Which class to use for user specific configured Batten luminaire

Hello

We are producing costumer specific linear LED systems (see also https://smarterion.shop/#/configurator/shop/1) . So I'm not sure if I should always use class EC000109 wich has some good matching features but it is designed for a fixed length (Lumen per luminaire, not per meter for example). On the other side, there ist class EC002706 which matches good at Lumen/m, Power/m but isn't really for luminaires with an Aluminium profile just for the LED strip itself I think. What would you recommend?

ETIM classification is designed for 'off the shelve' products and not for configurable products. In the latter case you can use ETIM 'reversed' to allow the customer to give a standardized specification of what he needs. 

Looking at your products, EC000986 - Electrical unit for light-line system might be a good choice, but will still not give you options like lumen per meter. That is again since ETIM is not developed for configurable products.
