Cost savings of 15% or more can be achieved by ensuring that the lights, their fittings and controls are well maintained.
- Help maximise daylight
Clean windows and skylights to allow the maximum daylight to enter the space. Remember dirt can build up on the inside as well as the outside of the windows so both sides should be cleaned.
- Have a maintenance schedule
Produce a checklist of activities to allow the lighting system to be thoroughly and consistently checked at frequent intervals. Keep a record of light levels in each space and any issues that may need addressing. By comparing records you can determine the best time to implement a cleaning programme.
- Maintenance should include:
- cleaning light fittings (especially plastic diffusers)
- replacing old lamps
- checking controls are in working order (ensure timers are correctly set, occupancy sensors are clean etc)
Replace dim or failing lights
Replace blackened, flickering, dim or failed fluorescent tubes with tri-phosphor coated ones for a more natural, brighter light for the whole life of the tube. Carry out regular replacement of all lights mounted at height. This ensures that all lights in an area are the same age and reduces the risk of failure, which could have health and safety implications.
Remove unwanted or unnecessary lighting
Consider removing some fluorescent tubes from multiple tube fittings in over-lit areas. This should be done with care to ensure there is still sufficient light to satisfy health and safety requirements.
Remove unnecessary lights where building use or layout has changed. Check and disconnect redundant lights such as those obscured by equipment or shelving. Controls should be located in the same room as lighting where possible.
