Durable High-Performance LED High Bay Light Lens - Polished Borosilicate Glass

1. Material Construction

• Core Material: Optical-grade borosilicate glass (Schott Borofloat®/equivalent)

• Surface Treatment: Precision optical polishing (Ra < 0.5nm surface roughness)

• Structural Enhancement: Chemically tempered for subsurface compression

2. Critical Properties

• Extreme Durability: IK10 impact rating (20J impact resistance) against falling tools/debris

• Thermal Resilience: Withstands ΔT >220°C (rapid cooling from 300°C→80°C)

• Optical Excellence: >94% visible light transmission (380-780nm) with <1% haze

• Chemical Resistance: Immune to alkaline cleaners, oils, and warehouse fumes

• UV Stability: Near-zero solarization after 50,000+ hours of 100W LED exposure

• Thermal Management: Withstands 150°C continuous operating temperatures

3. Core Functions

• Precision Beam Control: Engineered optics achieve 60°-120° batwing distribution eliminating ceiling shadows

• Lumen Maximization: <6% optical loss vs. polycarbonate (boosts usable lumens by 15-20%)

• Hazard Mitigation: Shatterproof design (EN 12150-1 compliant) contains fragments upon impact

• Environmental Sealing: Compatible with IP65/66 housings resisting dust/water ingress

• Maintenance Reduction: Non-yellowing surface avoids frequent cleaning/replacement

4. Industrial Applications

• Warehouse Lighting: 30-50ft ceiling high bays in distribution centers

• Manufacturing Facilities: Assembly line lighting with vibration resistance (ISO 2372 compliant)

• Cold Storage: Freezer-rated lenses (-40°C to +150°C operational range)

• Gymnasiums/Sports Arenas: High-impact protection from balls/equipment

• Aircraft Hangars: Fuel-fume resistant lighting solutions
