Installing led light bars

Howdy all,
I am installing some led light bars into our high top van. I wish I understood electrical nomenclature more but can some Einstein educate me on these led bars as I want to make certain I’m not causing a greater power load than the previous, incandescent fixtures.
On the box it states:
Input voltage: DC12V-85V (why the range?)
Power: 8W
LED qty: 120pcs

Which of these do I need to pay attention to and why?
Any help?


I can’t tell you why the range, but 12v falls within it, so that’s good. 8 watts is under 1 amp @ 12v, so you’re good there too.
