So they're not 6v ? these are 6v, whole strips but described as 6 volt: https://www.ebay.com/c/1264935641

Says 55LF561V, I'm thinking same led but those strips would be a little longer, you couldn't use those strips of course but I think vinceroger is right about them being 6 volts.

the seller are wrong the photo he put on are 3V. as OP
we look on his other offer... no V written at all.
as i wrote on my post 4 LG are 4.6V, however it measured always how much it reserve current and how much it forward to next led..

once your led tester arrives you can test a good led and see what the voltage is

May be a stupid question, but can they be tested without the tester? I.e of using battery equal to 3v, a 3v will illuminate but 6v wont?? Or am I totally missing how they work in that regard?

Just if that is the case, ive just tried with battery on a 3v LED and it illuminated, and also tried on a good one of these ones, and it doesnt. Yet it does illuminte with a 9v battery

so total 45 Leds on 2 line, if they are 6V mean each line 135 V. and this so much
if they are 3.V mean each line round 67 V and this is normal.
however you can take look on the 2 caps near to the led socket and tell the value and the working voltage... i guess they will be 150V...

There answer was on the power supply.
There are obviously 27 LEDs on the first string and 18 on the second.
A little over 6v.

diff, before 4 years i bought from aliexpress and they was 4.6 voolts. i cant find the seller any more... but now all write 3 or 6 v. and this wrong... as no one mentioned the current of sure if we use 6 it will fit to work... but the spot if the lumen are higher and if the forward current are higher so the old one will die soon.
