The Right Light, Morning to Midnight

Most bulbs give you the same hard light at 11pm as they do at 8am. This one changes with the day — flick the switch to move between three modes.
Full-spectrum white for mornings — bright and clear as daylight
Warm amber for evenings — zero blue light, like candlelight
Deep red for the last hour — enough to see by, soft enough to leave on

Gemma C
This is the only light we use and has been Great to not have bright lights in the lounge in the afternoon. Especially good for our nearly 1yr old to have calm lighting before bed. Highly recommend.
Sacha S
These lights are the perfect addition to our home. Soft lighting for when you are winding down or waking up slowly and bright light when you need it.
Melanie P
We are loving our evenings with this light bulb. It sets the mood for sleep time. I never knew how much impact our lighting has on our circadian rhythm.
Yvonne B
I absolutely LOVE this product. It is so beautifully calming. I use it at night before I go to bed, I use it when I shower, and the white noise to put me to sleep. I’m obsessed
Maggie S
This light has been an absolute game changer for me. I love that I can change the spectrum of light with just the flip of the light switch. It’s improved my sleep too!

Light is how your body tells the time

For most of human history, the only clock anyone had was the sky.

Bright and blue overhead at midday, low and orange at sunset, black after that. Modern lighting flattened all of it into one setting and left it there.

01

Full-spectrum white in the morning, the way daylight is

02

No blue wavelengths in the evening, the way firelight never had any

03

Deep red at night — the faintest signal there is

One Bulb. Every Room, Every Hour.

Common Questions

Everything worth knowing before you screw it in.
  • It's 7W. A traditional bulb giving similar warm light burns around 60W and lasts a fraction as long. If you've been buying old-style bulbs to get warmer evening light, this replaces them and costs less to run.

  • No. Most cheap LEDs flicker hundreds of times a second — you don't see it, but it's part of why some rooms feel tiring to sit in. This one is flicker-free, so it stays steady whether it's on for ten minutes or all evening.

  • It fits any standard E26 socket — the regular medium screw base used in most US table lamps, floor lamps and ceiling fittings. If your lamp takes a smaller candelabra bulb (E12), this one won't fit. Check the base of the bulb you're replacing.

  • Flick the wall switch or lamp switch off and back on. Each flick moves it to the next mode. No app, no wifi, no hub, no remote to lose.

  • 400–600 lumens depending on the mode — roughly the same as a 40–50W old-style bulb. Right for a bedside lamp, a floor lamp or a small ceiling fitting. It isn't a floodlight, and it isn't meant to be.

  • No. It isn't dimmable and shouldn't be used in a fixture with a dimmer. It's built to change modes with a standard on/off switch instead, so it works in any normal lamp.

  • Rated for 50,000 hours. Used every evening, that's roughly ten years.

To address a sleep challenge that intensifies with age, I have implemented a strategy to minimize melatonin disruption by avoiding bright lights before bedtime. Through research, I discovered that red light is the most effective option to preserve circadian rhythms. Consequently, I have installed red light bulbs in my shower and bedroom, particularly during nighttime sleep when bright lights are not conducive to rest. In summary, I recommend the red light bulb. The bulb appears solid and constructed with quality in mind. Additionally, its smaller size compared to a traditional bulb makes it more versatile in terms of its placement. It is too early to attest to the bulb’s lifespan, but I am happy to provide an update should there be a quality concern.

Great light bulbs. (4pack) The orange color is right on point. I’m going to use these bulbs in the fall for Halloween in my outdoor garage lights.

Jessica

Worked perfectly for our Halloween party!!

K

I really like these for my redrum/the shining themed bathroom I did for Halloween. It made the entire room look more realistic and gave that movie effect I was looking for. For some reason I did not expect them to be as bright as they are, like squint your eyes bright, but that’s fine.

Light bulbs so far work great. I purchased them because I read that nocturnal animals like bags are not affected by these red led lights bulbs. I was worried it would look too Christmasy but I actually like the color. Works for our needs

B
Bobby

When I first opened the box, I was surprised to see that these bulbs are white, and they are small. However, the base of these bulbs is a standard E26 size, so they fit into the standard socket. I needed some red sleep bulbs for my newborn granddaughter. These will work perfectly.

A

These bulbs give off a pleasant red/orange glow that offers effective illumination without being harsh on your eyes. They're nice for a living room, bedroom, or nursery where you appreciate the illumination, but want something suttle in place of an overly bright white or yellow light. They're soft enough that honestly you could use them as a night light or keep them on while you sleep.

Red light bulbs like this one are gaining attention for their potential to create a sleep-friendly environment. While I’ve long known — thanks to my military experience — that red filters help preserve night vision, I wasn’t aware of their possible benefits for sleep until recently. There’s a growing body of both anecdotal and clinical evidence suggesting that blue light from screens (TVs, phones, computers) can disrupt natural sleep cycles. As a pragmatist, I prefer to test things for myself — so it's too early to confirm any long-term sleep improvement. But I’m giving it a shot. The bulb itself is well made, and being LED, it's also energy efficient. It casts a noticeable red glow, which definitely changes the mood of the room. If you live in a neighborhood where homes are close together, don’t be surprised if the glow sparks some curiosity from your neighbors! Overall, this is an affordable product worth trying. If it helps improve your sleep, great — and if not, you're only out a few bucks.

So bright for my dark bathroom.

C
Curtis

These light bulbs are excellent. They are extremely easy to set up, the installation is a simple as inserting the base into a socket and turning it, righty-tighty to plug in and left-loosey to remove.

A

The bulb’s light very bright love them

B
Brooke

These light bulbs are great. I struggled at all of the local stores to find something like this. I love them. And for the price. Well deserved 5 star.

T
Taylor

Amber/ orange prefect color for night light or nightstand. 100% as described.

E
Elliot

Gorgeous color, relaxing vibes

E
Ericka

The bulb is small but it is E26 which will fit most lamps. It gives a great cozy vibe to the room.

J
Jocelyn

These light bulbs definitely create a cozy, warm atmosphere that’s great for relaxing before bed. I appreciate the blue light blocking feature, which feels helpful for promoting healthier sleep. However, the color temperature is a bit too warm for my taste, I prefer something warm but not quite this deep amber. The light they emit is soft and gentle, making them perfect for bedrooms or night lights, but probably not the best choice if you need brighter light for reading. They do their job well as dim lamps, and the 2-pack offers good value.

Great color and bright enough for darkness

Exactly what I was looking for to bring warmth to my home!

E

Just the lighting I was looking for and the price can't be beat!

T
Tak

These bulbs offer enough light to keep our entrances well lit, but at the same time, the reduction in the number of insects hanging around the doorways is fantastic. I am sure no bulb can completely eliminate bug activity, but these greatly reduced the number and no more moths getting in the house when I come home from work.

P
Pily

Soft ambient light, gentle on eyes for the morning and ease into bed at night.

R
Rayn

Remodeling my hallway to match the rest of my house, I HATE white lights they aren’t calming or relaxing, found these and everyone has made comments so far that my hallway gives warm homey vibes- they were too bright for all four so in this picture is only two (one in each fixture). Worth the money!

N
Noah

The night setting is dim enough to feel calm but still useful. No extra controls to lose, just the wall switch. Mine is in a lamp beside the sofa.
