LED Lighting Enhances Security

It is also important to note that security lighting acts as a psychological deterrent to criminals, because it increases the chance a crime will be witnessed. And if a crime does occur, it can be assessed after the fact through recorded video. Ask any camera manufacturer and you will get the same answer: higher illumination at the scene produces better results.

However, as security integrators know, not all light is created equal when viewed through a camera or when calculating strike time — which is the time it takes for a light to properly illuminate a scene once it powers up. The Color Rendition Index (CRI) also has to be considered — a measure of the ability of a light source to accurately reproduce color. In this context, accuracy is considered in relation to natural light, and is measured in a range from zero to 100, the value for daylight.

For security, Light Emitting Diode (LED) lights are the best option for parking garages across a number of factors, including CRI ratings, long life and actual price. Another important consideration is the even distribution of illumination: ideally, the light across a scene should maintain light-to-dark ratios of 4:1 for security applications.
