Job done!
The new LED bulb had L and N markings on two of the four pins, so I simply connected the corresponding two existing wires from the lamp fitting to the L and N supply after removing the electronic ballast and terminated the two unused wires.
Tidied the wires up a bit before putting...
After a fair bit of Googling, I came across the following diagram for the G24Q fitting, which seems to reflect what you are saying:
I guess rather than working from the ballast and trying to figure out which is live and neutral, I can take 2 of the 4 wires from one side of the G24Q fitting...
The email response I got from support at Any-Lamps was:
"These lamps CAN replace the existing CFL lamp but you have to ensure that it is compatible with your installation (ballast). You can refer to the compatibility list under downloads. If your ballast make and model is not listed, then most...
It's quite a large light fitting, so lots of space/air around the lamp. I thought LED bulbs ran cool, which is one of the reasons they are so efficient? I would be surprised if a LED replacement bulb was running hotter than the CFL bulb, so heat shouldn't be an issue.
Any-Lamp have now responded regarding my question about simply replacing a CFL lamp with their LED lamp in my fitting. And the answer is only if the LED is compatible with the ballast and after further investigation, the electronic ballast in the fitting does not appear to be on any...
I confess, when I read that part of the description stating "... Without Starter ballasts only" I had assumed it was saying the bulb didn't need a ballast to work, so I had assumed the electronic ballast in the fitting would need to be removed. I agree, the "Installing this lamp.." section does...
The bulb I linked to earlier would be a perfect fit for the existing lamp fitting, providing the ballast was removed as it is similar in size to the existing G24q-3 CFL bulb.

Yes, I was planning to use one of those "weird" LED replacement bulbs, which would then require me to simply remove the electronic ballast. The other "small white plastic box" in the fitting is simply a plastic protector and has a cable connector within it. I assume this gives the light an IP...
Yes, one of my concerns about converting the fitting to use a 240v bulb is the existing bulb holder. Is that specifically designed, especially the 4 cables, to only expect a lower voltage? I described the larger device (Landlite model EB-28) as a transformer, but I guess this is the ballast and...
Thanks for the link, but we really don't want to change the light fitting. Our current fitting is much nicer than those shown in the link and as ericmark says, I would prefer to have a changeable bulb, rather than a throw-away fitting.
While looking for a replacement bulb, I found the following, which I initially thought might be a simple plug in replacement, but the product data sheet indicates it requires 220-240V, so that got me thinking about modifying the fitting:
