Beta · Holiday 2026 batch

Light up someone's room from anywhere.

Lumen is a smart LED strip your friends can glow. Tap a coin on your desk and their wall lights up in your color, whether they're down the hall or across the country.

Try it. That's the whole product.

Why Lumen

A text says "thinking of you." A wall that turns your color says it without words.

Other smart strips are remote controls for your own room. Lumen connects rooms. Every kit ships with the same great light, plus the part nobody else has: your people.

Friend-connected strips

Add a friend in the app. From then on, either of you can light the other's strip with a glow: a color, a pattern, a mood. It fades on its own, or they tap to clear it.

Coins you can hold

Each NFC coin is tied to one action. Set one on your nightstand for "goodnight." Tap it. Their room glows. No phone, no app open.

Live context

Pick a team and your strip pulses on every score. Set a reminder and it fades in as blue light instead of another notification.

Great light on its own

A 5 m seamless COB strip, no visible dots, driven by an open WLED core with 100+ effects. Music mode, scenes, schedules, and the whole thing keeps working with no subscription.

How it works

Three steps. About four minutes.

STEP 1

Plug in one cable

Stick the strip, plug in the controller, open the Lumen app. It finds the strip and joins your Wi-Fi from inside the app. You never leave it.

STEP 2

Add your people

Send a friend request by username. Once they accept, you can glow each other, and you'll see when their strip is on.

STEP 3

Tap a coin

Hold a coin to your phone once to set what it does. After that, tap it on any phone, or just leave it on the desk and tap when you think of them.

Coins

Small, brass-colored, and each one means something.

Every kit includes NFC coins. Assign each one in the app, then keep it where the moment happens.

Presence

Goodnight

On the nightstand. One tap, their room goes warm amber and fades out over ten minutes.

Presence

Home safe

By the door. Tap when you're in. Mom's strip blinks green twice and settles.

LUMEN
Reminder

Take your meds

Schedule it. The strip fades in blue at 9 pm and stays until the coin is tapped.

LUMEN
Scene

Movie night

Tap to dim your own strip to a low ember. Tap again to bring the room back.

Anything

Any glow, any friend, any strip. Re-assign a coin whenever you want.

Thirty days from the day it arrives. Full refund, no form, no questions. We'd rather have the kit back than have it sit in a drawer.

From the founders

"We're a brother and sister who moved from San Diego to Tempe. We built this so a lamp turning on could mean 'I'm thinking about you' without anyone picking up a phone. The first batch is small on purpose. You'll be talking to us."

Questions

Things people ask before they reserve.

Does my friend need a Lumen too?

To glow each other, yes. That's why the Duo exists. A Single is for joining someone who already has one, or for coins and scores in your own room.

Is there a subscription?

No. The app, friends, glows, coins, and updates are included. We may add optional extras later, but nothing you buy today gets taken away.

How hard is setup, really?

Peel, stick, plug in one cable, open the app. The app joins the strip to your Wi-Fi from inside the app. Most people are done in about four minutes. If you get stuck, you text us.

What do I need on my phone?

An iPhone running iOS 17 or later, with Wi-Fi. Coins work with any NFC-capable phone. Android app is planned for 2027.

Can I use it as a normal light strip?

Yes. Colors, effects, music mode, schedules, brightness. It's a great strip even if you never add a friend.

What if it doesn't work for me?

Send it back within 30 days of delivery for a full refund. No questions.

When does it ship?

The first batch ships in December 2026. Reserve now and we'll email you the exact date and a checkout link before anything is charged.
