It seems that regardless of the number of lamps and fixtures in the room, the corners on the ceiling always remain dark. This fact did not give me rest during the renovation in one of the rooms. After a quick look at the pictures on the internet, I realized that my favorite was Peter Bristol's designer corner lamp. It was made for Established & Sons and cost a whopping $ 900!

After searching a little more, I found attempts to make a similar lamp myself, but the information was not complete, without any instructions.
I decided to take matters into my own hands and make my own corner lamp.

This lamp consists of 3 main components: a plywood triangular frame, an inexpensive lamp with a cord, and a piece of clear acrylic (plexiglass). This lamp is easy to make, although it does take some skill. You will need a hand-held power tool, and if you have a table saw, this will make everything much easier.

Ready? Let's make it!
Step 1: drawing the triangle


Draw an equilateral triangle on a piece of plywood. As you can see in the photo, I used a digital protractor, but this can be done using a regular protractor (each angle should be 60 °).
The size of the triangle must be large enough to accommodate a lamp with a base.
I have 61cm each side of the triangle.
After I drew the triangles, I drew another one with an indent in 2 cm (inner contour).
Step 2: cut along the outer office



Using the outer contour as a guide, cut a triangle out of the plywood. I made 45 ° cuts with a table saw. You can do exactly the same with a hand-held power tool, though it will take more time and the quality of the cut will suffer, you will have to modify it with a file.

Step 3: cut with a jigsaw


At this point, you need to remove the inner section of the triangle.
Use a large diameter drill bit to make the entry holes for the jigsaw. I drilled holes near each corner.
Use one of the drilled holes to start cutting. Saw as close to the pencil line as possible until you reach the next hole. Then repeat the same for the other 2 sides of the triangle.
Step 4: remove the inner corners

Step 5: mounting holes

To fix the corner lamp frame to the wall, you need to prepare the fixing holes.
I found some long screws and fitted a drill to match their diameter. The frame was fixed with the beveled side down, as it would be on the wall and drilled holes (outside).

I made a countersink so that the screw heads would hide in the frame during installation.
Step 6: clear acrylic


A piece of clear acrylic was used to hide the light bulb and diffuse the light. Why didn't I use milk acrylic, you ask? The fact is that its surface will be glossy and it will be "too" not transparent, but it's a matter of taste.
We cut a triangle out of acrylic so that it goes into the frame by 10-15mm from all sides.

The plexiglass you find will most likely be covered with a protective film, which must be removed. Don't be afraid to scratch the acrylic. In the next step, it will become clear why.
Step 7: sanding the acrylic

In order to diffuse light, transparent acrylic must be made matte. I used a sander with 120 sandpaper (you can sand it with your hands). Evenly processed plexiglass on both sides.

Finished with 180 sandpaper.
Step 8: attaching the magnets



To fix the plexiglass to the wooden frame and make it removable, because sometimes you have to change the lamp, I used 5mmx1.5mm neodymium magnets (they are much stronger than ordinary ones).
Lay the acrylic on the frame as it needs to be placed.Make small corner marks on the frame, along the side of the acrylic.
Then make a NOT through hole in the acrylic to prepare the magnet holder. The hole diameter is slightly larger than that of the magnet.

Use instant glue or epoxy to glue the magnets into place on the acrylic.
Step 9: mate


To give the magnets something to grip on, I screwed in metal flat head screws.
To do this, I put our piece of acrylic on the frame and marked the locations for the magnets on the frame. To make the plexiglass fit snugly against the frame, I made holes so that the screw head will be hidden in the frame.

Tighten the screws gently as the light frame is quite delicate.
Step 10: electrical


Before you mount the luminaire to the wall, prepare a cavity for the power cord at the back of the frame. I used a decorative fabric braid cable. It struck me as pretty cute and was cheap at a local store.
Mark where the cord will go, then carefully cut out the cavity with any tool you like.

Step 11: fixing the frame to the wall


Position the frame so that all sides are snug against the walls. The design of the luminaire is such that it fits into the corner only in a certain way, so that you will not confuse anything.

The lamp holder must also be attached to the wall as it will hold the weight of the cord. Since we have a small enclosed space in the corner on the ceiling, it is preferable to use an LED lamp rather than an incandescent lamp.
Step 12: Enjoy



With the help of magnets, acrylic will practically snap into place by itself.
When you turn on the lamp, the corners will be beautifully highlighted!
P.S. I made two of these lamps, one with a red cord and the other with a white one. I thought that white would stand out less against the background of the wall. In the end, I liked more that the red cord stands out on the wall.
