Cortem LIFEX-M Ex LED Linear Lighting Fixture

Name: Cortem LIFEX-M Ex LED Linear Luminaire – Datasheet & Quote
Brand: Cortem
SKU: LIFEX-M

Description

Native LED linear luminaire for hazardous corridors, plant rooms and offshore decks

The Cortem LIFEX-M is a linear LED luminaire in extruded aluminium for hazardous areas. Cortem describes it as the first native LED linear fixture of its range, designed to be compact, light and easy to install or retrofit, with a bracket system that has no fixed fixing distance and lets the luminaire be rotated by minus 30, 0 or plus 30 degrees.

The range comes in two versions. The LifEx-ME is marked II 2GD Ex db eb mb IIC T.. Gb and Ex tb IIIC T..°C Db for Zones 1, 2, 21 and 22. The LifEx-MN is marked II 3G Ex nR IIC T.. Gc with the same dust marking, for Zones 2, 21 and 22. Both are rated IP66, and Cortem states that the fixtures have passed vibration, surge and soft-start tests beyond the minimum standards.

Selection table highlights (ME version)

Cortem tabulates real power, rated power, supply voltage, temperature class, lumen output, efficiency and weight for each code. The following rows are taken from the ME table at 40 degrees C ambient.

Code	Real power	Supply	Lumens	Temp. class / surface	Length
LifEx-ME-0315	13.9 W	220-240 V	1,865 lm	T6 / 57 °C	541 mm
LifEx-ME-0630	26.2 W	110-277 V	3,677 lm	T6 / 80 °C	840 mm
LifEx-ME-0660	54.5 W	110-277 V	8,011 lm	T5 / 95 °C	840 mm
LifEx-ME-1230	29.0 W	110-277 V	4,112 lm	T6 / 60 °C	1,398 mm
LifEx-ME-1290	79.3 W	120-277 V	12,228 lm	T5 / 89 °C	1,398 mm
LifEx-ME-12120	102.6 W	220-277 V	16,029 lm	T5 / 91 °C	1,398 mm
LifEx-ME-1590	78.6 W	120-277 V	11,926 lm	T5 / 89 °C	1,738 mm

The code logic reads as length (03 for 300 mm, 06 for 600 mm, 12 for 1200 mm, 15 for 1500 mm) followed by power. Suffixes N, E, NH and EH select normal plus emergency, emergency only, and the -60 degree C battery-heater versions.

Options and installation points

Cortem offers a pole fastening mechanism, a protective cage, coloured LED strips, a battery box for easier emergency battery replacement, wiring-through versions, DALI dimming on request, and cable glands, plugs and Fast-Ex electrical connectors. Emergency units use a Ni-MH battery of 1.8 or 3 Ah with a green charge indicator.

Check the temperature class against the highest local ambient, because the surface temperature rises with ambient and with power. Install to EN 60079-14, use glands and plugs that carry the same certification, and keep the certificate with the plant records.
