CAP437 LED helideck touchdown/positioning light panel used in conjunction with a control panel and the touchdown/positioning marking (Circle). Long life LEDs and light weight design, which is suitable for direct mounting on the helideck due to the low profile (<25 mm), makes the product ideal for the environmental conditions as well as easy installation.
