DIY upgrade lights to LED in room converted to office

[goenviro]

I rent an old property so need to minimise any changes to it.
My office is a large room (6m x 7m) with a single bayonet pendant light socket which eats thru 100W bulbs and as I get older I'm finding that there is insufficient light. So I purchased some LED light panels to install over my desk and in the other half of the room and was hoping for some advice on how best to connect them to the pendant light (which is somewhat of centre in the room) with as little an impact as possible.
I did go looking to see if I could find a plug that would adapt the bayonet fitting to supply a power lead to the LED lights but had no success in that so far - any good advice would be gratefully welcomed.

Do the new fittings need an earth.

Do the new fittings need an earth.

unlikely but a very good point.
the above plugs for light fittings are NOT SUITABLE for supplying any light fitting that requires an earth.
