Basic "Cambria" care?

[KittyKat]

I have an orchid which was sold under "Cambria" which I have read is a commercial name for Oncidiums so hopefully this is the right place to ask about it.

Firstly I would like to confirm that it is an Oncidium: when it was flowering (recently finished), it had two flower stalks with only flowers on it, spaced in the same way normal Phal flowers are, with no branches off the main stalk. Is this possible with Oncidiums? I have previously only seen ones with multiple branches off the main stalk which had the flowers on them. The leaves grow in the same manner and look almost identical to those of Oncidium "Sweet Sugar".

Secondly if it is an Oncidium, what are the basic care instructions? Water and light requirements would be good.

And finally, is there a good photo resource I can look at to try and ID this orchid? Unfortunately I do not have any photos of it flowering.
