Step 11 Mount stoplight

If you haven't already, figure out which of the components can reasonably fit inside your light and decide which ones will be external.  In the case of this light, we decided to keep the 9 volt power supply external (up in the ceiling) and the other stuff inside the light.  This makes troubleshooting easier since all the custom components can be accessed simply by opening up the light and swinging the lamp out on a hinge.

To keep parts from rattling around in the light, you should secure them by whatever means make sense for your light.  I used a hot glue gun to glue the backs of the project boxes to the insides of the chassis.

If the light is just going to sit on your desk, you are pretty much done.

There are a number of options for mounting the light.  There are holes on the top and bottom where pipes can be attached and wires routed.  We had considered mounting the light on a pole, but decided instead to buy a wall mounting kit.  This kit consisted of two pipes with right angle fittings that mated to the light, and brackets on the other end to mount to the wall.

I wasn't present when a colleague mounted the light, but my understanding is that the steps were something like this:

1. Attach pipes to light.
2. Figure out where the light is going to hang, and where the brackets will subsequently touch the wall.
3. Attach brackets to wall using heavy duty drywall anchors.
4. Drill hole in drywall through the hole in the middle of the top bracket.
5. Attach light to brackets.
6. Fish power wires though top pipe and into wall.
7. Feed ethernet cable through top pipe into light.
8. Plug in power cords into power strip mounted in ceiling.
