If you must know, Phillips is not considered one of the top brands in
the U.S.
Yeah, they must be trolls.
You said it, not me.

Oh no? ROFLMAO! Who do you think first developed LED bulbs? Here's a
hint: it wasn't Phillips.
Hint:
The Energy Independence and Security Act (EISA) of 2007 authorized the
Department of Energy (DOE) to establish the Bright Tomorrow Lighting
Prize competition, known as the "L Prize".
On 3 August 2011, DOE awarded the prize in the 60 W replacement category
to a Philips' LED lamp after 18 months of extensive testing.
Yes, but they did not develop the LED bulb. You obviously are not
reading, and arguing for argument's sake.

No, at the time neither had an advantage. You need to read up on the
"war" between Tesla and Edison.
At the time there was no such thing as an effient DC-DC converter but
transformers did exist; that was a HUGE advantage.
Which had nothing to do with the war between Tesla and Edison. You
should read about the history before proving your ignorance.

We have only digital TV here, also. Been that way for over 5 years.
Nope, we still have legacy analog in many places and that was the
reason the FCC denied the petition to establish a 4M amateur band
in the US.
Nope. There is no analog TV in the United States. But those
frequencies ARE being used by digital TV stations - as the FCC said in
its denial of the petition.
Once again you prove your ignorance.
