35 CP is insanely low for a streetlight. No wonder they have those long hovering arms to light directly above the roadway. Thats about the equivalent of a 40W tungsten light bulb, at 440 lumens., not including losses from the poor cut-off.
I have one of those, and while they look super cool and at the time the reversed cone was thought to be a clever mean to reflect the light, about ⅓ of it is wasted up to the sky because the bulb protrudes so low.
Thanks for sharing the pictures, this is super neat to see!
