URBAN Linear | Transforming Working Conditions | RAYTEC Case Study

RAYTEC SPZ-WL84

Transforming working conditions

The existing installation Raytec predominantly used 2x58W T8 fluorescent fittings, mounted 4.1m above the factory floor, combined with emergency twin spot style fittings to provide backup illumination in the event of mains power being lost.

With many of the old fluorescent tubes degrading and beginning to ‘yellow’, frequent maintenance and relamping had been required to keep the illumination to an acceptable level. Despite this ongoing maintenance, illumination uniformity was poor with several dark spots around the factory floor. As a result, there was a need for additional task lighting at bench level to assist the operators.

Outcome of using URBAN Linear Lighting

However with the supply of fluorescent tubes being banned from September 2023, the need to upgrade the lighting system to LED technology was more pressing than ever.

Additionally another issue was the layout of the luminaires. Having been first installed by a previous occupier of the building, the luminaires did not align with the racking located at one side of the factory floor which is used to store parts used by operators during production. So this meant illumination between the racking was below the desired levels and also caused an obstruction which limited the height of the racking.

WL84 Generation Linear

These SPZ-WL84 Light fittings are globally certified to Zone 2 offering long life LED Technology.

This range is manufactured by Raytec and distributed by Thorne and Derrick and are designed for new hazardous area installations or to retrofit existing fluorescent installations which require high performance, high reliability and white light illumination in potentially explosive atmospheres.

Secondly, Raytec’s URBAN Linear luminaires are specifically designed for Industrial applications, were used to replace the existing fluorescent fittings on a 1-for-1 basis. While the new installation used the same number of fittings, the more powerful URBAN luminaires meant smaller, more efficient units could be installed in place of the larger 2x58W (5ft) fluorescents.

A mix of URBAN Linear WL84 (36W, 2ft) and WL168 (72W, 4ft) luminaires were deployed across the installation.

In conclusion, the URBAN LED luminaires significantly improved the quality of illumination, increasing average lux levels from 300lx to 400lx with improved uniformity. The extent of the upgrade means the reliance on task lighting is significantly reduced.
