  That sounds to me like the Philips AmbientLED.  There are two higher
wattages 11 and 16, with much higher lumens/watt mid-upper 30's IIRC.
And this is with 3100 K color and CRI of 85.  Available at Home Depot
for that matter.

  Meanwhile, please find me a 7 watt 120V incandescent achieving much
more than 6.5 lumens/watt with life expectancy 3,000 hours or more, let
alone the 40,000 hours for Philips LED lightbulbs.  For that matter,
anyone find me even an off-the-shelf available 15 watt 120V incandescent
lasting 2500 hours or more producing 155 lumens.
