I think I understood someone here to say awhile back that the replacement LED lamps that used the existing standard ballast in a fixture didn't save any energy because the current draw for the ballast was the same. I tried to find some of like that but all I have seen recently say "for replacement in fixtures with electronic ballasts". What would be the difference in these 3 methods?REGGIE, just buy led bulbs that bypass the ballast, they are 110v, throw away the ballst, red,blue go to black and yellow goes to white. 6000k cri at least 45w, that is a touch over 100w flourescent.
