Product Focus

Build Around a Defined Green-Light Output

For a special-wavelength bulb, the complete spectrum and operating conditions matter more than a catalog color name. Confirm the wavelength, electrical configuration, optical output and packaging before approving production.

λ

Narrow-Band Target

Define the peak wavelength, spectral width and tolerance. “Pure green” or “no blue light” requires model-specific spectrum evidence.

A19

A19 & E26 Platform

A familiar bulb shape and screw base support evaluation in compatible indoor fixtures. Other configurations require review.

OEM

Private-Label Ready

Discuss lamp markings, model codes, instructions, boxes, barcodes and master cartons for your sales channel.

Specifications

Confirm the Exact Model Before Ordering

The shown product is marked as an A19 E26 520nm bulb with AC 85–265V input. Other performance values require confirmation against the selected driver and approved sample.

Buyer note: Define the required wavelength tolerance, spectral width, blue-spectrum leakage, optical output, flicker metrics, dimming range and test distance where relevant.

Application Development

A Platform for Specialty-Lighting Evaluation

Lighting brands, importers and product developers can evaluate this platform for controlled-spectrum, specialty ambient-lighting or wellness-oriented product concepts.

  • Controlled-spectrum lighting evaluation
  • Wellness-lighting product development
  • Specialty ambient-lighting ranges
  • Prototype and research-oriented projects
  • Private-label programs for defined markets
Responsible Positioning

What Research Does—and Does Not—Establish

Light can affect alertness, melatonin and circadian timing, but response depends on wavelength, intensity, timing, duration and individual conditions. A wavelength label alone does not prove a sleep benefit.

Research context

Human studies involving green wavelengths around 520–525nm have reported circadian or melatonin effects under specific experimental conditions.

Product claim boundary

MoreBulb does not currently claim that this bulb improves sleep, treats migraines, increases melatonin, treats insomnia or manages a sleep disorder.

Customers developing wellness or clinical applications should complete application-specific testing and obtain appropriate regulatory advice.

OEM & Private Label

Configure the Product for Your Market

Feasibility, testing, tooling, MOQ and schedule are confirmed before quotation.

01

Optical Requirement

Define wavelength, tolerance, output, operating distance and flicker requirements.

02

Electrical Configuration

Confirm voltage, frequency, wattage, base and compatible fixture conditions.

03

Brand & Packaging

Review bulb printing, labels, instructions, boxes, barcodes and cartons.

Quality Workflow

From Requirement to Approved Production

Manufacture against a controlled specification and approved sample—not only a reference image or color description.

Illuminated-batch reference. Final inspection criteria should define wavelength, output and appearance tolerances.

Requirements

Share the target, rating, quantity, packaging and destination market.

Sample & Data

Review the physical sample and agreed model-specific measurements.

Production

Follow the approved specification, components, markings and packaging.

Verification

Check electrical performance, appearance, labeling and packing before release.

FAQ

520nm Green LED Bulb Questions

What does 520nm mean?
It refers to the nominal peak wavelength. The actual peak, tolerance and spectral width should be confirmed using model-specific test data.
Is this bulb proven to improve sleep or relieve migraines?
No product-specific clinical claim is currently made. Published research does not establish that this bulb improves sleep, relieves migraines or treats a medical condition.
Is it narrow-band with no blue light?
Claims such as “narrow-band,” “pure green” or “no blue light” must be confirmed against the complete spectral power distribution and agreed limits.
Is it dimmable and flicker-free?
These depend on the selected driver and dimmer. Define the dimming range and measurable flicker criteria before sample approval.
Can you provide a spectrum report?
Ask for available model-specific data when requesting a sample. Test conditions and acceptance criteria should be agreed before production.
What are the MOQ and lead time?
Standard MOQ is 5,000 pieces. Standard lead time is 30 days after the order, specification and packaging are confirmed.
Which compliance documents are available?
CE, RoHS and SAA documentation is available for applicable products. Coverage must be checked against the exact model and target market.
