"I can not for the life of me figure out how (stepping up the voltage) reduces the power consumption"

Marketing!


No can get mo' dan you got.
'cause,
Pound for pound, a watt's a watt.

For efficacy and lumens per watt,
I'm no Johnny on da spot.
Lotta specs bewilder me.
Fo' dat kine, betta shake Knna's tree.

He'll prove dat da bumblebees no can fly.
If ya wanna launch one anyway, den I'm yer guy
(sorry Knna, could not resist)

Mo' seriously.
I could not be more tickled to see you toss your hat inna ring.
I can offer pragmatic advice if ya hit a snag, but mostly I'd just like to lurk and watch how you tackle this.

Aloha,
Weeze
