Update. Nearly the entire house is LED now, Mostly Cree, except for the 4 foot tubes in the kitchen and garage. They are Hyperikon bought from Amazon, and they are the kind that run off of 120 volts directly so you have to remove the ballasts in your old fluorescent fixtures. That is no big deal. There is also a couple of no name fixtures and a screw in "batwing" type of LED bulb 10,000 watt equivalent downstairs in the craft room. man is that thing bright. No failures with any of them except the original old Cree bulb number 1 in the lamp upstairs that became flakey as noted back in 2016. So no failures, No RFI, just lots of light so far.
