In recent years, UV-C radiation has become an essential tool for disinfection, particularly in healthcare, water purification, and air quality management. However, not all UV-C radiation sources are created equal. Traditional mercury-based UV-C lamps and newer UV-C LEDs differ in several crucial ways that impact safety, environmental impact, and efficiency.
Here’s a closer look at why UV-C LEDs are becoming the preferred choice for disinfection applications worldwide.
In the field of UV-C disinfection, two main radiation sources dominate: conventional mercury lamps and newer UV-C LEDs. While both can effectively disinfect surfaces, water, and air, they differ significantly in performance, environmental impact, and efficiency. Here’s a breakdown of these differences and why UV-C LEDs are rapidly becoming the preferred choice.
Key differences between UV-C mercury lamps and UV-C LEDs
Let's dive into a few differences between UV-C mercury lamps and UV-C LEDs
1. Lifespan
Mercury lamps: typically last between 100 and 10,000 hours.
UV-C LEDs: have an increasing lifespan, the current UV-C LED generation has a L70 lifetime of 10,000 hours.
Product implication: UV-C LEDs provide a longer-lasting solution with lower operational expenses as a result of reduced lamp replacement cycles.
2. Warm-up time
Mercury lamps: require up to 15 minutes to reach full brightness and effectiveness. Short activation cycles (0 - 100secs) reduce the lifetime of the lamps significantly, while radiation output during the warm-up period is slowly increasing to nominal values.
UV-C LEDs: turn on instantaneously, achieving full power immediately.
Product implication: the immediate activation of UV-C LEDs supports an extended replacement cycle, making them ideal for applications requiring frequent on/off cycling.
3. Heat and cooling requirements
Mercury lamps: generate significant heat during operation, often requiring additional cooling systems like fans to prevent overheating.
UV-C LEDs: produce minimal heat, eliminating the need for active cooling systems.
Product implication: with no need for cooling, UV-C LEDs operate 100% silently and do not require fans, resulting in lower maintenance needs and longer-lasting performance. This makes them ideal for noise-sensitive environments and helps reduce overall operational costs.
