Calculations are based on a mid-selection gas boiler and regular installation costs – according to your prerequisite.
With AlGaN and AlGaInN, even shorter wavelengths are achievable. Near-UV emitters at wavelengths around 360–395 nm are currently affordable and infrequently encountered, by way of example, as black light-weight lamp replacements for inspection of anti-counterfeiting UV watermarks in paperwork and financial institution notes, and for UV curing. Substantially more expensive, shorter-wavelength diodes are commercially accessible for wavelengths right down to 240 nm.
