CATU CD-129
CATU CD-129 blue LED road flare signal lamps are used to alert and signal work on roads and railways. The LED signal lamps adhere to EN 61547 – IEC 61000-4-5:2014 and are supplied in a box which holds six 0.8 watt, 240 lumen LEDs and a 12V/24V car charger or 110V/220V wall charger.
When fully charged, the indicator light aside flares stop flashing and remain steady after 8 to 10 hours of usage. These blue LED signal lamps feature a simple start-up, several different lighting modes and are equipped with a magnet to enable the lamps to be fixed onto a metal surface.
CATU CD-129 have an impact resistant rating of IK07 and are waterproof to IP65.
