yes, rejected ;-) My aim was to unify the tagging of > these objects, since they all generate light.

What would be other values for this new key? Checked it, actually "light" is taken: http://taginfo.openstreetmap.org/keys/light#values but "light_type" seems available (zero usage as of taginfo). There is 337 of "security:light_type" which supports the idea that "light_type" is about the type of lightning device http://taginfo.openstreetmap.org/keys/security%3Alight_type and also the "lamp_type"s support this reading: http://taginfo.openstreetmap.org/keys/lamp_type (they do not refer to the fixture). cheers, Martin
