I have alongside some normal square pin 13 amp sockets some 5 amp round

The round sockets were installed maybe late 90s in an 80s house by the
previous owners, I was advised by an electrician that this was an old
format of being able to switch on table lamps from a light switch rather
than the wall socket.

modern, not old

I have no idea which circuit they are on ie socket ring or lighting ring.

presumably lighting

Now my question, I have recently purchased a 20 watt LED external
floodlight that comes with a 13 amp square plug, now I need to increase
the length of the cable and was looking to put a 5amp round plug on it
at the same time so I can use from the unused round pin socket.
Will this be safe to do so? With regard to Amps/wattage etc
Secondly I may purchase another 10 watt floodlamp so would it be ok to
run both from that 5 amp socket?

20w @240v = 0.08A. 5A 240v = 1.2kW, so well within its ability

Someone else can moan about RCDs, but it shuld be fine.
