Cortem XLFE-MIA Ex Medium Intensity Obstruction Light

Ex db eb LED obstruction light for flare stacks, towers and tall structures

The Cortem XLFE-MIA is a medium intensity LED obstruction light for hazardous areas, designed for Zone 1 with an Ex db optical source. The white flashing XLFE-MIA is rated above 20,000 candles in daytime operation and above 2,000 candles at night and complies with ICAO Annex 14 for medium intensity type A aviation obstruction lights. The fixed red XLFE-MIC, with more than 2,000 candles, covers medium intensity type C.

Cortem lists oil refineries, chemical and petrochemical plants, onshore and offshore plants, loading jetties, combustible liquid depots, high buildings and aircraft storage facilities as typical applications. The lamp body acts as both the explosion protection and the heat sink, which avoids resin-coated optics that can deteriorate over time.

Technical specifications of the XLFE-MIA and XLFE-MIC

System design and power supply

The XLFE-MIA is not a stand-alone device. It is part of a system powered from a control panel, which keeps the power supplies accessible and reduces maintenance at height. Cortem states that the system can manage failure control of the lamps, the switching on of spare indicators and synchronisation between panels by cable or GPS.

Available accessories include an Ex or watertight protected control panel, cable glands NAV20IB for non-armoured cable or NEV20IB for armoured cable, a heat shield and polyester painting.

Selecting and installing the light

Check with the aviation authority or plant operator which obstruction light type and quantity the structure needs, because the number of lights per level depends on the height and the regulation. Choose type A white for day and night operation or type C red where the regulation permits.

Check the site ambient against the two ranges in the datasheet, minus 40 to plus 40 degrees C and minus 40 to plus 60 degrees C, and confirm the temperature class on the certificate. Terminate the M20 entry with a certified gland, keep the panel in a safe area or an Ex enclosure, and mount the fixture with its anodised base as shown in the datasheet dimensional drawings.
