I bought a couple of them. I was under the impression that they both lit at once, but they light every other fire. In other words, turn on the halide and the 14k lights up. the next time you turn it on the 20k will light up, and so on.
What would be the point?

No. It doesn't matter.
Better light cycle? What exactly does that mean? Photosynthetic creatures only need a photo period with enough PAR to carry out photosynthesis. Changing the color of the light is not going to make a difference. everything after 10k is all for looks anyway. All the lamps we use are full spectrum and you aren't going to get anything extra out of the 2 colors.
It's just another gimmick. Save your money.
