Picture of Concrete Lightbulb Wall Hook
This is how to make an excellent excuse for driving a lag bolt into your wall, the Concrete Lightbulb Wall Hook. Functional yet sylish, it gives a nice industrial design feel wherever you mount it.

Last winter after breaking out the serious cold weather gear, I found myself fighting the coat rack next to the front door. It was, to put it bluntly, failing miserably. Tipping over, breaking off, it was a mess. I swore before the next winter I would drive some serious hooks into the wall that would handle all my heavy overcoat needs. I just haven't seen any kickass hooks yet that I liked enough to justify making serious holes in my walls.

Cut to the last few months. As mentioned in my blog ( here, here, and here) I've been playing around, trying to make a concrete lightbulb. Why? Because I find the contrast of blending a new material like concrete in an everyday shape like a lightbulb to be a great design element. So while messing around with these guys, I realized this would be a great excuse to drive lag bolts into my wall for hooks. By embedding a lag bolt into the concrete lightbulb, I could make a wall hook that was useful enough to handle anything I wanted to hang off it. Thus this project was born.

That looks so totally awesome. Sadly, we can't buy edison light bulbs anymore. :(

Just a little late to the game......

Haven't put the bolt in yet, but you get the idea.

How much would you pay for one like this??

Let me know what you think...yes, no, maybe so?


Is that resin? Because I love the colour of it - almost honey-esque!

Yes, it is resin. To get this golden color I had to experiment with the resin:hardener ratios. I had done a clear one in the proper ratios as per manufacturers instructions, but it doesn't have nearly the same visual appeal to it.

How did you fill it while keeping the stem intact? Did you make a small hole within the stem only? And one last question, is this with the glass still on? it's an absolutely gorgeous piece.

Thank you.

No glass on there at all, solid resin. Extremely difficult to make, but will provide an Instructable shortly....

That caption on the last picture of this step threw me off. I have a tendancy of not finishing what I start, so I went to my oven and set the pre-heat to 375. Then, after setting the timer as well, I came back and finished reading the caption. I did my first ever, REAL facepalm today.

You can clean the lightbulb with salt. Pour some salt into the lightbulb and shake it around. The salt removes the white powder

I made a door handle of gypsum instead of concrete. I wanted the glass to be on the handle, but the gypsum got realy hot under the hardening, and the glass cracked. So I took the glass of and the result was better than i hoped for
Benny8025,what is gypsum? Plaster of paris? I know it's found in drywall.
Where did you buy it for your project?Thanks Elljayq
Hobby shops
serious winter gear? for me that means wearing socks with my sandals...loved the intructable...nice work
Here in sa
Winter entails :
Sleeveless t shirts
short pants
and crocs
here in des moines Iowa we have gotten about a foot of snow in one night... everything closed down except for the des moines public school district (dmps). they never close for anything..... also I do not like the cold at all!!!!! I lived I tucson Arizona before Iowa and I am used to highs of 110 degrees F.........
Sadly, that's what my winter hase been like this year--and I live in Colorado. It's a sorry state of affairs when I can wear a short sleeve shirt in Febuary. >_<
sorry to hear that...I am looking at 75 degree days but 40 degree nights..could use some rain...drive the tourists away and make beach parking easier..Perhaps you will get the snow you need

I need to make 1...or 3....dozen. :0)

these would make great stocking stuffers for Christmas!! Birthday presents! I can think of a million & one reasons for giving as gifts!

TY for sharing. :0)

When separating the glass from the concrete hanger, I was thinking, about why you can not use a rag to wrap the hanger/bub in?

It will stop the glass from flying, contain the glass in 1 area/spot/whatever, and when finished, just toss the rag into the trash.

Granted, you still have minute particles of glass to deal with, but as you said, a shop brush should take care of that.

Nice Idea!!!

In one side I've been thinking on how to recycle soiled light bulbs but I didn't find it any easy myself.

In the other I love to hang my stuff on doors to get them more availableand keep a roomier wardrobe, but this kind of hungers aren't so easy to find, most of them fall down to the floor within the first week.

Good luck selling them!!

This looked like fun so I gave it a try. unfortunately I could only find hydraulic cement which sets in about 5 minutes. to add to my woes, I got the piece all put together (bolt not straight but, all else looked good for a first try) but then dropped it the following day. the bulb came off easily but it is !missing the shininess of the one in the 'ible. Someone suggested using polishing compound which helped some but I think I'll end painting this one to cover the flaws.

After painting, I intent to drill through a porcelain fixture and insert the cast into it as if it were a real light. I wonder how many folks it'll fool! perhaps I should use space under the porcelain fixture as a safe. talk about mixing content.

For a first try not too bad though. I've now got some mortar mix and am anxious to give my next one a try.

Does anyone know how to safely dismantle a cfl? I think one of those would be fun to try as a cast.

happy casting

Instead of a toothbrush & soapy water table salt will take that white residue right out just put a spoon full of salt in the light bulb hold ur thumb over the end & shake it it will clear it right up!

the way we go through lightbulbs around here, I won't have to buy any...

Very nicely written, very educational,....can't wait to make a few(dozen) myself. :P

Absolutely great! This is one of the finest exponents of creative thinking. Reminds me on Picasso abstract paintings: so simple, everybody can do it. But only good old Pablo actually could.

one question, how do i make it?

This is a fantastic idea actually! My husband and I are trying to go with a very contemporary, modern style in our home. Having concrete lightbulbs for coat hangers would go perfectly with our theme. I will have to check first, but I think that my husband will love them too!

I wonder if a different, less messy (no broken glass each time) way to do this would be to perhaps make a 2-part urethane mold of a lightbulb. You get the same accuracy, and can pull many parts from the mold over time. Also, there are good concrete mixes that will cure in under an hour with very nice results.

This was my first instructables that I watched here,back in the days. Now I found it!

blending of concrete in an everyday shape like a light-bulb is genius. congrats..

I hope you don't mind...I placed a link to your site on my site... http://cehalles.wordpress.com/2014/03/13/my-simple-creations/...I needed good instructions for hollowing out the light bulb and urs are very clear...thanks

That is a pretty awesome idea. I love to learn about little things like this that really improve on a lot of the things you would just buy in the store without thinking about it. I'll have to try that.

I was reading another instructable on concrete balls and remembered this one. Anyway I saw a post about using expansive cement and thought if it doesn't expand so much it trashes the metal, doubtful, it might make this a lot easier as it breaks the glass away for you. It has a nice looking finish too.

noahspurrier says: "I make cement spheres the same way! I use pure expansive cement (AKA expansion cement) with no aggregate, which creates a different look. It has no aggregate and no voids. The expansive cement has one advantage in that it actually cracks itself out of the glass mold."
