Anything to cap a fluorescent tube socket
- Thread starter Yanni

As far as I am concerned, you can just leave them as they are - since they are designed that way.
As the fittings have power factor correction capacitors built in with no tubes they will be running a leading power factor. A factory normally pays for VA not watts so you will be paying for your empty fittings.
You can tell that, how?
Well we all know how much I slag winston1 off for being wrong so often
On this occasion I can only say it is extremely likely he is correct. In fact I'll go further and say I don't recall a fluo fiting without a PF correction capacitor wired across the mains other than some special orders where bulk PF correction was performed.
My suggestion is to leave the tubes in but switch off/disconnect unwanted fittings.
The "mains' as in "input" supply.
However, if the device is not switched "ON" the PF capacitors will not be connected across the "mains".
As you wrote :- "switch off/disconnect unwanted fittings"
Surely only if they are 'switched on'?
As we have seen from other posts from the OP:
Emergency lights location
I’m having emergency lights installed in factory. 38m long with columns in the middle. What is the best location for the lights. The ceiling has many arches. Can I have them installed at the bottom of the metal Trunking where most of the cable run through the middle of the floor ? Any...

If the lamps have HF ballasts no option must turn them off, leaving without tubes or even leaving with faulty tubes can damage the ballasts as I found to my cost. With wire wound not really a problem, but seems unlikely today to find wire wound.
I had this problem a factory where it needed scaffold to access lights, so would wait until ¼ failed, then swap all be them working or not, but when we moved to HF, found 50% those which had failed needed new ballasts fitting, so had to re-think policy and change the tubes as they failed. They will auto shut down for a short time, but if left get damaged.

Open one up.
No you often being a cyber bully.
Fitzgerald fittings often didn’t (cheap DIY), but certainly any quality brands always did.
Better than giving incorrect information...
However:
I've fitted Fitzgerald units and to be fair not found them to be any different to other brands except the universal units they manufacture (fluo/LED) don't contain PF correction or for that matter any form of ballast or choke so presumably not an inductive load.
I thought Fitzgerald went under a few years back?
Has someone purchase the name & started to manufacture again?

There is still a web site https://www.powerlitefitz.co.uk/ however as said running HF fluorescent fittings without tubes in them risks damaging the ballast, some fluorescent fittings have a built in fuse, removing the fuse seems to be best way to decommission without removing the fitting. But I see no reply from @Yanni seems we have frightened him off.
