Presumably where they grow the Philips Hue range?  I’ve certainly seen pictures of very colourful fields so you must be right.

Not wishing to start an off topic argument or debate but that differs from your "bulbs" post. As you write, that was a separate clean supply for it's intended purpose. Not the ship's main lighting.

And bulbs grow in The Netherlands!

Separate but related. As explained to me by regulars on the ship, the engineer couldn't be persuaded to run the main electrics at full voltage, citing really short service life for light bulbs. And of course it was him or his guys who'd have to keep replacing them. 

Again as relayed to me this was the case on other other vessels they'd used, but Explorer was my only first hand experience.  The relevance of the clean supply is that it also gave a consistent 240V so we were advised to use that for anything that matters. I don't know whether the ship's supply was 50 or 60Hz.
