Quite interesting. However, the Wood`s lamp has become a less useful diagnostic tool of late. Up until the 60`s the typical fungal species often fluoresced under UV light. But, today the common causes (eg. dermatophytes, yeasts, etc) for tinea infections in the Western hemisphere are predominantly non-fluorescent.
Still good for detecting microsporum canis, pityriasis versicolor and, of course, the corynebacterium associated with erythrasma which fluoresces a pretty coral-pink under UV light.
How dark does the room have to be to see the pretty coral pink lights? Sounds saucy but is a serious question as I was considering getting a Wood's light but was wondering whether it would be worth it!
