H11 low beam vs H11 fog lamp?

I purchased what I believed to be replacement low-beam lights for my 2011 Prius. In this case, they are Alla H11-50W LED bulbs (e.g. amazon - gp - product - B011480LPA). When they arrived, the package indicated that they were fog lamps, not low beam.

But on some sites (e.g. powerbulbs - us - vehicles - cars - north-america - toyota-us - prius - 2010-2011 - car-headlight-bulbs) when you dial in H11 low-beam lights, it shows the same selection as when you dial in H11 fog lamps.

Which leads me to ask: is there a difference? Can I replace my H11 low-beam bulbs with these Alla H11 "fog lamp" bulbs?

(P.S.: I apologize for not posting the full links -- I don't yet have sufficient points do to so.)
