Helideck obstruction light LP3

LEDexplosion-prooffor hazardous areas

Overview
LP3 helideck perimeter light designed for offshore and vessel helideck perimeter marking on moving and permanent platforms. Certified for use in explosive gas atmospheres (Zone 1 and Zone 2), gas groups IIA / IIB / IIC and temperature classes T1–T6.

Key features

• Stainless steel 316 housing for corrosion and vibration resistance in marine environments.
• Professional photometric design with high/low temperature resistant PC lens for long-term performance.
• Tempered glass cover; operational down to -50°C; 4 J shock resistance; thermal shock resistant and rated to 5 MPa static pressure.
• LED light source with thermal management keeping LED chip temperature below 85°C during operation.
• Dimming: stepless dimming via PWM or RS485 (0–100%) to reduce glare during pilot approach.
• Electromagnetic compatibility (EMC) compliant.

Product description and application
Applicable to offshore helideck perimeter lighting on moving and permanent platforms, including offshore oil & gas platforms, floating units and vessel helidecks. Suitable for hazardous offshore areas where explosion-proof certification and robust environmental resistance are required.
