Red Light Therapy Devices, Built to Your Spec

What a Contract Manufacturer Should Prove
Price is the easiest thing to compare and the least useful. These are the six things buyers actually audit before they place a repeat order
Designs stay out of circulation.
Your spec, written once, built by us.
Concept to first shipment.
Reorder to loaded pallet.
Files ready before auditors ask.
We sell under our own labels too, so we know what a launch really costs.
How a Project Actually Runs
Nine stages, one team, one set of drawings that stays with the project from the first call to the last container
Market Analysis
We read demand, competitors and price bands before anyone draws a product.
Product Strategy
Feature set, BOM target and retail price ladder agreed before tooling.
Product Development
Optics, LED layout, thermal path and ergonomics become a design someone can build.
Rapid Prototyping
Working units in your hands, so output, fit and feel can be judged properly.
Compliance & IP
Test files and IP positions prepared alongside the hardware, not after it.
Brand Development
Logo, packaging, manuals and unboxing built around your identity.
Quality Assurance
Burn-in, wavelength checks and safety tests before a single unit ships.
Mass Manufacturing
Repeatable production with batch records and incoming inspection on every run.
After-Sales Service
Spares, export paperwork and technical backup after the pallet lands.
