Benefits of 670nm Red Light Therapy
Red light is unique in its ability to preserve the body’s natural circadian rhythm, unlike other light wavelengths that can interfere with your sleep. Most common light sources, such as those from screens or overhead lighting, emit blue wavelengths. These blue wavelengths are particularly disruptive because they suppress melatonin production—the hormone that tells your body it’s time to rest. When melatonin levels are reduced, it can be harder to fall asleep and maintain a healthy sleep pattern.
In contrast, red light is free from these harmful blue wavelengths, making it a better choice for evening or nighttime use. It allows the body to continue its natural production of melatonin, helping you fall asleep more easily and maintain a regular sleep cycle.

The Science Behind Red Light Therapy
The 670nm wavelength stimulates the production of melatonin, the hormone that plays a crucial role in regulating your body’s sleep-wake cycles. By promoting the natural alignment of your circadian rhythm, this specific wavelength helps signal to your body that it’s time to relax, making it easier to fall asleep quickly and experience deeper, more restorative rest. Safe, non-invasive, and easy to use, our lamp provides a natural and effective solution to improve your sleep quality and boost relaxation.
Recent human studies have demonstrated the positive effects of red light therapy on sleep. Participants exposed to 670nm red light saw significant improvements in both sleep quality and duration when compared to those in the control group. The results show that regular exposure to red light before bed can help foster better sleep habits, making it an ideal option for those seeking a natural way to address sleep disturbances.

Frequently Asked Questions
How do I use the Revive Bulb? We recommend using the Revive Light Bulb for around one hour before bedtime. Other lights should not be used as blue and white light will interfere with sleep. The light can be left on overnight so that when you wake, it can help you safely navigate your space or you can use the light with a timer to shut off after you are asleep. Can I change brightness? No, this bulb cannot be dimmed. It is designed to operate at a fixed brightness and is not compatible with dimmer switches. Using it with a dimmer switch may cause flickering or reduce the lifespan of the bulb. If you need dimmable lighting, please choose a bulb specifically labeled as dimmable. Do my eyes need to be open? When using the Revive Light Bulb, your eyes do not need to be open for it to be effective. The 670nm red light works by creating a calming environment that helps prepare your body for sleep. You can use the lamp with your eyes open or closed, as the red light helps signal to your brain that it’s time to wind down for the night. Why is 670nm light different? Studies have shown that pure red light at a wavelength of 670nm is best for sleep. Red light can be found in a spectrum of 620-750nm. Our Revive Light Bulb is specifically and precisely designed at 670nm.

Very bright bulb. Doesn’t interfere with sleep
This bulb is very bright! It keeps the bathroom brightly lit without interfering with sleep even though some of the light comes through to the bedroom. Makes using the bathroom at night safer for elderly people.

It’s actually 670nm
Supposedly 670nm is the magic number where the red light will penetrate into your cells and stimulate your mitochondria to improve energy and cell function, as well as things like eyesight. I mostly wanted a red light to reduce melatonin suppression, but figured if I could also give my mitochondria a boost, I might as well.I bought a different brand, and using a cheap spectroscope I discovered that it wasn’t 670nm as claimed, so I bought this one. It is spot on at 670nm. It’s probably not enough light output for any meaningful boost to the mitochondria, but hey, they didn’t lie about the light spectrum, which is refreshing!

Helps with poor sleep
Ngl it’s expensive and seems like a scam but it works. Normally wake up frequently at night but slept more soundly from day one using this 670nm bulb. Theorize all the bright LED (source of HEV blue light from TVs, monitors, light bulbs, etc.) and little real sunlight exposure is the cause behind the sleep disruption. Currently in an old lamp post, no shade, placed near the bed, and plugged into a cheap automatic timer. The light is strong and will illumimate the entire room in red, contrary to the small localized light portrayed in the product description photo. Color is a deep, soft red compared to red party lights. The blood red color is macabre to be frank but thinking it’s light therapy helps to get over the aversion. Bulb lifespan is listed as 50k here (about 17 years if used for 8 hours every night) but the product website states it’s 20k (about 7 years if used 8 hrs a night) with 1 year warranty. It’s wait and see how long the bulb will really last.WIP: Experimenting with exposure duration efficiency. Currently set to 3hrs.

If you have trouble falling asleep at night, this is for you.
These are great bulbs. I know you can find them cheaper, and I’m not a light wavelength expert, but I feel like a little extra money is probably worth it in this case because I’m looking for genuine near infrared. I have lights that come on automatically an hour before bed, and then I turn off the white lights. They’re bright enough that I can see in my apartment, using red lights before bed has changed my life, no joke. I’ve suggested this to friends and actually had someone call me last night and tell me that it did the same for them. If you have trouble sleeping, cut out all the regular light and all the gadgets and run these for an hour before bed. It works.

Great quality! But high price
Perfect brightness, deep red color, good quality. Using in a lamp in our bedroom to turn on during diaper changes, bright enough for us to see clearly throughout the room and see what we are doing, but color prevents the light from waking our baby up or messing with our own sleep quality during those night duties. Hoping this lasts a long time, my only complaint is the price… so expensive for one bulb!! But, we wanted to be sure we had a true red light with no color light dilution, and we didn’t want an off-brand Chinese unregulated/tested bulb to thread into our lamp due to fire safety concerns.

The perfect light for a bedroom at night
I’ve been using this light for months now, and I’ve really noticed an improvement in my sleep and how soothing it is for my eyes

Didnt last longer than a night
Absolute junk. Worked for one night in my lamp. Worked great for that night too. I did seem to sleep better. But after I turned it off in the morning, it never turned back on. I even tried it in different bulb sockets with light bulbs that are working. Nothing. Make it last longer than a night and ill buy one

Helps Me Relax and Fall Asleep
I like this lightbulb. It helps me relax and get ready to sleep at night, which has always been a challenge. When it gets dark outside, I turn off all the lights in the living room and then turn this red light on. Then I put on my nighttime blue blockers while I am on the computer or when I watch TV. It has been a game changer. I never even make it through a single show with this routine. I helps me zonk out. It was totally worth the price I paid for this bulb. My plants hate it though. Some of them are on the same end table as the lamp with this red light. If fall asleep and fail to turn it off, they are exposed to the light all night to the light. I can see them literally leaning the opposite direction, trying to get away from it.

Sehr hell und wahrscheinlich gute Qualität.

I tried buying the knock off version of this bulb for half the price, but they’re yellow compared to these bulbs. The knock offs also weigh less and power consumption in watts is also less. This bulb feels heavy duty and puts out very nice red colour.

Very bright. Testing it out for the supposed melatonin effects. Works great as a red light though. Nice to read by before sleep.
