New XLFE-4 obstruction lighting series

22 March 2012

Cortem’s new XLFE-4 obstruction lighting fixtures are suitable for installation on towers or high buildings as obstruction signals for aircraft and contain four high power LEDs. The use of LED technology provides low power consumption, long life (approx. 50.000 hours) and a reduction in maintenance costs.

Other advantages, according to Cortem, are improved visibility in critical environmental conditions, low environmental impact due to the absence of toxic and dangerous substances and minimum light pollution thanks to the well-defined directional beam. 

The lighting fixture consists of a body in aluminium alloy with low copper content RAL7035 painted, a globe made of borosilicate glass and stainless steel hardware. 

The internal part with light source comprises: LED plate, dissipator, power supply, support frame, connection terminal, polycarbonate reflector and  sealed diaphragm. “Ex de” execution allows the cable to enter through a non-armoured cablegland, making the product suitable for any type of system and environment. 

XLFE-4 with a red light and an intensity greater than 32 candles complies with ICAO (International Civil Aviation Organization) Standard Volume 1, 5th edition of June 2009, Annex 14. In accordance with the provisions of this Standard, the luminous flux is 360° on the ground plane and less than 10° in the vertical plane. 

This series belongs to the Low Intensity category of signalling fixtures. For applications not regulated by ICAO Directive, XLFE-4 lighting fixtures are also available in blue, yellow and green colours.
