Features
- IIB gas group, T6 — read the group on the nameplate against the area classification: this series is marked IIB, so an area classified as IIC needs a different luminaire in the range.
- One or two tubes — 1×9 W, 2×9 W, 1×18 W or 2×18 W, so the output is matched to the space.
- Clear tube guards and cast end caps — the tubes sit behind guards with cast ends, as shown in the drawing.
- Gas and dust marking — Ex db IIB T6 Gb and Ex tb IIIC T80°C Db on the same luminaire.
- G1/2" cable entry — closed with the matching certified gland.
- Emergency version optional — for escape routes and areas where the general lighting may be switched off.
- Stainless mounting brackets — as shown in the specification sheet drawing.
- AC 220 V / 50 Hz — standard single-phase supply.
Where the BPY is used
- Corridors, stairwells and service passages that need linear lighting at a low mounting height
- Tunnels, culverts and cable routes where the luminaire has to follow the run
- Workshops and maintenance bays on projects whose spares list is built around fluorescent tubes
- Escape routes, using the optional emergency version
- Dust-rated areas, using the Ex tb IIIC T80°C Db marking
