The new Lightsave LED Magnetic Tube fixtures are expected to provide annual energy savings of more than 48,117 kWh, which translates to more than £481.75 in monthly cost savings or £5,781 each year compared to the old lighting. Additional savings are found through diminished maintenance needs, calculated at nearly £312 annually, due to the rated 50,000-hour life of the LLS fixtures compared to a rated 20,000-hour life of T8 Florescent Tubes.


Williams Motor Company Walton was established in Liverpool in 1954 and moved to Scotland Road in the 1970’s and in 1976 switched to the BMW and Citroën franchises and began trading as the Williams Motor Company, later becoming Williams Liverpool.

A first car showroom was opened in 1960 on Deansgate, which sold new and used cars under the Rootes franchise, in 1970 Williams acquired the BMW agency in Manchester, around this time the Williams Bodyshop moved from Trafford Street to Hadfield Street, where it remains today.

Mr Antony Bamford Body Shop Manager agreed that the Body Shop lighting level was not sufficient enough for BMW quality requirements, lighting levels with the traditional T8 fluorescents tubes gave a reading of 426 Lux with the minimum BMW required being 800 Lmns therefore a solution was needed.


As part of its commitment to reduce energy consumption and its direct carbon footprint, BMW Williams has made the leap from traditional lighting to the latest LED technology. The Auto Body Shop chose Lightsave LED Magnetic Tubes because of the 135 Lmns Pr Wat output and cost base.

Replacing the old 8ft florescent T8 Tube with Lightsave LED 8ft Magnetic Tubes together with a 5yr warranty and a life expectancy of 50,000hrs has achieved a 1127 Lmns level in the trim shop with an energy saving of £5,781 per yr. Maintenance has been reduced and at the same time the light quality is greatly improved in the Body Shop.

Anthony Bamford the Body shop manager commissioned the work. Jason Scott, Senior Energy Manager at Lightsave LED carried out the energy audit which concluded the need for LED Lighting for required lighting levels set by BMW.

The light levels averaged from 426 Lux to 478 Lux, BMW Insisted on achieving a minimum 800 Lmns pr watt and now the achievement is 1127 Lumins which is far better than expected.
