[RFI] Florescent TUBE style, LED replacements

[Mike Schwendeman]

OK on all, Kim;

The PHILLIPS brand sounds possibly more expensive, is my only thought. 
(I have seen off-brand and therefore lower cost units from China...)

In my case, I have six double-lamp units in my shop, and I sense no FRI 
from a ballast or the lamps. (In answer to your observation of the 
ballasts being a source of RFI noise.)

I had read of the need to re-wire the fixture; In the case of your 
Phillips units, this was not needed?  If so, this is nice!
