I can't tell you specifically about the IPF LEDs but I have bought several different sets of LED bulbs for headlights and fog lights. There are typically two problems with LED replacement bulbs: they scatter light all over the place, and they do not have the same amount of forward light projection as halogen bulbs. I have experienced both issues with various types of bulbs I have purchased. Current LED replacement bulb technology is similar to the early days of replacement HIDs - they will continue to get better and better, but are not there yet.
The literature attached to the IPF ad says all of the correct things, but my research shows that the current "best" (that work the most like halogen bulbs) use multiple XML-2 Z-ES LEDs. I currently have a 2015 F150 that also happens to use an H11 bulb for low beams. The ebay link I am providing is of the LED bulb type that my research shows produces the best amount of light without scattering additional light all over the place and blinding oncoming drivers. These are the bulbs I am getting ready to order today.
