The ITT/AE Series 25s have multi-tap 120/208/240/277v ballasts if I recall correctly as well. You'll have to ask Francis. I think only some of the Series 13s, and some of the GE lights are 120v only.

Cool! I don’t know of any collectors from your country with a Series 25, let alone a FCO variant.

@fluorescent lover 40- Thats good to hear.
@Econolite03- Thanks. I know that member @Al_M has a fco model 13 from a trial installation in Brisbane.

After talking to Francis some more I have found out that he also has an m-400a2 fco! I might buy that instead. He said that he will set both aside for me until I make up my mind. If anyone wants some lights then I highly  recommend giving him a message.

I had bought a M400 NIB and it was sent to me in the original box using US post / CANADA POSTE the BOX failed mid shipping and the fixture was falling out
the fitting made it just fine but wonder if the early FAILURE of the box they took better care (OR the GE gods kept it safe)

From what I have seen Francis (Francuacr75 on ebay) packs his lights really well. Also a little update, I have decided to buy a 200w mscl from him instead because the a2 would cost about $400usd.

The weight of those mag regs are no joke. The M-400 should be multi-tap CWA. Last I saw he had two, the one for sale on eBay plus another. If the other is untouched, it might already be wired for 240v.

Isn't the one you have still listed on ebay (iirc it was made the same day). I'll hope mine is 240v (hope it works on 50hz), if not (and it's multi tap CWA) you can expect to see a post on the forum asking how to rewire it lol!

No mine is a different one in a little better shape. It came with  its original lamp but no photocell.

No need to make a separate forum post lol. If it’s wired at a voltage other than you need, all you need to do is swap the red wire from that voltage spade to the 240v one. The voltages are nicely labeled so it’s really hard to mess up. It’ll likely be wired for either 120v or 240v.

Ok great to hear, will it work on 50hz?

That I’m not sure on. Maybe @WorldwideHIDCollectorUSA or someone else can help you get a proper answer for that question.

I'll pm him.
