All they're saying is they tested the lights at 3SM (or 4SM in this case), and they passed the test. And yes, someone has tested these, @pilotinstitute did: . They aren't saying it's tested by the FAA and FAA documentation is included.Again it is semantics...this is what it says
FAA compliant testing documents in the package to assist with night waivers
there is no such thing as FAA compliant testing documents in this regard ...and it does not indicate testing was done by a third party that I noticed...it looks like it is self certified ...a bit misleading...has anyone else seen thees in flight and able to see them beyond a quarter mile or so? I do agree that they are probably the brightest I have seen...but I don't think they are really visible at 4 miles away as they are claiming...not even the 3 that is required
Also, I've tested one of the less bright FHT strobes and it passed my 3SM test with no problem.
