Security Lighting can significantly reduce the risk of an intrusion. It is important, however, that the lighting is carefully designed and installed, as careless lighting can create glare which obstructs vision. Below are some tips on ensuring lighting is both efficient and effective:
- Lights should not illuminate above 80 degrees from the nadir (the point directly below the light). This is often easily accomplished with Full Cutoff lighting.
- Lighting does not need to be as bright as possible, as this can create glare and unnecessary wear and tear on the bulb. Generally only 0.5 watts per square metre is needed, but this might need to be increased or reduced depending on the environment.
- Using several smaller lamps instead of a couple of powerful ones will reduce glare, provide more even lighting, and ensure that if one lamp malfunctions your security will not be compromised.
- Check that the electric meter box is locked in order to prevent vandalism.
- In the same vein as using several lamps, multiple circuits can prevent an accidental or malicious short or cut causing that could cause a system malfunction.
