The Hospital lit touchdown/positioning and lit cross helipad marking system (Circle-X) is Orga’s contribution to improve helicopter transportation of patients to and from hospitals, during times of low ambient light (twilight/night).

This lighting system supports smoother and more controlled landing, reduces risks, and makes sure your helipad meets the safety requirements. The robust and reliable LED lighting system eliminates the dangerous and disorienting ‘black-hole’ effect and provides pilots with the best possible visual cues during approach and landing of the helicopter.

Designed to allow smooth trolly access the system allows seamless patient transfer, and through its modular design the lighting system installation time is minimalised. Its strong, flexible and low profile metal parts allow landing of both wheel and skidded helicopters. This makes the Circle-X a reliable and sustainable solution.
