Deutsch > Englisch Technik Technik (allgemein) Lighting

I'm translating a description of a lighting product and this word has cropped up.

I can't find the specific product I'm translating, but other examples of the phrase in-context can be found here: http://elektrokomponenten.ch/media/files/k_k-licht-12-312.pd...

If it helps, the light product this word has appeared in is also called Downunder - that appears to be a common theme.

I'm rather stuck here so any help would be greatly appreciated!
