As a professional medical device manufacturer, DIOSOLE launches 5 models under the YK-6000 phototherapy line for vitiligo, psoriasis, pityriasis rosea and eczema auxiliary treatment. All units target the same skin disorders and follow unified safety standards, yet they split into two core technical lines: 308nm LED portable series and 311nm Philips tube wide-area series. This guide clarifies shared features, key differences and target customer groups to help global distributors match stock to market demands.
Shared Core Advantages Across All YK-6000 Models
Every device in this range serves auxiliary skin phototherapy under physician guidance, forbidden for pregnant and lactating women. All support adjustable treatment timing, automatic power-off protection and digital display for real-time working data. They fit both home self-care and small dermatology clinics, with universal 100–240V wide voltage compatible for global markets. All adopt safe non-invasive UV radiation without oral drug side effects, covering treatment areas including face, neck, limbs, torso, hands and feet.

Line 1: 308nm High-Power LED Series (YK-6000A & YK-6000AT)
This line uses imported 308±3nm LED chips with concentrated high irradiation intensity, designed for small, localized stubborn lesions. LED light sources feature ultra-long service life compared with UV tubes.
YK-6000A
Equipped with 4 LED beads, irradiation area only 2.25 cm² and peak irradiance ≥10 mW/cm². Ultra-light 63g pocket-sized body powered only by USB power banks, ideal for tiny spots on fingertips, lip and eye zones. It suits end users who travel frequently and need pinpoint targeted therapy.
YK-6000AT
Carries 16 LED beads with 9 cm² irradiation zone and ≥7.2 mW/cm² intensity. It is the only model with built-in 2600mAh lithium battery for cordless outdoor use, packed easily into luggage. Perfect for medium local lesions on cheeks, forehead and extremities, a top-selling travel-friendly option for retail channels.
Line 2: 311nm Philips UV Tube Series (YK-6000BT, YK-6000D, YK-6000DT)
All three models adopt original Philips 311±3nm UVB tubes with 1000-hour rated lifespan, delivering mild, uniform radiation for large scattered skin lesions. They require wired power supply and offer broader coverage than 308nm LED units.
YK-6000BT
Single Philips tube with 48 cm² irradiation area, 2.23-inch OLED screen and distance positioning function. Classic comb-shaped handheld design for general full-body scattered plaques, the most cost-effective entry tube model for new distributors.

YK-6000D
Same single tube and 48 cm² coverage as BT, upgraded with flexible bendable handle supporting multi-angle irradiation. Its screen flip function accommodates left and right-handed users, greatly convenient for hard-to-reach back lesions, favored by home users focused on self-operation.
YK-6000DT
Dual Philips tubes creating the largest 63 cm² irradiation area in the whole series. It supports dual usage modes: desktop fixed placement for hands-free back treatment or quick-disassembled handheld mode. Suits clinics and customers with extensive torso and back lesions, a high-margin flagship tube model.
How Distributors Match Models to End-User Demands
For customers with tiny stubborn spots, travel needs or portable retail sales: recommend YK-6000A and YK-6000AT 308nm LED units. For clients with large-area, widespread psoriasis and vitiligo requiring long-term mild home care: stock 311nm Philips tube models. BT fits budget buyers, D targets home self-care users, while DT is ideal for clinic customers and high-spending retail clients.
DIOSOLE provides full OEM & ODM support for all YK-6000 series. Distributors can mix two technical lines to cover all market segments, meeting diverse end-user demands from pocket portable devices to wide-area desktop phototherapy equipment.
