Question Hello, I’m in the property management business and want to identify mold growth. From my research it seems that 365-380nM Longwave UV light is best, and the smaller the wavelength the better. I’ve seen your application matrix, but it doesn’t specifically call out mold detection.

Can you make a recommendation? Ideally it’d have enough power to cover larger areas (10sf?) but also be usable in tight spaces (is it possible to be too bright or powerful)? Are fluorescent backlights better for this application?

Answer
If the mold you are trying to identify is similar as alfatoxin-producing mold, the 365nm UV LED should be best option because the absorbance spectra of aflatoxins show peaks of around 362nm.
We make 365nm UV LED in different wattage, from 3W (Slim penlight) to 2000W (used for UV ink curing for the printing industry).

I would recommend you try the Slim-UV 365 penlight first. This is Good for tight spaces.

for larger areas, the 120 degree coverage SR25 light will work. We don’t keep this item in stock, it usually takes 2-3 weeks for us to make one.

Please let me know if you have questions.
