls: 4000K-5000K, flicker-free lighting suitable for video broadcasting
- Hangars and assembly areas: High lumen output and wide area coverage
- Large retail stores and hypermarkets: A modern minimalist alternative lighting solution
Technical Criteria
IP Protection and Durability
IP65 is the minimum standard for industrial environments. IP66-rated luminaires are required for washable food processing facilities, while ATEX-certified models are necessary for explosive atmospheres.
Driver Quality
Surge protection ≥ 10kV (critical for lightning protection), flicker-free drivers, operating temperature range from -30°C to +50°C, and efficiency above 95%. PIR sensor integration can provide energy savings of 40-50%.
Lifetime and Lumen Maintenance
Premium industrial models offer an L80 lifetime of 70,000-100,000 hours. Since maintenance and replacement are costly in high-ceiling applications, lifetime is a critical selection criterion.

Frequently Asked Questions
Should I choose UFO or linear high-bay luminaires?
For large open areas such as manufacturing facilities and hangars, UFO high-bay luminaires are generally the more economical and sufficient solution. In logistics warehouses with shelving aisles, linear high-bay luminaires also illuminate the rack surfaces, providing a more uniform lighting result.
Does it make sense to replace my existing metal halide luminaires with LED high-bay luminaires?
Absolutely. A 400W metal halide luminaire can typically be replaced by a 150W LED high-bay luminaire while achieving a similar illuminance level, resulting in approximately 62% energy savings. For a medium-sized facility with around 100 luminaires, annual electricity savings can range between 600,000 and 800,000 TL, with a typical payback period of 20-26 months.
How do motion sensors operate in industrial environments?
Unoccupied warehouse aisles can remain at a 20% security lighting level and automatically increase to 100% output when motion is detected. In logistics warehouses, this can provide an additional 40-50% energy saving.
Is an ATEX-certified high-bay luminaire required?
ATEX certification is mandatory in environments containing explosive gases or combustible dust, such as oil and gas facilities, chemical plants, and ammunition manufacturing facilities. It is not required in standard industrial environments. The appropriate certification classification (Zone 1, 2, 21, or 22) should be determined according to the specific facility conditions.
