CAP 437 explosion proof LED heliport identification marking light panel used in conjunction with a control panel and the Heliport Identification Marking (‘H’). Long life LEDs and light weight design, which is suitable for direct mounting on the helideck due to the low profile (<25mm), makes the product ideal for the environmental conditions as well as easy installation.
