Just about to change the last Halogen external floodlights to LED, to facilitate this I bought a couple of IP68 straight waterproof three pole connectors from TLC: IP68 Straight Waterproof Connector 3 Pole - https://www.tlc-direct.co.uk/Products/WPQC1.html to my surprise they are Wago type lever connections inside, not screw terminals I was expecting, very neat.
