I'm just gonna back this guys up.space... those aren't 100w and 150w cfls... they're more than likely closer to 23w and 42w... those bigger numbers are just their equivelants if they were incandescents...
the smaller ones are daylight and are a better spectrum for vegging (though i think they're only like 4500k, there are some that are 6000k) and the bigger ones look to be warmer 2700k ones
is it 5500K?I'm just gonna back this guys up.
I've seen/owned those bulbs, the nvision bulbs are 5500k, and the big ones are surely 2700k. The only 6400k I've seen in store are at walmart.
