BTW - I have a Hell Fighter with the SF cig lighter connector, etc...and it has the option to hook up TWO batteries as well.
So, I've been using it with the 12 v set-up, but, the directions indicate it will also be able to use 24 v.
Does anyone one know if the HF would be brighter with 24 v than it would be on 12 v, or is it just able to use both equally, etc?
There so many versions of the HF out there right now that input voltage may allow for in series hookup HOWEVER the dual battery set-up typically is in parallel, so 24V may be pushing it a bit.
The ballast regulates the power to the bulb so input voltage as no effect on lumens.
