Our Five Top Tips On Lighting
Our Five Top Tips On Lighting
1. Only install a light if you really need to!
Question whether a light really is needed at all before installing one. If you still think lighting is needed, then only install enough light for the job and turn it off when not in use.
2. Use properly fitted fully shielded light fittings.
The proper term for these lights is full flat glass cut off lights which means that no glass is visible below the light cover. Mount it horizontally to ensure no light escapes above the horizontal and that only the area intended is illuminated.
3. Use movement sensors.
Movement sensors should be used wherever possible to ensure lights are only on when needed. Lights that turn on as someone approaches are much more effective at scaring burglars away.
4. Time switches are a good alternative.
If a sensor is not appropriate, consider using a time switch on your light. It should be set to turn lighting on and off only during periods when lighting will be used or beneficial. Don’t leave them on all night. You’re not only wasting energy but your money too!
5. White light sources should be used.
The best type of lighting emits a clear ‘white’ light. These are the only lights that allow us to see colour and shapes properly. They can also be more efficient than the orange/pink coloured lights.
