Ordering some parts from Clemence Virence, but what....

Flashlight Modding and DIY Parts

hi

I am working on sending a few parts from Clemence and maybe another source, to the USA.
I am looking at sending a board maybe 16mm or 20mm even for use with either Optosolis if possible set up, or E21A single LED - also a quality linear or even buck / boost driver to work well with the output of these LED’s.
where to get?.

also the Mcclicky switch has to work with the driver.

what do I need to get ordered from Virence’s Page?.

thanks.
