How much voltage using stock?

Can someone please tell me how much power the hi/low stock headlights use when on? I would like to replace them with LED just to save on used power. I have my light bar that I will use for most of my nighttime driving. I figure by pulling the stock headlights and replacing with LED’s, on the rare occasion I may use the headlights, the swap to LED would save a ton on power for something else like the winch or something along those lines. Could also use some suggestions on which reliable LED headlight bulbs to buy.
This swap would be on my 2014 Grizz 700 EPS.
Thanks in advance.
