12v xhp70 in Convoy c8

Will the DD fet driver from RMM handle 12v? I'm thinking c8 with 2 extension tubes and xhp70 12volt

You’ve found extension tubes for the Convoy C8?

I think the main issue is the zener having the appropriate power rating. So… depends on what you’re working with. The design in general would work, yes. Would need to calculate the ADC values for LVP as well.

Each light by convoy has its own thread type something has to fit.
