Dialight’s DuroSite® LED Lighting Fixtures
RAF Odiham is a front line support helicopter base just south of London and known in recent times as the home of the Chinook force in the UK. The base has many facilities for service personnel and dependents alike and a distinguished history going back to 1925.

The Challenge
Having started life as a multi-use barn, RAF Odiham’s 35-year old Building 140 H3 needed a radical lighting upgrade to turn it into a suitable facility for stripping down and rebuilding helicopters. The former barn was fitted 20 years ago with forty 400W SON high bays which were producing so little light that task lighting was necessary. Many of them failed every year and annual maintenance was running in excess of £1500. Targets for the lighting upgrade included increasing the lux from 100 to 500 at work level as well as delivering energy savings and reducing carbon emissions, all from a turnkey lighting solution with an acceptable payback period.

The Solution
Working with energy saving specialists the Dodd Group, two solutions were evaluated as replacements for the entire lighting installation. It was calculated that 192 x 400W SONs or 132 x 170W LED high bays would be required in order to achieve the 500 lux target alone.
Specialist in LED technology Dialight was chosen for its proven track record of high volume applications in commercial and industrial sectors and its constant high end production of LED lighting manufactured in the UK. As each LED fitting also carried a 5-year warranty and
could be expected to last 10-15 years, maintenance would also become a thing of the past.


The Result
The Dodd Group completed the installation in only five weeks from start date, delivering the turnkey solution promised. By opting for Dialight’s 170W LED high bays energy use in the 24/7 facility is over 70% lower than it would have been if the SONs had been installed
instead. Unlike SONs the LED fittings can be switched off without re-strike delays, so the installation now features four workable lighting zones and one central walkway. These can be operated to suit users during the 24 hour shifts and this flexibility allows even more
energy savings and associated reduction in carbon emissions. When combined with the maintenance savings, these efficiencies have allowed RAF Odiham to achieve a payback period of only 1.2 years when comparing this investment in LED technology with the
alternative solution of energy-hungry and limited lifespan SONs

Matt Clarke of the Dodd Group commented: “The lighting has made a dramatic difference to the works space, enabling the RAF to efficiently work on detailed engine systems and maintenance tasks without supplementary task lighting. There is virtually no difference from night to day in the hangar now and this helps with the 24 hour shifts utilising the building and improves staff morale. H3 at Odiham is a benchmark for sustainability as well as value for money.”
