Applications

Semi-flush perimeter light helps mark helipad touchdown and lift-off area (TLOF) and/or final approach and takeoff area (FATO) for metal helidecks and pavement heliports.

Why Our HL-492L is Better

• Recessed, semi-flush mounted, allows for obstruction-free movement of equipment and personnel.
• Small 6" fixture easily drops into metal helideck, fastens with 4 bolts.
• Corrosion resistant hard anodized finish suitable for marine environments and available in many different colors.
• Fixture sealed to bottom cover to prevent moisture intrusion.
• Lightweight and robust aluminum alloy construction.
• Prism removal and replacement achieved without need for adhesives or sealants.
• Pre-focused optics simplify maintenance.
• Cost-saving, energy-efficient LEDs.
• Power adapter included.
• Low maintenance - LED light source has 50,000 hour lifetime (50X longer than halogen).
• Monochromatic output of LEDs is more conspicuous than halogen.
• Pilots prefer LED over halogen because of increased visibility.
• Fixture can be used with 100-240VAC or 10-30VDC.
• Direct retrofit, drop in replacement. Factory retrofits available for your existing halogen fixtures.
• With our Dimming Controller option, the lights can be dimmed at night to reduce glare - select from three brightness levels.
• Available for non-heliport applications such as architectural lighting.
