The Yonker YK-6000 is a portable Class II medical UVB phototherapy lamp designed for home use. It emits narrowband ultraviolet light (listed at 311 nm) and is intended to assist in managing skin conditions such as psoriasis and vitiligo.
The device is intended for use as phototherapy support for conditions including psoriasis and vitiligo. It is also sometimes used adjunctively for certain eczema or herpes-related skin issues. Always consult a dermatologist to confirm whether phototherapy is appropriate for your condition.
The specification for this model lists a 311 nm wavelength (narrowband UVB), which is commonly used in phototherapy. The product name also references 308 nm; if a specific 308 nm output is required for your treatment, verify the exact model/wavelength with the seller before purchase.
Follow the user manual and your clinician's instructions. The specified working distance for this unit is approximately 3 ± 0.5 cm from the skin. Treat clean, dry skin, protect eyes with approved goggles, and avoid directing the lamp at non-target areas. Begin with short exposure times as directed by a healthcare professional.
Treatment frequency and duration depend on your skin type and condition. Do not self-prescribe doses; start under medical guidance. Your dermatologist will recommend a safe starting exposure and a schedule based on response and tolerance.
Regulations vary by region. Many dermatologists recommend or require medical assessment before home phototherapy. Consult your healthcare provider and check local regulations; use only under clinician supervision if recommended.
Short-term side effects may include redness, itching, dryness, or mild burns if overexposed. Long-term UV exposure can increase risks of photoaging and skin cancer. Use protective eyewear, follow dosing guidance, and have regular medical follow-up.
People with a history of photosensitivity disorders, certain skin cancers, or those taking photosensitizing medications should avoid or use it only under strict medical supervision. Pregnant or breastfeeding individuals should consult their healthcare provider first.
Some topical agents increase photosensitivity (for example, certain psoralens or other sensitizing medications). Only use topical treatments in combination with phototherapy when advised by your dermatologist and follow their instructions.
Always wear protective UV goggles to shield the eyes, cover unaffected skin and mucous membranes, and avoid exposure to tattoos or areas with skin cancer or suspicious lesions. Follow clinician and manufacturer safety instructions.
The single package size is approximately 40 x 25 x 10 cm and the gross weight is about 2.0 kg, making the unit lightweight and portable for travel. Confirm power requirements and accessories with the seller before travel.
Turn the device off and unplug it before cleaning. Wipe the exterior and lamp window gently with a soft, dry or slightly damp cloth. Do not immerse the unit in water or allow liquids into ventilation openings. Follow maintenance instructions in the user manual.
The device is listed as a Class II medical instrument. Warranty length and additional certifications can vary by seller/region—verify CE/other regulatory markings and warranty terms with your supplier before purchase.
The product listing specifies a single selling unit but does not list included accessories. Check the seller’s product page or contact the vendor to confirm whether protective goggles, power adapters, or carrying cases are included.
Stop using the device immediately and contact your healthcare provider if you experience severe redness, blistering, severe pain, or any signs of an unexpected reaction. For eye discomfort after exposure, seek medical attention promptly.
