When will Eevee evolve into Espeon

It doesn't evolve on a certain lvl....you have to get it happiness up to a certain lvl at daytime for it to evolve into it....i recommend fighting in the area near the daycare with the eevee....but be careful....you must not let it get its health into the red or you cant lose....dont ever put it in your pc....and you must take good care of it....like groomings from the haircut guys (the younger one is better....possibility of 10 happines added)

The max happiness you can get it 220....but it doesnt take nearly that much for it to evolve into that....if you want a umbreon....do the some thing,but at night time.
