A new range of explosion-proof light fittings for T5 bi-pin fluorescent lamps (16mm diameter), has been launched by Cooper Crouse-Hinds.

The new nLLK 10 Ex-light fittings are certified for use in Zones 2 and 22 in accordance with the European Directive (ATEX) and the IECEx standards. The series includes all the features of the company’s existing nLLK 08 series Ex-light fittings for Zone2/21 T8 fluorescent lamps (26mm diameter), but is also fitted with special Luxtronic EVG electronic ballast technology (including End-Of-Life set-up and switch-off), which provides improved safety, lighting quality and energy savings.

The EOL circuit enables the lamp to be monitored and switched off safely when the End-Of-Life has been reached. The nLLK 10 series is well suited for indoor use in Zone 2/22 hazardous gas and dust areas, including oil refineries, chemical plants, onshore and offshore installations. The light fittings are also suitable for outdoor use in high ambient temperatures. The new series is protected to IP66 and operates in ambient temperatures from -25°C to 50°C. Rated voltage is 220-240V AC/DC, 50/60 Hz.

The nLLK 10 series is currently available in two sizes – 2 x 14W HE and 2 x 28W HE. These versions can be fitted to the housings of existing nLLK 08, 18W or 36W T8 lamps, with or without through wiring. A 2 x 35W HE version of the nLLK 10 series will be available later in 2011.
