If you must know, Phillips is not considered one of the top brands in
the U.S.


Yeah, they must be trolls.

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.

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.

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.
