Features
- All-plastic construction — body and diffuser are plastic, which is what makes the lamp suitable for corrosive and frequently washed-down positions where a metal housing would need regular attention.
- One or two tubes — 1×9 W, 2×9 W, 1×18 W or 2×18 W, so the light output can be matched to the space rather than overspecified.
- Gas and dust marking — Ex db eb mb IIC T5 Gb and Ex tb IIIC T95°C Db on the same luminaire.
- Two lengths — a 771 mm and a 1400 mm version, on the same 215 × 130 mm section.
- Emergency version optional — for escape routes and areas where the general lighting may be switched off.
- M20 cable entry — closed with the matching certified gland.
- Supplied with brackets and fixings — as shown in the second photograph.
- AC 220 V / 50 Hz — standard single-phase supply.
Where the BYS is used
- Corrosive atmospheres where a metal housing would corrode, such as chemical and water-treatment areas
- Coastal and offshore installations exposed to salt-laden air
- Wash-down areas, where the luminaire is hosed down as part of the cleaning regime
- Walkways, tunnels and service corridors that need even linear lighting at a low mounting height
- Escape routes, using the optional emergency version
Not sure whether you need one tube or two?Tell us the length of the run, the mounting height and the level of light required, plus the zone, gas or dust group and the local environment. We will confirm the tube arrangement, the length and whether the emergency version applies.
Part of the explosion-proof lighting range, which also covers LED luminaires such as the ZBD154 floodlight and the ZBD124 maintenance-free light.
