Concrete Light Bulb Lamp

​One of the classes Steph took at the Haven DIY Conference was learning how to cast with concrete. The class, sponsored by Quikrete, was taught by blogger, Ben of Home-Made Modern, the guru of all things concrete! Steph made this fun concrete hand in the class (see below).

Once home, we decided to put into practice what she had learned. Steph also took a concrete class on the DIY website Instructables.com. 

We decided to make a light bulb lamp utilizing an Edison bulb we got at Ikea and a silicone bundt pan I found at a yard sale for .25!
  • We couldn't find the concrete we wanted locally, so we went with the basic Quikrete Ready-to-Use Concrete Mix with the intention of making it work by sifting out the larger rocks. At $5 for an 80lb bag, the price can’t be beat!
  • Note: mix concrete outside as it’s dusty and dirty. It left a thin layer of concrete dust where we worked and beyond inside my house.

Materials/Tools:
  • Quikrete Concrete Mix
  • Water
  • Trowel (we got the smallest trowel available and it worked very well to mix up small batches of concrete)
  • Disposable plastic bowls (we used one to mix in, and a couple to sift into and another to hold the rocks we sifted out)
  • Sifter (we used an old basket fryer)
  • Drop cloth/plastic garbage bags
  • Plastic wrap
  • Paper towel cardboard tube
  • Hot glue (optional)
  • X-acto knife​
  • Something to scoop concrete with (we used a tuna can after our plastic cup fell apart)
  • Sander or other tool that vibrates
  • Cooking spray like Pam
  • Gloves/face mask
  • Silicone bundt pan
  • Bean bag 
  • Large diameter drinking straw 
  • Lamp Cord
  • Lamp socket
  • Self-stick felt
  • Edison LED bulb

Prepare the silicone mold. Place the cardboard tube over the center. Cut a hole near the edge of the mold and slide the straw through to the middle. Cut a hole in the cardboard tube.

Hot glue into place if needed. We hot glued the straw into place on the outside of the mold as the mold started to tear. (The straw is gong to serve as a tunnel in which the cord will be run through the concrete.)

Wearing gloves and face mask, use the sifter to sift out the rocks. Place the amount of concrete you want to use in a clean plastic bowl—we used about six cups at a time.

Add just enough water to make a stiff batter like consistency—kind of like brownies. Don’t add too much water. Use the trowel to mix.

Spray the inside of the bundt pan with cooking spray. This will help the mold slip right off when the concrete is cured. 
  • We placed a bean bag underneath the center of the pan to keep the middle part from collapsing and flattering out. It worked well.
  • Using the trowel, start filling the mold, patting it down as you go. Be careful around the straw so it stays on place. Mix up additional concrete as needed and continue to fill.

Using the sander without sandpaper or multi-tool, place it on the edge of the mold to help move air bubbles to the surface.

Cover the bowl with plastic wrap and leave undisturbed for 20 hours.

At the end of 20 hours, remove the cardboard tube, and the concrete from the mold.

Use 60 grit sandpaper to remove any rough edges. Clean up the straw ends so the outside part is flush with the side of the concrete.

Wire the lamp socket.

Thread the cord through the straw from the outside. Remove the bottom from the socket and thread this onto the cord.

Identify the hot and neutral wires and wire the socket—the ribbed half of the wire is the neutral. This connects to the silver screw in the socket and the smooth half of the cord is the hot wire and connects to the brass wire. Do some research if you’re new to wiring a socket. It’s not hard but you need to be sure to connect the wires correctly.

Replace the bottom of the socket—put the socket into the center of the concrete base.

We found the socket would not stand up straight in the center so we added some stick-on felt to the bottom of the socket to add some thickness—this worked well—we also added a piece of felt to the bottom to keep it from scratching the surface it's placed on. You could also use electrical tape to add thickness to the outside of the socket.

Screw in the bulb and you are done! This is a perfect lamp for Steph's nightstand. The weight makes sure she will not accidentally knock over the light in the dark.

Concrete is one of those materials that just sparks creativity. I find myself looking at objects as sources of molds in which to cast concrete—silicone baking pans, silicone ice cube trays, glass globes and vases, even the insert that came with my Harry & David peaches look like a mold! 

What material sparks your creativity? What would you make from concrete? What do you think would make a great mold?

What a great idea!
This would also make a great gift.

I also love the tree beside the lamp.
Where can I get one?
