This was a mildly ambitious diagram that I've pretty much finished now. I've done a PFI for my home town, Hemel.
The areas shaded white will be lit predominantly by WRTL Libras running 36W fluorescent tubes.
The areas shaded orange will be lit mainly by Tamcourts burning 55W SOX.
As for the lines:
White - WRTL Libra, post-top, 36W PL-L
Yellow - WRTL Iris, post-top, 35W SOX
Orange - Tamlite Tamcourt, side entry, 55W SOX
Red - Philips SRS201 (MA90), large shoe, 90W SOX
The peach lines are SON but the lantern and column will vary depending on the application. Where it is shown on main vehicular routes, Urbis Opalos burning 100W lamps will be used, though for areas such as the Old Town more classical styles such as the Tamlite Citrine may be used.
