Connecting the Lighting

• 1). Your fiber optic lighting kit should come with an illuminator to power the lights. Test the illuminator and cables to make sure everything works before installing.
  
  
• 2). Find a place where the illuminator can be stored and connected to an outlet.
  
  
• 3). Make sure you have enough cable to run from the illuminator to your glass blocks. Cover up the electrical cables for a nice clean look. This could be done simply by running them along the trim between the floor and the wall, or even through the wall.
  
  

Installing the Blocks

• 1). When purchasing your blocks, make sure you buy spacers that will allow you to install fiber optic cable. Be sure to buy enough spacers and blocks to complete the project.
  
  
• 2). Lay out your first row of blocks and attach the spacers. Do not silicone or mortar anything yet.
  
  
• 3). Lay the cable on top of the blocks and spacers and hold it in place with clear electrical tape. Some cables loop around to the next layer. Other cables are capped with tissue paper at each end. Refer to the instructions on your fiber optic lighting kit to be sure.
  
  
• 4). Lay the next row of blocks.
  
  
• 5). Silicone or mortar the gaps between blocks. Remember to use a clear silicone compound; one that dries dark will stop the light from shining through. Wipe off the excess silicone with a damp rag.
