Does any one know what kind of par the Ushio 20K's have? I was thinking of changing from 14K Hammy's to the Helio's 20k because they still have decent PPFD for a 20K and they should be a little more blue than the Hammy's. But if the Ushio's have good PPFD and aren't dim I would probably get them instead.
