Energy efficient LED lighting for hazardous areasEnergy efficient lighting specialist Cooper Crouse-Hinds has extended and upgraded its established AB12 series of T8 fluorescent lamps with a new T8 LED Ex-approved version. The unit is certified for use in Zone 1 and 2 hazardous gas and Zone 21 and 22 hazardous dust environments.

The fourth supplement of the AB12 certification LOM 02 ATEX 2013X (dated 11.10.2011) now allows for “the use of T8 LED tubes with direct mains supply up to 277V and consumed power up to 50W per tube”. The temperature class of the AB12 LED series is T6 for gas and T85degC for dust applications.

“Nowadays, customers are asking for hazardous area LED lighting not only for energy saving reasons, but also for environmental reasons,” said Willi Steckel, the company's Product Line Manager IEC Lighting. “Statutory environmental regulations are becoming more and more important in certain countries and areas of the world.”

There are three sizes offered in the new AB12 series — 9, 18 and 25W. These are equivalent to fluorescent tube sizes of 18, 36 and 58W, so replacing an AB12 T8 fluorescent lamp with the new T8 AB12 LED lamp can provide up to 50 per cent energy savings.

The AB12 220 LED has a rated current of 0.08A, with two x T8 LED tubes and a luminous flux rating of 720 lm, while the AB12 240 LED has a current rating of 0.16A, with two x T8 LED tubes and a luminous flux rating of 1440 lm. The third option in the series, the AB12 265 LED, has a rated current of 0.22A, with two x T8 LED tubes and a luminous flux rating of 2000 lm. All three models have a rated voltage of 85-265V AC.
