Great. I have bought a Masterseal SFCU and it works ok.
Using the black pond rubber cable left over from a TLC order.

With that length of wall, several lower-powered lights and PIRs
might provide better coverage. Most types (but not all) if you
interlink them with 4-core cable (live, switched live, neutral,
earth) in parallel, any PIR sensing movement will trigger all
the lights.

Noted, and thanks.
