January 4, 2013 - Cooper Crouse-Hinds upgraded its AB12 series of T8 fluorescent lamps with a T8 LED Ex-approved version, which 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 T85 deg C for dust applications.
The AB12 LED series is available in three sizes, 9W, 18W, and 25W. These sizes are equivalent to fluorescent tube sizes of 18W, 36W, and 58W. Replacing an AB12 T8 fluorescent lamp with the new T8 AB12 LED lamp can therefore provide up to 50 percent energy savings.
The AB12 220 LED has a rated current of 0.08A, with 2 x T8 LED tubes and a luminous flux rating of 720 lm. The AB12 240 LED has a current rating of 0.16A, with 2 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 2 x T8 LED tubes and a luminous flux rating of 2,000 lm. All three models have a rated voltage of 85-265V AC.
