L550-XXX- HHS/SRO + INFRARED SE
Helicopter Hoist Status &/or Search and Rescue light
The L550-HHS/SRO lights combines the helicopter hoist light (HHS) and the Search and Rescue Operations light (SRO) in one fixture. A separate HHS or SRO IR light is also available. This light is optimized for use in Offshore environments. The light for helicopter hoist operation is a green status light, which is flashing or steady burning to indicate the hoist status. The SRO is a steady burning red + infrared light to indicate target turbines in emergency cases. The lights incorporates the benefits of advanced LED, optical and system control technologies to meet the most demanding applications.
