What do you suggest for specifying the kind illuminant of highway=street_lamp. I'd like to differ between sodium and mercury vapor lamps. Personally I suggest illuminant=Na for sodium, illuminant=Hg or illuminant=W for tungsten bulbs.

It seems that people are already making a distinction between gas lamps, fluorescent, and incandescent lamps via the lamp_type=* tag. Maybe it is worth further refining this. If you are interested in street lamp tagging, also see lamp_mount=*.

Note that OpenStreetMap has a strong tradition of human-readable tagging, so most people would probably prefer if you spell out tag values rather than using abbreviations from the table of elements.

There is also the tag [lit_by_gaslight][1] has several hundred uses with a strong cluster in the Dusseldorf area. It would be nice to have the ability to describe the characteristics of the lighting in a more universal way without having to map individual lamp posts.

I think the one who is interested in this will understand chemical symbols.

Also consider looking at a new proposed feature lamp. Under that scheme you would map it as lamp:light=mercury. That proposal also has many other options for adding detail, like the shape of the light produced, power source, color, and more. And if you think there's something wrong with the scheme, please add your comments to the talk page.

There already is a lit=yes on the sport tags, perhaps you could do lit=yes (mercury|sodium|incandescent|arc|big_death_star_laser_thingy)

I think this is similar to a tree tag, where you only note very specific lamps that may be historical or significant in nature, for a highway or sports field the lit tag seems to be a better use.

An example of a significant lamp would a moonlight tower in Austin Texas http://en.wikipedia.org/wiki/Moonlight_tower
