Top 4 security lighting technologies

Last week’s Security Digest explored the top four lighting factors – Color Rendering Index (CRI), lumens per Watt (lm/W), color temperature, and lamp life – that can affect the performance and efficiency of perimeter security systems.
This week, the Security Digest compares four lighting technologies – Low Pressure Sodium (LPS), High Pressure Sodium (HPS), Metal Halide (MH) and Light Emitting Diode (LED) – to determine which has the best combination of these factors. Each has its own advantages and disadvantages, but when it comes to perimeter security applications, there is one that shines brighter than the rest!
The following table compares the technologies against the four top lighting factors (as well as three other factors that contribute to efficiency – full light spectrum, warm up/cool down time and price). Red indicates poor performance, yellow indicates average performance, and green indicates best performance.
|Color Rendering Index||0||20–60||60–90||70–95|
|Color Temperature||1,800||2,100||3,000 – 20,000||Wide Spectrum|
|Lamp life (hours)||18,000||24,000||20,000||50,000–100,000|
|Full light spectrum||√||√√||√√||√√√|
|Warm up / Cool down (mins)||5–10 / 15||5–15 / 15||5–15 / 15||Instant|
As the table shows, LED-based lighting offers the best combination of factors for perimeter security applications.
