B&M plays the lux only racket. But their lights are poor lumens/lux
ratio. Lux only says the intensity at the brightest point anywhere
in the beam. No mention if this is STVZO or not. Best guess is that
it isn't. My STVZO working concept is more efficient than any STVZO
beam currently on the market. It would need 18 watts for 100lux
STVZO, and even that would probably not be able to stay under 2 lux
on the horizon. ~65 lux at ~9 watts making 650+ lumens is about the
ceiling for a single LED STVZO compliant light.


Nah, they just have a more intricate beam shape than ol' flood light Barry.
