Collect hidden evidence such as fingerprints, liquids, and other traces during on-site surveys that are not visible to the naked eye but fluoresce under UV light.
Easily judge the cleanliness of your home, hotel rooms, or other environments by revealing mold, stains, and other biological residues that emit bright fluorescence under UV light.
Regularly check the skin condition of pets to detect potential fungal infections (ringworm) which fluoresce. Also effective for detecting pet urine stains on carpets or furniture, as cat urine will show a fluorescent reaction.
The powerful 1300 mW UV light source is suitable for curing UV-sensitive resins, making it useful for various craft and repair applications.
