I'm installing a LED floodlight outside below a wooden soffit. It would

exit from its mounting surface. But I bet one of you have.

Cables must exit at the lowest point otherwise it will typically fill with water over time. One way to avoid that is to fill it with something totally waterproof, eg bitumen.

Can they enter from above?
