Anyone any idea what these symbols mean?

As per title. Does anyone know what this symbol means? It’s on a IP rated outdoor light and there’s nothing in the instructions to say what it means.

Customer asked to me to take a look at a light she intends to by 10 of for her garden. This symbol was on it and I’ve never seen it before.

From this site (my emphasis):

https://telephonesuk.org.uk/wiring-info/

In more recent years NTE5 or CTE5 Lineboxes are fitted in place of master sockets, these have a removable (lower half) panel which house the terminals to connect wiring to the secondary sockets. § Terminal pins 1 and 6 may be absent on some versions of C/NTE5, but these connections are not normally used anyway. The NTE5 tends to have the same components inside as a master LJU, however later NTE5 sockets differ by not having a surge arrestor, have only pins 2, 3, 4 & 5 or 2, 3 & 5 connected, they also have a small coil in series with the ‘bell wire’ on pin 3 which acts as a filter.

So the bar-stewards don't even try any more!

For the cost of a few beers:

No idea how good, I would be tempted to open one and look. Still, if you are in London, price of one beer!
