About RTSUN LED
We are a Shenzhen factory that designs, builds and tests red light therapy devices for professional businesses and growing brands.
Brand story
RTSUN began as an LED lighting manufacturer. When spa owners and wellness founders started asking us to build red light panels, we found that our experience with optics, heat management and constant-current drivers carried over directly.
We rebuilt our lines around phototherapy: spectrometer testing, longer burn-in, medical-grade silicone for masks and modular designs for multi-panel setups. Today we build the full range, from a pocket-size handheld to a 14,400-LED capsule bed.
Founded as an LED lighting manufacturer in Shenzhen, building grow lights and panel lights.
Applied our LED and driver expertise to red and near-infrared therapy devices.
Expanded from panels into masks, belts, mats, stands, pet devices and beds.
Supplying spas, clinics, gyms and DTC brands in 80+ countries, plus factory-direct retail.
Mission
We want a small spa, a new DTC brand and a national gym chain to get the same build quality, test data and support. That means honest specifications, fair factory pricing and MOQs that let new brands start small.
What makes us different
Our team designs optics, drivers and controllers in-house, so problems get solved at the source.
We publish the measurements behind every claim: wavelength, irradiance, flicker and EMF.
We grow when your brand grows, with flexible MOQs and long-term pricing.

Our export team
One person owns your account from first quote to delivery. Message them directly by email or WhatsApp; we reply within 24 hours, usually the same day.
Head of Export Sales
Nalan leads the export desk and is usually the first person new partners speak to. He turns a rough brief (target market, price point, treatment menu) into a clear product recommendation and quotation, then stays on the account through delivery and reorders.
OEM/ODM Project Manager
Ayla runs private-label and custom projects from first sketch to mass production. She translates a brand's requirements into engineering specs, keeps samples, packaging and compliance files on schedule, and sends a written update at every milestone.
Export Sales Manager
Jacken works with DTC founders, Amazon sellers and fitness studios that need fast samples and dependable reorders. He handles quotations, sample orders and freight options, and can tell you which models suit a first launch and which suit a premium line.
