First, not much of an electronics guy, more somewhat experienced with basic DC stuff.....
So, my cabin is off-grid, and I run the LED inside lights off a bank of 7.2ah 12v batteries (because I have access to them, and...because....free).
I'm not at the cabin, and unfortunately I don't have any more info on the device than what I've given...hoping maybe someone knowledgeable has played around with one of these and is familiar with if the voltage would be regulated somehow or not...

Looking at this on google, I count 60 LEDs. They would take up to 1.2 amps, if they are driven independently or 0.6 amps if in series pairs. To this must be added a small current for the solar sensing. At this rather high current I would recommend using a regulator to get from 12V down to 6V.
To save you the trouble of wiring up a regulator chip you might like to consider this: https://www.bitsbox.co.uk/index.php?main_page=product_info&cPath=140_171&products_id=3202 or similar.
This has the advantage of high efficiency so will help keep the load on your cabin batteries as low as possible.
