Lumens comparisons mean nothing if the output goes in the wrong direction.

The holy grail for any aftermarket headlamp is D.O.T. approval of the beam pattern. So far there are many claims but no actual approvals for any aftermarket emitter in a Ford spec parabolic reflector behind a McKee patent spec "Twolite" lens.

When that occurs as well as product that has both a realistic color temperature in the 3400-4300K range that matches well with human spectral response at night, combined with a true calculated color rendering index not less than 85 we will have a winner.
Mechanical engineering 101: If you put an adjustment knob, screw, bolt, or tolerance specs on something, some people will immediately fiddle with it. If you mark it DO NOT TOUCH everyone will mess with it.
