Introduction: DIY Indoor Outdoor Concrete Lamp 2

Glass Challenge 2017

Grand Prize in the
Glass Challenge 2017

Every since I made the first set of concrete lamps, I have been asked to produce another. This time it had to be easier to make, had to be larger, and with the option of placing it outdoors. After brainstorming here is the attempt of improvement. Check out the video for more details.

What you will need

1. Led String Light - http://amzn.to/2koQPfq

2. Felts Sheet - http://amzn.to/2lJowbY

3. Cement 4. Large vase ( I used a 24in tall x 7in)

5. Drill bits - http://amzn.to/2kwnv1P

6. Random tree branch

7. Spray paint http://amzn.to/2kwbZDE

9. Metal flashing http://amzn.to/2hvS7TZ

Step 1: Making the Storage for Led Controller

I took a piece of foam from a shipping package. Cut it to create a cylinder. I closed it by taping the side. then cut out a circle to close off one end. A paper cup would work as well.

Step 2: Creating the Concrete Form

I used a piece metal flashing to create the concrete form.

First I marked the metal flashing for the bottom of the form, I made this 5 inches tall. Next, I marked 2 inches above the first line. At this point, you will have two parallel line.

Now wrap the metal flashing around the vase. Close the flashing by taping the loose end. By the way, I'm using a large vase that's 24 inches tall by 7 inches. You can find that at your local craft store.

Next, I took two 1 inch rubber seal and follow the line going around the interior. Following the line I drew out. I did this twice which gave me a two-inch path around the interior of the flashing. This part will shrink the interior, which will make the concrete fit right over.

Step 3: Mixing the Concrete

Take a piece of aluminum foil, place it down on a flat surface. Then I trace the vase and then the foam cup as shown. Use hot glue to secure the cup then the flashing to the marking.

Mix concrete and pour it in the form.

After a few days remove the flashing and rubber seal. The bottom was smooth so I only had to sand the top.

Step 4: Using a Tree Branch

I took a tree branch and sprayed it with black paint. Allow enough time to dry. Depending on the size of tree branch you chose, use the appropriate size masonry bit. I use a 1/2 inch bit to drill down to the bottom into the foam cup. Test that everything fits nicely.

Step 5: Install the Light

Drill a hole in the lower part of the concrete form for the power end to pass through. Next, use hot glue to hold the plug in place.

Pass the Led String light power end down through top then connect to the power cable.

Step 6: Adding the Lights

Feed a few feet of the led into the vase. Then place the branch in the vase and feed more led as you proceed.

Now sit the vase on top of the concrete. I placed a felts pad on the bottom to protect any surface.

Step 7: The Finish

I love the way this lamp came out. The LED String Lights works extremely well. I was able to get this lamp to work approximately 50 feet away. Hope you have a blast when you make yours.

Such a great design. It popped up in the feed around NYE this year. Great to see it getting attention!

Question : I've thought about making a bunch of these and using around our pool for ambience. The solar option would be ideal, as would a non-glass enclosure. Anyone know anywhere to get an acrylic or plastic vase like this? I've scoured for them in the past and not found anything that seems right (most aren't tall enough if they're a good width or are too skinny if they're tall enough). Thanks!

You won't really find suitable acrylic vases in this size. If you are looking to make these for around your pool, you could use acrylic display stands and modify them to your needs. I warn you, they are not cheap. If you're crafty you could potentially make something similar to one of these stands cheaper by using plexiglass or acrylic sheets cut to size. It'd be a lot more work but I think the end result would be what you'd want. If you do make them, please upload some pictures. I'd like to see the end product. Good luck & HNY.
