Core advantages

Three reasons buyers switch to RTSUN

Most competitors either sell finished retail products or act as traders. We sit between the two: a real factory that also thinks like a brand.

01
1:1engineer contact

Factory-direct, not a trading company

We design, assemble and test in our own Shenzhen facility, so you deal with the engineers who build your product.

  • No middle-man margin
  • Direct line to engineering
  • Factory audits and video tours on request
02
±5nm tolerance

Measured light, documented specs

Every model is tested with a spectrometer and irradiance meter, and you receive the report to use in sales and compliance.

  • Wavelength accuracy ±5 nm
  • Irradiance mapped at 15, 30, 45 cm
  • Flicker and EMF readings

1–2weeks mass production

Built for your brand

From logo printing to a new mould and app, we take projects from one sample to full container loads.

  • Samples from 1 piece
  • Custom wavelength mixes
  • Packaging, manuals and app UI

Client feedback

What our partners say

We replaced two imported beds with RTSUN capsules. Sessions run 10 hours a day and the sample-to-delivery time was faster than our previous supplier.
Spa group ownerDay spa chain · Germany
Their team sent irradiance data at three distances before we asked. That made our product page and Amazon listing much easier to write.
FounderPrivate-label wellness brand · USA
We put four linked panels on a rolling rack in our recovery room. Members use it after every class and it is now part of our premium tier.
