I picked up a 600w version from a buddy who said that he did switch it too the 400w setting in the beginning few weeks. I immediately thought was not a good idea. After looking at the vivosun website, im under the impression that if both the ballast and bulbs are 600w, changing the lumens is not an issue and is designed to do that. Can anyone comment on this? The ballast clearly indicates it dimmable.
