Greetings!
I know such lights exists. I had a StreamLight TwinTask back in the day, that offered both 365 nm and 395 nm, plus white light. But that one has long since been retired.
Currently, I only have separate 365 nm and 395 nm (that I thought was 365 nm...), like Sofirn SF16 and SF15. SF16 (365 nm) has a UV-filter, but the SF15 does not, and requires yellow UV-glasses for best visibility.
Your best bet for a quality light would be something custom. And I frequently see suggestions of "contact Hank" (Hank Wang, at Emisar) being posted for such lights. Contact email at the bottom.

I'm guessing something like a dual-channel mule (form factor / battery as desired - DW4, D4K etc.), with 365 nm on one channel and 395 nm on the other, and a UV-filter.

<p><span style="font-size: medium;">This is dual channel version, for the single channel version, please <a href="https://intl-outdoor.com/emisar-d4k-1-21700-high-power-quad-edc-led-flashlight.html">click here</a>.</span></p> <p> </p> <p><span styl

Or a triple-channel, with 365 nm + 395 nm + something hCRI. That could look something like this:
I own several Emisar lights, including a couple custom ones. So...contact Hank, and see what he can do for you.

It will likely be quite expensive though.
For cheaper options, I would suggest separate lights, like something from Convoy with 365 nm.
Due to patent restrictions, UV flashlights with filters cannot be sent to the United States!

...and since most cheap lights are 395 nm anyway, so you can get those almost anywhere.
