THE SMART TRICK OF LED WALL DC THAT NOBODY IS DISCUSSING

With AlGaN and AlGaInN, even shorter wavelengths are achievable. Close to-UV emitters at wavelengths about 360–395 nm are already low cost and sometimes encountered, one example is, as black mild lamp replacements for inspection of anti-counterfeiting UV watermarks in files and financial institution notes, and for UV curing.
