With its screw-on traffic wand, Pelican's new 2490 LED makes flight deck FOD (foreign object damage) a thing of the past. Powered by 4AA batteries, the 2490 LED's produces 64 lumens of clean bright light to ensure maximum communication visibility. And, with a run time of 12 hours, the 2490 LED will outlast a full work shift, including over-time. At the bottom of a cargo hold or up on the flight deck, the light weight polymer body is corrosion proof, resistant to extreme temperatures, and is weather resistant using an O-Ring sealed shroud and wand. The 2490 LED: FOD-proof traffic wand.
