As far as anti-collision it must converge at a point with in 1200 feet in front and behind the aircraft. This is not addressed. If it does , it does, that's cool, but to get 400 candles you would think that Nav light reflectors (front and back) would block the intensity somewhat. Also with out a focus lens to direct and amplify the strobe bulb light in the horizontal plane (mostly from +/- 10 degrees from the horizontal), I don't see how it can do it, but in this document they point out it is up to the builder to meet the requirment, which is a fair and true statement.
I am not saying it does not make it, but it does not look like it from inspection you will get the proper coverage fwd and aft. Look a Whelen, it is protruding strobe with a lens to intensify the light in the proper horizontal plane / direction.
As far as the NAV lights I don?t know. I think the words are good, love the reflector (which is somewhat like whelen's and BFgoodrich's approach for their LED nav lights, but all 28V). I have no reason to doubt the logic, but I think testing would be the only way to verify meeting the requirements. However it is up to the builder to prove it not the manufacture (of non TSO'ed) equipment.
Lights (anti-collision and nav) and transponders are two items I know of, off the top of my head, that must meet TSO'ed requirements, even for a kit plane. They don't have to be TSO'ed only meet the requirements. In theory you could be asked to prove it meet the requirement. This applies to any non TSO'ed light system, but doubt that would ever happen.
