Low-intensity obstruction light LP411A

for helidecksexplosion-proofLED

Overview
The TD/PM H-light TD/PM H-light suitable for offshore helipads is designed for use on offshore oil platforms, ship aprons and other hazardous helideck environments. It is explosion-proof with ATEX and IECEx certification for gas zones 1 and 2 and is rated for IIA/IIB/IIC atmospheres and temperature classes T1–T6.

Features

• Stainless steel 316 housing providing corrosion and vibration resistance; IP67 protection suitable for exposed offshore conditions.
• Professional photometric design with high- and low-temperature resistant PC lens to ensure stable long-term photometric performance.
• Dimming options: supports PWM or RS485 (0–100) for stepless dimming to reduce glare during pilot approach.

Applications

• Offshore helipads
• Offshore oil platforms
• Ship aprons and hazardous outdoor helidecks
