Run as a non-profit making organisation, Bridport Leisure Centre aims to offer a wide range of recreational facilities and activities to the people of West Dorset with a view to improving their quality of life.
The leisure centre needed to raise the lighting levels in the sports hall in order to meet the minimum lighting requirements for various sports. The existing sports hall lights emitted a decent 350 lux, but badminton regulations specified minimum average light levels of 474 lux across a court.
Like most centres our old sodium lamps were switched on at 7am and stayed on until 11pm. It wasn’t practical to turn them on and off in the sports hall because they took around five minutes to reach full brightness – and if a customer booked a court for, say, half an hour then that’s a sizeable chunk of their slot waiting for the lights to rev up.
The new lights run off half the connected load of the outgoing ones plus, as they’re ‘instant strike’ they immediately reach maximum light output.

The leisure centre therefore needed to increase the light output, but also save on the running costs of doing so, and therefore required an effective energy-efficient lighting solution.
Somar replaced the existing 48 sodium lights with an equivalent number of energy-efficient Eluma lights. The new high-bay lights increased the sports hall's average lighting level from 350 lux to almost 550 lux, as well as creating a more uniform spread of light across the area with reduced glare and scalloping.
Not only that, but the leisure centre also saw a reduction in their energy bill of almost £6,000 per year, saving 22.5 tonnes of carbon emissions annually.
