Description
Calm Green 520nm Light Bulb – Migraine Relief Green Lighting (E27)
If you’re here, chances are you’re not shopping for a “green bulb” for decoration. You’re looking for lighting that feels calmer — because bright household LEDs, office lights, or harsh overhead lighting can trigger or worsen headaches and migraines.
Research into narrow-band green light (around 520–530nm) has reported that this specific colour band can be better tolerated by many migraine sufferers, and in clinical research settings has been associated with reduced headache pain and fewer headache days when used regularly.
How to Use Calm Green Light Bulb
Retreat to a darkened room and allow the gentle green light to fill your space. Spend at least 60 minutes in its soothing illumination (or longer, if preferred).
Additional benefit:
The light output is sufficient for reading, writing, or light tasks, meaning you don’t need to remain completely still during use.
For migraine relief on the go, try our CalmMotion rechargeable handheld migraine device (Green 520nm + 550nm).
Green Light for Headache & Migraine Prevention
Install the Calm Green 520nm E27 Light Bulb in table lamps, floor lamps, pendant fittings, or standard E27 ceiling fixtures to create a calmer indoor environment.
It is commonly used for:
- Migraine relief
- Tension headaches
- Cluster headaches
- Sensory-friendly spaces
Why green lighting can feel different during migraines
Our eyes and brain don’t respond equally to all colours. Many people migraine suffers notice that blue-heavy lighting (common in LEDs and screens) can feel sharper, more stimulating, and more uncomfortable – especially during an attack.
This innovative narrowband 520nm Green LED bulb interacts with ipRGCs, triggering signals that promote a calming sensation for the brain, relaxation & promote better sleep.
Narrow-band 520nm green light bulb is often described as softer and less provoking, which is why some migraine sufferers switch a room or lamp to green during flare-ups or in the evening.
FAQ’s Calm Green Light Bulb 520nm (E27)

Many people with migraine prefer lower-glare, lower-flicker lighting and often avoid blue-heavy LEDs. Research has highlighted narrow-band green light (520–530nm) as a colour migraine sufferers tolerate better.
2) Do LED lights make migraines worse?
They can do, especially bright, blue-heavy LEDs or bulbs with flicker. If you’re sensitive, switching to a calmer green spectrum and flicker-free lighting can help reduce trigger exposure.
3) Is this a “green light therapy” bulb?
It’s a migraine-friendly household bulb for illumination, using a narrow-band green output commonly discussed in migraine research. It’s not a medical device, but it’s designed to create a more tolerable environment.
4) Is green light better than blue light for headaches?
Blue-heavy light is a common complaint for migraine sufferers. Green is often described as gentler, and narrow-band green has been studied in migraine settings.
5) Will any green bulb work the same?
No. The majority of “green” bulbs are coated or colour-mixed and still include more unwanted wavelengths or flicker. Calm Green520nm narrowband light bulb is designed to be flicker-free with ultra-low blue light (1.5%).
6) Can I use calm green light bulb as office lighting for migraines?
Many customers use calm green lightbulbs it in a desk lamp or side lamp to reduce reliance on harsh overhead lighting, especially in the afternoon/evening.
