OK. I stand corrected, at least in part.
What we know now, though, is that we don't really know anything about total lumen output (horsepower) of Sylvania's offerings, but we have the extra glare and scatter of "blue/white" light to make us think we have more (a la "butt dyno").
Regardless, total lumen output is still the only measure that matters. Not "color temperature."
And the Philips Premiums still put out more.
Light vs. hype. You choose.
