Kernal KN-4006BL1D UVB Light Therapy Phototherapy Lamp

Handheld Narrowband UVB Phototherapy Device for Vitiligo and Psoriasis

Available to beauty clinics and dermatology practices for prescribing to patients as a long-term at-home solution.

The KN-4006BL1D is a compact, handheld narrowband UVB phototherapy device built around dual Philips medical-grade 311nm UVB lamps. Designed specifically for home use, it combines portability with precision features — proximity sensing, timer control, and optional smartphone connectivity — to support consistent, physician-guided treatment outside a clinical setting.

Indications

The KN-4006BL1D is positioned for phototherapy workflows involving:

• Vitiligo
• Psoriasis
• Eczema
• Pityriasis rosea

Treatment protocols and suitability should be determined by the treating physician. This device is intended for use as directed by a healthcare provider for at-home phototherapy.

Light Source

Dual Philips Medical 311nm NB-UVB Lamps The light source comprises two Philips medical-grade narrowband UVB lamps, delivering high irradiation intensity and efficiency across the treatment area. PUVA or NB-UVB lamp options are available depending on the treatment need.

Key Features

Compact and Portable Small in size and lightweight, the KN-4006BL1D is built for easy carrying, whether moving between rooms at home or bringing the device along while traveling.

Handheld Operation with Flexible Positioning Handheld use allows the treatment site to be targeted flexibly, rather than being limited to a fixed treatment position.

Acrylic Protective Shield A dust-proof design is paired with an acrylic shield made from special optical materials, providing enhanced protection during treatment.

Timer and Time Working Mode A built-in timer function and time-based working mode improve treatment accuracy and safety by removing the need for manual time calculation, with a countdown display to help patients track session progress in real time.

Internal Lithium-Ion Battery Powered by a replaceable lithium-ion battery, the device can be operated cord-free, adding convenience for home use without being tied to a power outlet during treatment.

Proximity Sensor with Positioning Bracket A proximity sensor paired with a positioning bracket helps users quickly and accurately locate the correct working distance, supporting more precise, consistent treatment sessions.

Smart Treatment via Bluetooth (Optional) An optional Bluetooth function allows the device to connect with a companion smartphone app, offering complimentary treatment consultation support alongside home use.

Case Management Built-in case management functionality supports efficient medical record keeping, allowing for swift retrieval of patient treatment information — useful for both patient self-tracking and physician review.

The manufacturer warrants to the original purchasing entity ("Buyer") — including hospitals, clinics, and other licensed medical institutions within the United States — that the hardware product sold shall be free from defects in materials and workmanship under normal clinical use for a period of one (1) year from the date of shipment. This warranty is provided in addition to, and does not affect, any rights the Buyer may hold under applicable state or federal law.

2. Depot-Only Return Procedure

Warranty service is strictly a depot-return process conducted directly by the manufacturer of this particular product.

• First Step (Intake): To initiate a warranty claim, the Buyer must not contact the manufacturer directly. The Buyer must first contact Medaza, Inc. by email at contactusa@medaza-platform.com.
• Delegation: Upon receipt of the email, Medaza, Inc. — acting in its capacity as distributor — will delegate and coordinate the direct connection between the manufacturer (or the manufacturer's designated U.S. Initial Importer, where applicable) and the Buyer, facilitating return logistics and securing the required Return Merchandise Authorization (RMA) number.
• Shipment: No shipments will be accepted by the manufacturer's facility without an active, authorized RMA number. The product must be securely packaged in its original packaging (or equivalent protective packaging), with all patient-identifying information removed or de-identified in accordance with the Health Insurance Portability and Accountability Act (HIPAA) and other applicable privacy laws prior to shipment, and shipped directly to the designated service facility of the manufacturer.

3. Allocation of Shipping Costs (Two-Way Shipping)

The Buyer assumes full financial responsibility for all shipping logistics, packaging, handling fees, customs/tariffs, and insurance transit costs associated with the warranty claim. This includes:

• Inbound Shipping: The cost to safely transport the product from the Buyer's facility to the designated service location of the manufacturer.
• Outbound Shipping: The cost to return the repaired or replaced product from the manufacturer's facility back to the Buyer's designated location within the United States.

4. Recall & Systemic Defect Exception

The shipping cost allocation in Section 3 shall be waived solely in the event that the returned product is officially determined by the manufacturer, its designated U.S. Initial Importer, Medaza, Inc., or the FDA to be subject to a Recall, Safety Alert, or a verified batch-wide Systemic Manufacturing Defect, in accordance with 21 CFR Part 806 (Medical Device Reporting: Corrections and Removals) and related FDA recall procedures. In such extraordinary circumstances, the manufacturer will cover standard two-way ground shipping costs.

5. Warranty Exclusions

This warranty does not cover:

• Disposable clinical consumables (including but not limited to needles, sutures, applicators, and single-use accessories) once packaging is opened.
• Damage caused by accident, abuse, liquid spills, improper sterilization or disinfection, neglect, patient misuse, or unauthorized modifications or repairs.
• Damage resulting from use outside the manufacturer's labeled indications, intended use, or instructions for use (IFU).
• Normal wear and tear, consumable component degradation (e.g., lamps, filters, probes), or cosmetic degradation that does not affect device function or safety.
• Any device on which the serial number, UDI (Unique Device Identifier), or product identification label has been removed, altered, or defaced.

6. Adverse Event Reporting

Nothing in this warranty limits or replaces the Buyer's independent obligation, as a healthcare institution or professional user, to report device malfunctions, serious injuries, or adverse events involving this product to the manufacturer, to the manufacturer's designated U.S. Initial Importer (where applicable), to Medaza, Inc. as distributor, and, where required under 21 CFR Part 803 (Medical Device Reporting), to the FDA (e.g., via MedWatch). Medaza, Inc. will cooperate with the manufacturer, the Initial Importer, and the FDA on any resulting investigation, corrective action, or reporting obligation.

7. Distributor Obligations Notice

For this product, Medaza, Inc. acts solely as a distributor; a separate entity — not Medaza, Inc. — handles importation and fulfills any applicable U.S. Initial Importer obligations under FDA regulations for this manufacturer's products. As distributor, Medaza, Inc. confirms it verifies that the device bears the required labeling and UDI, that it is accompanied by the manufacturer's required documentation, and that appropriate storage and transport conditions are maintained while the product is under its responsibility. This warranty does not alter or diminish those regulatory obligations, nor does it impose importer obligations on Medaza, Inc.
