Scott Safety cuts lighting consumption

Published: 13 November 2012 - Joe Bush

Scott Safety, a provider of life safety protection products and services, is reducing its energy consumption with the help of lighting manufacturer MHA Lighting.

As a consequence Scott Safety, a Tyco Company, is set to cut its lighting energy consumption by 81% at its Skelmersdale site.

With thousands of people depending on Scott Safety products to protect them in high risk environments, it was imperative that light output, light quality and uniformity were high quality so as to aid precision working.

With its low energy luminaires and ability to design bespoke precision lighting solutions, MHA Lighting was chosen to replace all the existing T5 fluorescent fittings in both the warehouse and on the shop floor.

After trialling various fittings to find the optimal light colour, MHA Lighting’s TiLites were chosen that supplied 80CRI and 4000 kelvin colour temperature. This combination can significantly enhance the working environment which will also aid precision working and contribute to a greater feeling of well-being amongst the staff.

The project saw a total of 281 MHA lighting LED luminaires with 23 sensors installed - this included 113 award winning High Bay TiLite 70 fitting (82W including ballast) and nine TiLite 30/120 (45W including ballast) installed above the shop floor and 46 Oval High Bay 150W fittings in the warehouse.

This reduced annual lighting energy consumption from 263,907kWh (annual cost of £26,391) to just 51,730kWh. Annual energy bills have therefore been reduced to just £5,173.

Through its low energy LED Luminaires, MHA Lighting was also able to achieve a reduction in CO2 production of 84% in the shop floor area and 64% for the warehouse. This equates to product lifetime CO2 savings of 2,003 tonnes (115 tonnes per year).

Pete Osborne, production engineering and facilities manager for Scott Safety, said, “Lighting is a significant part of us achieving our carbon footprint reduction goals.

“When we set out on this project we wanted to find solutions that not only improved light quality but also significantly reduced our energy consumption.

“MHA Lighting has been able to offer a solution that ticks these boxes. Not only are we seeing real cost savings on our energy bills but the light colour, output and uniformity is superb and our staff are benefiting from the improved lighting.

“With the integration of various intelligent controls we have made further reductions on our energy usage and given that the units will run maintenance-free for seven years we will also decrease our maintenance costs.

“Overall we are delighted with the installation and are now looking at further projects aimed at improving our office lighting.”

At current operating hours the fittings offer a useful lifetime of 16 and 25 years for the shop floor and warehouse respectively. Throughout their life they require no maintenance, saving Scott Safety a further £51,905 in maintenance costs during product lifetime.

This takes overall lifetime savings for this project to £419,953.

Tom Harrison, MHA Lighting MD, said, “Scott Safety carries out important precision assembly operations, such that the quality of the light - in terms of light uniformity and colour, as well as high levels of light output - is crucial.

“MHA Lighting ran a series of trials at Scott Safety before the customer selected the light colour that they felt provided the ideal working environment for their employees.

“Another key factor of this installation was the integration of intelligent controls.

“Because of the high quality sky lights in the factory we were able to utilise ambient daylight sensors so that during daylight hours the fittings will burn at a fraction of their total output thus maximising energy savings further. PIR sensors were also installed in the warehouse.

“It has been a pleasure to work alongside Pete on this project. Their commitment to reducing energy consumption at the site is impressive and the team at MHA Lighting are delighted to be playing our part in helping them achieve their environmental goals.”
