This panned out into 159 episodes in the Dragonball Anime, and 291 episodes in the DBZ Anime. DBGT was spun off from this by some other writers and lasted only 64 episodes. DBGT was also meant to be shorter, but because of delays with the release of the DBGT video game, it was extended with the Super 17 saga. Unbelievably enough, there's a scientific explanation for Saiyan to Oozaru transformation. Thus, their moons are made up of similar stuff as well.
Moonlight is little more than sunlight reflected off a moon.
17,000,000 units of the Buruz wave is the minimum needed to trigger a transformation. This is a fairly bright light, so a full moon is the only thing that will suffice. The 'Fake Moonlight' trick is quite a misnomer as it only emits the necessary Buruz wavelength. A hormone flows in the blood which gives rise to and maintains the transformed state. The gland for this hormone just happens to be in the holy Saiyan tail.
