Kellwood's Stanford Series is an efficient, multi-purpose lighting solution for Zone 1 and Zone 2 explosive atmospheres. Available in Standard and 3hr Maintained Emergency, the Stanford Series ensures that high risk areas remain safe for personnel during regular activities or unforeseen power failures.

Its wide range of lumen packages, optics, wire-in-wire-out wiring configurations, and mounting options, makes the Stanford Series the most versatile fitting in Kellwood's LED ATEX light fittings range. It excels in small-scale specialist applications and large-scale area lighting where high average lux levels are required - providing additional cost reduction benefits though integrated emergency functionality.

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.

Details are for the standard non-dimming driver. Fixture weights exclude bracketry.

IK rating format is housing / front face; IK10 when fitted with the wire guard.

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.

Hazardous area certified product modifications are typically limited to bracketry, to keep certification. Products are supplied with OEM nameplates, codes and documentation corresponding to the certification.

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.

Contact the office for further information on driver parameters.
