Perhaps I can help translate. Under the 150W M81 (HQI) shielded results you get this:

If you are looking at growing corals you want to look at the "PPFD" column which is simply another way of expressing PAR. You can see that the Icecap 6500K has the best PPFD (78), but is extremely yellow (the next column over "CCT" can simply translate to K-temp for our purposes). As you can see, it's always a trade-off between PPFD and colour as the more blue you get, the less PPFD you get, generally speaking.
