Why shoppers choose NorbRELIEF
A dedicated green bulb—not a decorative bulb set to green
NorbRELIEF is designed around a measured narrow-green spectrum, flicker-free operation, and ordinary home use. It provides an inexpensive way to explore a different lighting environment without purchasing a specialized lamp or medical device.
Measured near 520 nm Product output is documented through spectral measurement.
Flicker-free design Made to avoid the visible or imperceptible flicker associated with some LEDs.
Standard lamp compatibility The common A19 shape and E26 base fit many household lamps.
Low-commitment purchase Start with one bulb for $21.95 rather than buying a dedicated fixture.
Use it in an ordinary lamp
Keep green light ready where sensitive periods happen.
Place NorbRELIEF in a bedside lamp, home-office lamp, reading light, living-room fixture, or dedicated recovery space.
The bulb produces visibly green illumination. It is intended for purposeful use when ordinary white lighting feels too harsh—not as a whole-home replacement for normal lighting.
The dimmable design allows use at a lower intensity when paired with a compatible fixture.
Why not buy a normal green bulb?
Green appearance does not guarantee narrow-green output.
Ordinary green-coated bulbs and color-changing LEDs can make a room appear green, but their actual spectral output depends on how they are constructed.
NorbRELIEF’s measured output is concentrated near 520 nm rather than relying solely on a green coating or a general-purpose RGB setting.
That distinction does not guarantee a medical result. It does help shoppers choose a product designed specifically for narrow-green use rather than decoration.
Product measurement
See the measured 520 nm output.
A spectral meter records the wavelengths actually produced by a light source. NorbRELIEF’s output peaks near 520 nm, within the green portion of the visible spectrum examined in migraine-light research.
The graph documents the bulb’s output. It should not be interpreted as proof that every user will experience symptom relief.

Designed for more than sitting in complete darkness
Participants in Norb’s four-week user-experience study placed NorbRELIEF in bedrooms, offices, kitchens, and living spaces.
They described using it while working on computers, preparing for the day, watching television, creating art, resting, and winding down at night.
The study included four participants and was not a randomized clinical trial. Individual experiences do not guarantee results.

Purchase questions
What to know before ordering
Is NorbRELIEF intended to cure migraines?
No. NorbRELIEF is not a cure or medical treatment. It is a household lighting product designed to create a narrow-green environment that some people may find more comfortable during light-sensitive periods.
Should I order one bulb or the four-pack?
One bulb is best for trying NorbRELIEF in a single room. The four-pack costs approximately $17.49 per bulb, saves $17.85 compared with four single bulbs, and receives free shipping.
What kind of lamp does it fit?
NorbRELIEF is an A19 bulb with a standard E26 medium screw base. It fits many ordinary table lamps, floor lamps, and compatible fixtures.
Can I dim the bulb?
Yes, when used with a compatible dimmer or dimming fixture. Beginning at a lower intensity may be preferable for people who are sensitive to light.
Is it the same as a green smart bulb?
No. A smart bulb uses its available LED channels to produce multiple selectable colors. NorbRELIEF is a dedicated narrow-green bulb with measured output concentrated near 520 nm.
Why can colors look purple after the light is turned off?
After spending time under green illumination, some people temporarily notice a purple or magenta tint when the bulb is turned off or when looking at a white surface. This is a complementary-color afterimage caused by temporary adaptation of the eye’s color-sensitive photoreceptors. It typically fades as normal color vision readjusts. Stop using the bulb and seek guidance from an eye-care professional if a visual change persists, occurs without recent green-light exposure, or is accompanied by other unusual symptoms.
How much is shipping?
Shipping is a flat $5 for orders below $55. The $69.95 four-pack qualifies for free shipping.
Can I return the bulb?
Eligible purchases may be returned within 30 days under Norb’s current return policy. Qualifying defective bulbs are covered by a two-year warranty from the purchase date.
