Yes, as dougall mentioned, this is not T5 HO, so that means I have little to compare it with. But if it helps, here is a link to a comparison chart from a Canadian supplier that may help one of you sort this out. From the data here, I would say this is less than T5 but probably better than T8. Wisteria should be OK, once we know the GH issue which could have been the issue before, as it was with me.Here they are even though they don't look to have the 6700k:
