Love the IKEA TERTIAL, but hate the harsh glare? We fixed it.

The IKEA TERTIAL is an iconic desk lamp. It’s affordable, has a great industrial design, and looks perfect in any workspace or studio.

However, if you've used it, you probably noticed its one major flaw: the bare bulb is just too bright. Because it lacks a built-in light cover, the direct light causes eye strain and creates harsh shadows on your desk.

We wanted to keep the beautiful design of the TERTIAL while upgrading its lighting quality. That’s why we created a complete, custom-fit add-on.

From Harsh Glare to Soft Glow

The TAKEOUT Light Diffuser catches the blinding direct light and scatters it evenly. It instantly reduces eye fatigue and softens the shadows, making your desk setup perfect for late-night working, reading, or just relaxing.

  • White: Softens the glare while maintaining the original color temperature of your bulb.
  • Yellow: Acts as a built-in color filter, transforming standard light into a cozy, warm, and inviting sunset glow.

Snap It On in Seconds

We designed this to be incredibly user-friendly. There’s no need for screws, glue, or tools.

Just align the diffuser with the inner rim of your TERTIAL lampshade and gently push it in. It securely snaps into place and pops right out whenever you want to remove it. Plus, the minimalist design blends seamlessly with any color of the TERTIAL lamp.
