Question about Lifx Z Color & White

I just asked myself the same question today. It is not clear from the item description (or I simply did not find the reference).

But since the price is significantly lower than the 2m package, I thought there must be a relevant difference.

After some research on the internet, I came to the conclusion that the 1m should only be bought as an extension to the 2m "starter kit". On the LIFX homepage the products are better/clearer named: "Z LED Strip - 2m Starter Kit" and "Z LED Strip Extension - 1m Pack".

@Digitec: Can you improve the "naming" or the description?
