I don't know about US, but in EU they must have PFC correction, and
the ones I've seen do, because the PFC circuit makes for a neat way
to ignite the tube first time.
PS: The fact that you get about 10-20% more light (due to the high
frequency drive) and longer lifetime (no burnouts) are good reasons
to upgrade. Here in .dk it's often cheaper to buy a new armature
with tube, than a spare tube...

Never attribute to malice what can adequately be explained by incompetence.
