Industrial and commercial lighting



The lighting at Renault Trucks Commercials’ Reading logistics base used to be so poor that technicians often needed to use head torches to work properly. This – and much beside – has now changed and been vastly improved through the transition to a new site-wide and emergency lighting LED scheme By Liz Hudson and Alan Robson


ighting is an essential ingredient in all commercial buildings and facilities. As a business, whether or not you get this right will affect virtually every aspect of your commercial operation, from energy expenditure through to emissions, from working comfort through to evacuation procedures. Even the distances at which employees can perceive yellow warning marks and oncoming hazards are, of course, affected by light. Following a number of successful retrofit and commercial LED upgrades and conversions, including for Volvo’s facility in Motherwell (‘Scottish Premiership’, Lighting Journal February 2019, vol 84, no 2), Carbon Reduction Technology

(CRT) was recently commissioned to carry out an LED upgrade for Renault Trucks Commercials’ logistics facility in Reading. The facility is a busy logistics base for the company, covering repairs, maintenance and MOTs for many HGV and LCV (light commercial vehicle) vehicles in the south east of England. The facility includes extensive high-bay spaces for working with the vehicles, plus low-bay parts storage, administration and customer interaction areas.


The original lights in the high-bay areas were 400w energy-intensive highpressure sodiums, outputting 150-200

lumens, augmented by natural light ingress via five large roller shutters set into an exterior wall. However, technicians were still finding light levels too low and on overcast days where ambient light from outside was minimal were often using head torches for tasks that would not normally have required additional illumination. The project brief for the main maintenance area and MOT bay was therefore to increase output lumens at floor level and, crucially, to achieve a much more uniform spread of illumination. The objectives were to achieve increased comfort, safety and visual range for the technicians on the facility floor and a reduction in energy consumption and emissions to contribute
