What distinguishes a 415nm UV LED from a 425nm UV LED in terms of light output and application?

UV LED technology has been a game-changer in various industries, from curing adhesives and inks to sterilizing water and air. With the advancement of UV LED technology, we now have access to different wavelengths of UV light, each with its own unique characteristics and applications. In this article, we will explore the differences between a 415nm UV LED and a 425nm UV LED in terms of light output and application.

Understanding UV LED Wavelengths

UV light is divided into different wavelength categories, including UVA, UVB, and UVC. Within the UVA category, we find UV LEDs ranging from 365nm to 420nm. For many applications, UVA LEDs in the 400-420nm range are the preferred choice due to their effectiveness in curing and sterilization processes. A 415nm UV LED and a 425nm UV LED fall within this range, and understanding their differences is crucial for selecting the right UV LED for specific applications.
