justjazz Lumacom have three different versions of their technology - Lumapanel, Lumavideo and Lumapole.
Lumavideo is a low margin product which was used in the Barcelona sign - this product been nearly dropped because of the competition and smaller margin.
Lumapanel, which has been used in Perth and Moscow, and more recently NY and Turkey is the higher margin technology - most large corporations that are contemplating using Lumacom signs wouldn't have had an opportunity to view the signs in Moscow and Perth, hence the reason for going ahead with the 4TS location.
Lumapole never really been spoken about - maybe limited uses for these "signs".
Megagroup was also going bankrupt and having problems with their agencies in different European countries, hence the reason that the Barcelona sign never reached it's full revenue potential - Megagroup weren't interested.
Hope that goes someway to explaining your query JustJazz.
