Due to the successes of the LED installed within the school, William Farr asked us to carry out a lighting survey of the external lights to see what could be done to save them energy externally.

We walked the property during daylight hours, dusk, dawn and also night times. We then discussed our findings and gave the school a number of options to consider. The school wanted to reduce the costs of lighting the school externally while maintaining adequate light levels for security and wellbeing of staff and students.

Key Targets:
• Reduction of energy usage
• Maintain safe light levels
• Fastest possible payback
• Improvement of light levels in some locations
We were able to achieve all the above targets by using a combination of our LED Flood lights, Wall lights and Bulkhead lights. Apart from being able to reduce the number of total fittings installed around the school, we also used a range of lighting controls built into the light fittings. This enabled the lights to dim down (not power off) therefore reducing the wattages used and costs of running them. As the LED already used less power, the addition of lighting controls helped to reduce the running costs even further. The school was able to maintain safe light levels at all times, while still reducing their running costs and also reducing the number of fittings at the school.

Installation was carried out during normal school operating hours with no disruption to school life
