Custom LED Spiral Staircase Lighting

I needed a lighting solution for my spiral staircase. After looking at various options (such as direct lighting from above or below) I decided to create my own lighting using some cheap components and a bit of time.

I’ll show how I designed and built my lighting rig. Hopefully I can help other people avoid some of the issues I’ve found and improve my project and others.

Steps

Step #1:

  • Pictured here is the center support for the staircase. All wires and components (except the LEDs themselves) are housed here.
  • Next we can see one of the LED strips that I used. They're sold in long pieces that can be cut down to about 2.5in pieces containing 3 lights and a resistor.
  • Lastly, the circuit board that I made to provide power to the lights. Not my best work but it serves its purpose.
  • Thankfully, my soldering skills have improved a great deal since I started the project.

  • The first step was drilling holes into the center support. The holes allow you to draw the wire through and keep things hidden.
  • I used three 3in self-tapping screws to serve as a platform for the battery and circuit board (and later the dimmer switch). This allowed me to run wire unobstructed and still provide support for the components.
  • I accidentally used the wrong gauge wire initially. It was quite a bummer when smoke started pouring out of the support. Luckily, steel pipe is harder to burn through than the cheap wire I was using. The real shame was that I spent around 2 hours running it all and had to pull it out.
  • Be careful when placing holes in any sort of support structure. You can weaken it substantially if you aren't careful.

  • I took the cap that had been covering the top of the stairs and sanded around the edges to make it easy to turn. I use this to control the dimmer switch for the lights. It is connected to a 12v DC dimmer that I ordered for about $18.
  • The dimmer rests on top of the 12v UPS battery that is powering the whole thing. The battery lasts for around 6 days before needing to be recharged. I think eventually I'll use a small power supply that will power the lights as well as charge the battery. That way the lights will still work during power outages.
  • I made a simple stencil of an arrow to show which way to turn the cap. I think it serves its purpose well enough but could probably be clearer.

  • Here you can see the completed system. The cap is turned clockwise to brighten the lights, counter-clockwise to dim them.
  • By powering the system with a battery there is no need for a wallwart or other wires running to the stairs. This keeps things tidy and also allows for light during power outages. As mentioned earlier, I believe it will be prudent to add a more permanent power source to avoid wear on the battery.

  • Any comments or ideas are welcome. I don't believe that I did everything in the best manner possible but, all in all, I think the finished product is well worth the effort.
  • The total cost of supplies (not including solder, hot glue, etc.) was around $70; $36 for the lights (which amounts to 20 of the 3-LED strips, not all of which were used), $18 for the dimmer, and $16 for two 100ft spools of 20-gauge wire.

Conclusion

A great way to light a spiral staircase.
