Lumerin started because I couldn't find what I was looking for.
I was 22, had just finished an engineering degree, and was looking for a lamp for my bedroom. Not a complicated ask. I wanted something with a warm, amber glow — the kind of light that makes a room feel like it's winding down rather than switching on. Something that looked considered, not just functional. And something that didn't cost the same as a month's rent.
It doesn't exist. Or at least, not in the way I wanted. The cheap options were dull. The good-looking ones were expensive and still didn't get the light quality right. Most lamps are designed for how they look in a brightly lit showroom, not for how they make a dark bedroom feel at 10 at night.
So I made one instead.
Starting with a printer and no real plan
I already had access to a 3D printer through my engineering course. I understood the materials. I knew that PETG — a transparent, recyclable plastic — diffused light beautifully when printed at the right thickness. I started designing shades, printing them, holding them up to a bulb in a dark room, and seeing what happened.
Most of them weren't right. The proportions were off, or the print lines were too visible, or the light distribution was uneven. I'd iterate. Print again. Hold it up to the bulb again. The first design I was actually happy with took somewhere around ten attempts to get right — and that's still roughly how the process works now.
The engineering background turned out to matter more than I expected. Not because lamp design is technically complex, but because it taught me to treat every version as a test rather than a failure. You don't stop when something doesn't work. You change one variable and try again.
Why the materials matter
Every Lumerin lamp is made from two materials. The bases are printed in PLA — a bioplastic derived from corn starch that biodegrades slowly over time. The shades are printed in transparent PETG, which can be recycled at suitable recycling centres.
I didn't choose these materials just for environmental reasons — though that matters. I chose them because they're the right materials for the job. PLA gives a clean, matte finish for the base. PETG transmits light in a way that feels warm and organic rather than plastic and harsh. The materials and the aesthetics happen to align.
Made in the UK, printed to order
Every lamp is designed, printed, and assembled by me in the UK. I don't hold large amounts of stock — most lamps are printed when an order comes in, which means less waste and more consistency. Each one is checked before it's packed.
That's not a scalability story, it's just how I want to make things. A lamp that takes ten prototypes to get right deserves to be made properly.
What Lumerin is for
The lamps aren't trying to be the loudest thing in a room. They're designed to make a room feel better — warmer, softer, more settled. The 2700K warm white light is a deliberate choice. The shade geometry is a deliberate choice. Even the scale of each lamp is chosen so it works on a real bedside table or shelf, not just in a styled photoshoot.
If you've ever walked into a room and immediately felt more relaxed without knowing why, the lighting did most of that work. That's what I'm trying to put in a box and send you.
