A comparison of lighting technologies used for perimeter security applications

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
Lumens/Watt  100–190 80–140 65–115 25–150
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
Price  $$$ $$ $$


As the table shows, LED-based lighting offers the best combination of factors for perimeter security applications.
