We have a wall made from railway sleepers, alongside a gravel drive. We want to install mains fed LED bollard lights on top of the sleepers and I'm trying to figure out the best looking solution and I'd appreciate any helpful advice.
The sleepers are 6" high x 9" deep and the wall is two sleepers high, about 30 m long. Each bottom sleeper is anchored with two, 2 foot spikes into the hardcore base of the drive and the top sleepers are screwed on. It's at least as sturdy as an equivalent size brick wall - some idiot drove into it shortly after it was built and wedged the car on top of the wall. The bottom sleeper didn't move and the top one only moved an inch.
There will be 6 lights, each 9w.
One suggestion was to use 1.5mm SWA fixed with cleats to the side of the sleepers, terminated into galvanised 20mm conduit boxes at each lighting position (6A MCB and 30 mA RCD from a nearby DB). The back of the boxes then drilled to take a flex gland, with a corresponding clearance hole drilled into the sleeper with flex feeding the light. I guess we could do the same with steel conduit instead of SWA. Burying the SWA is going to be difficult without digging up the drive and we still need a neat way to terminate and feed the lights.
Any advice or alternatives?
