Revive - 670nm Red Light Bulb by Gamma - Sleep Therapy - Melatonin Promoting Natural Sleep Aid

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.

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!

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.

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.

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.

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

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

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.

Lo volvería a comprar

Item arrived promptly and works great

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