365 nm for Strongest Fluorescence
In addition to 365 nm UV lights having the advantage of not emitting violet light, many objects will fluoresce strongest at 365 nm, as evidenced by absorption spectrum measurements.
The result is that 365 nm light may be better suited for applications where stronger fluorescence effects are desired. Coupled with the advantage of having a lower amount of visible, violet light emitted, 365 nm light can considered an optimal choice where performance is of paramount importance.
