The problem is that they may put out the lumen but the focal point is different so no matter what LED setup you have when using a reflector housing they can NOT reproduce a standard bulb. And if the focal point is not the same you will NOT get a well focused beam. And your NOT going to get 350 feet... If you look at my VLED bulbs those put out 3500 lumen. They are GREAT for seeing deer on the sides of the road and for looking through the fog in front of me. But it is deceiving how far they actually throw and with the "hot spots" they don't light up the full road in front of you.
