The Stone Series is a high-performance, explosion-proof lighting solution designed for Zone 1 and Zone 2 hazardous areas. Its slim linear design makes it ideal for industrial environments such as petrochemical plants, manufacturing facilities, and processing areas.

Built from copper-free aluminium with a UV-stabilised polycarbonate diffuser, it features IP66 ingress protection and IK08 impact resistance for reliable use in harsh conditions. Delivering up to 139 lm/W with L70 ≥100,000 hours, it ensures energy-efficient, low-maintenance operation.

With a wide -40°C to +55°C operating range, multiple mounting options, and ATEX & IECEx certification, the Stone Series is a durable, versatile solution for general-purpose hazardous area lighting.

Polar: solid green C0–C180, dashed blue C90–C270, dotted amber the plane through the brightest direction when it lies between them; rings at 25% steps of the peak. Isolux: the footprint on the floor with the fitting aimed straight down, contours at 50%, 25% and 10% of the brightest point, grid in mounting heights (H). Both are drawn from the first measured file for that optic.

Wire-in-wire-out products are supplied with one non-armoured ATEX certified gland and one ATEX certified blanking plug. Armoured cable glands are an option; contact Kellwood.

The stated cable size applies to the standard gland; armoured cable may vary.

If more than one modification is required, separate each modification with a hyphen at the end of the product code.

Modifications which affect light output have separate photometric files identified with +(modification).

Alternative drivers may be available. Contact the office for further details.

If the product is customised, the code is altered.
