This lamp is made from a traffic cone, some old OSB, and a couple of threaded rods. The latex rubber cone actually diffuses and transmits light surprisingly well, but I punched a pattern into it with a soldering iron to let some more light out. The base part is optional, but again, it lets a lot more light out if the cone can be elevated a little bit. A toggle switch mounted in the bottom of an aluminum can sits on top like a nose cone on a rocket.

Cones are available on eBay for cheap, but the shipping can be a bit much. Orphan cones are a dime a dozen in cities, but often too dirty and messed up to use. Please don't steal them from active job sites, because they are safety equipment for someone. Other good places to check are auto salvage yards and the county/municipal dump, because that's where the local government takes their bulk waste.

My cone is 28" tall and 14-3/4" square at the base, and weighed about eight pounds before the lamp parts were added. They come in all different sizes, and you could even make a desktop one out a of a little tiny cone. I used a 75-watt equivalent compact fluorescent. A brighter fixture could eliminate the need for the holes. Do not use conventional bulbs; they get hot enough to damage/burn/melt the cone if there's nowhere for the heat to escape.

I apologize if some of the pictures are a little blurry, it's very dark in my basement.

Step 1: Base Plate

As I mentioned in the introduction, the whole base plate part is optional -- you can just sit the cone on the ground as it normally does. However, by elevating it, the switch comes up to a good ergonomic height, and by drilling holes in the base plate, you get a cool pattern of light on the floor.

I measured a 14-3/4" square on some scrap 1/2" OSB and cut it out with a circular saw. OSB isn't an ideal material, but it was free. It is hard to cut and prone to bad chipping. MDF or plywood would work just as well. I found the center and traced a circle from an ice cream tub, then drilled holes along concentric rings, using smaller drill bits as I worked out to the edge. Make sure the middle hole is big enough to pass the plug through. Punch four corner holes for the threaded rods.

The last picture shows the underside of the board, post-holes. OSB is awfully chippy, but you'll get the same problem with regular plywood, to a lesser extent. Just peel them up and sand, seal/paint onto them, make the rough side inside the lamp to hide it.

I put two coats of polyurethane on it, but stain, paint, or seal as you desire.
You could shoot it with a shotgun and the holes would probably turn out very smooth, eliminating the fumes and the scraping with the pocket knife, and the black burned plastic.<br>Cool ible.
Talk about having flash backs&lt; i made one in 1977 with a cone the General Telephone man left behind, It was awsome because it said GENTEL from top to bottom. Made for a good party light in the 70's..thanks for the memories.
Hmmm... Where did you get a traffic cone? :P This is cool! Imma rate it 4!
You can get them in VLC programs.Not VNC.
I <3 VLC!!! lmao:P
they sell them at hardware stores
Lol, ok thanks!<br/><br/>But notice how I said &quot;Where did <em><strong>YOU</strong></em> get a traffic cone?&quot;<br/>
My friend and I found one while kayaking in a little lake over here.
Nice instructable.
If you put tape on the back side before you drill the holes.....it will stop the wood from splitting and chipping....then just peel off the tape! :D
Looks great, Nice work
really cool! Do you think light will travel trough ticker cones ?
Nice! I want to make a mini version of this.
make a mini one using leds =D<br/>that'd be cool, having it on your desk and all :p<br/>
Nice instructable, as a suggestion you may want to consider adding a materiasl/tools/ safety step. Nice job on your project.
Sweet man... so doing this! Man, after I've done all the crazy shizz I have in mind my room's gonna be crezzeh. Props and five stars.
Wow, an idea I've had but not posted, rated and featured, I'm impressed with this one, I never had the afterthought of elevating the cone. As a suggestion to get more light output switch to a CFL 'daylight bulb' they put out more light and in a wider spectrum, they travel through stuff like this really well.
