Street lights: gas AND electric, therefore ca. 1910[edit]
In front of the park green there is a typical gas lantern with 4 glasses, Not higher than 3.5 meter, that the daily manual enlighting and service can be done with a 2.5-m-ladder, easily to be carried by one man.
Behind the green rises a upside-down-J shaped 9 m high mast carrying an electric light, more likely a carbon arc lamp than a tungsten incandescent bulb. This lamp can be let down by a rope for servicing.
About in 1910 the lighting in a school building in Graz has been changed from gas (from 5 or 10 years earlier) to electric. Possibly in Odessa street lighting made the change at the same time.
In front of the dark Personal monument is a higher double gas lantern, the whole photo shows about 6. I count the same number of these high electric light masts. (At highest resolution + zoom in.)
