Venture Provide an Energy Saving Solution at Bedford Hospital

Venture Lighting Europe has supplied its Part Night ballasts and White-Lux Plus lamps for the refurbishment of car park and warehouse areas at Bedford Hospital, part of the Bedford Hospital NHS Trust.
The Venture system, recommended by Century Lighting, has been designed to provide a high level of flexibility which includes the dimming of light levels during quiet times, resulting in a far more energy efficient lighting scheme.
Bedford Hospital is a 403-bed acute district general hospital providing first class healthcare services to more than 270,000 people living predominantly in North and Mid Bedfordshire. These services are delivered mainly from one site in the centre of Bedford, and include a 24-hour accident and emergency department, acute medicine, maternity, paediatrics, older peoples' services and a comprehensive range of surgical specialities. The brief was to replace the existing High Pressure Sodium lighting at the hospital’s main staff and visitors car parks in Britannia Road with the aim of achieving a better quality of light.
Various options were considered, including LEDs but on further investigation it was proven that this would not be a practical solution. Following discussions, Redditch based Century Lighting suggested replacing the 250W SON lamps with 150W metal halide in the main car parks. Trials confirmed that the metal halide source would indeed offer excellent light levels and provide the right choice for the project. Century also suggested using Venture’s Part Night electronic control gear so that the lamps could be programmed to dim in quiet times such as midnight to 6.00am.
Venture’s White-Lux Plus 70W and 150W lamps were used throughout the project along with the replacement of some of the older fittings, which were used with Century’s “Brisbane” and “Park” luminaires. Venture’s Part Night ballasts were programmed to ensure adequate light levels were maintained at times when vehicle and pedestrian traffic is at its height, such as visitor times and staff shift changeover times.
Programming for Part Night can be carried out post-installation via the existing mains cable, eliminating the need for additional wiring or expensive communication packages. Each ballast can also be individually addressable to maximise the range of configurations available and lighting points can be controlled individually or in zones and re-programmed at any time to reflect changes in lighting requirements.
Brian Randall, Project Manager at Bedford Hospital commented “I was quite sceptical about using a metal halide source at first however, following Century’s advice, I have to admit that the light levels are excellent and we are very pleased with the result. The annual savings for the scheme is calculated at £2.5k per annum – this includes the savings by reducing lamp wattages and changing to electronic control gear. We are now in the process of costing up the next phase to upgrade utilising the same system.”
