Huge Decorative Domed Street Light

I’m not sure what to call this unique lamp. It has the look and feel of carbon arc street lamp but has decorative elements not normally found on a utilitarian street lamp. I’m guessing it may have been a street lamp but for a private estate. In any case the lamp is very impressive. Inside the dome is a hand-blown clear glass egg shaped globe. We have newly wired the fixture and now takes 3 bulbs… 24″ x 32″… $2800
