Warm light helps. Red light is the fix.

Cosy is not the same as sleepy. Here is the difference.

Stay in night mode

Why a warm bulb still wakes you up.

Maybe you already made one good move: a warm bedside lamp instead of the bright ceiling bulb. It is a step, not the fix.

It helps. It still feels like normal room light. That is why the same moments stay hard: reading in bed, night feeds, bathroom trips, checking on the baby.

The numbers explain it. Warm white LEDs still put 15 to 21 percent of their light into blue, and cooler LEDs up to 30 to 40 percent.4 The part of your eye that sets your body clock reacts most to blue, and at 670nm it responds at about 1/50,000 of its peak.2

Warm bulb, or red light?

The same bedroom at night. Slide from a warm white bedside lamp to Lampiero.

21% blue

A warm white LED can still send up to 21% blue light into your night.

Blue is the part of white light the body clock reacts to most. The US Department of Energy measured 457 white LED lamps. Even the warm ones carried 15 to 21% blue. Deep red at 670nm carries none.

I carry it from the bedroom to the nursery and back. No cables, no plug. For new parents this is essential. I wish I know about this before.

No screen, no app. Just the right colour.

Lampiero has no screen and no app. It is a red light that feels calm in the exact moments you use it. It lines up with the evening light advice of Dr Andrew Huberman.11

After two hours of evening light, melatonin under red light recovered to 3.5 times the level under blue light.7

Common questions

Red light or warm light at night?

Deep red. Warm white is softer than harsh white, but it still carries 15 to 21 percent blue light.4 Deep red at 670nm is the colour the body clock reacts to least, so the room stays night and you stay sleepy.

Is warm white light bad for sleep?

Warm white is softer than cool white, but it still carries 15 to 21 percent blue light4. Deep red at 670nm is the colour the body clock reacts to least.

Is red light too dim to use properly?

At the lower settings it stays gentle. Slide it up when you need more light, or switch to warm white.

Do I still need this if I use night mode on my phone?

Night mode changes the tint of the screen, not the room, and not the habit of staring at it. Lampiero changes the room.

Can I use it for night feeds and bathroom trips?

Yes. It was made for both. It is portable, rechargeable and easy to carry from room to room, and it dims to a faint glow for a feed.

Should I get one lamp or two?

Almost 1 in 2 customers order two or more lamps. One by the bed and one in the bathroom or the baby's room means you never walk through a dark house or switch on a bright light. Every extra lamp costs less than the one before, and with 3 you get one free.

When will it arrive?

Shipping is free, worldwide. Most orders arrive in 8 to 13 days, tracked. You get the tracking link by email when it ships. See delivery times by country.

What if it does nothing for me?

Use it for 30 nights. If it does nothing for your nights, send it back for a full refund. No hassle.
