• KN-4004B — Dedicated NB-UVB System

Equipped with 8 × 100W NB-UVB lamps, the KN-4004B is designed for facilities primarily providing full-body narrowband UVB phototherapy.

• KN-4004AB — UVA + NB-UVB System

Equipped with 4 × 100W UVA and 4 × 100W NB-UVB lamps, the KN-4004AB offers greater treatment flexibility. UVA and NB-UVB can be operated independently or simultaneously according to the selected phototherapy protocol.

For safety, when accepting the irradiation, the patient should stay 7.9 inches | 20cm away from the lamp.

14,771 cm² Large-Area Irradiation

Cover more skin in one treatment setup. The 14,771 cm² effective irradiation area is designed for widespread or multi-area skin conditions, reducing the need to repeatedly reposition a small handheld phototherapy device.

Adjustable Dual-Wing Design for Flexible Body Coverage

The double-opening cabinet design allows both side panels to be adjusted to different angles according to treatment needs. This flexible configuration helps optimize light coverage across different body areas and makes it easier to adapt the system for large-area or targeted phototherapy.

8 × 100W Philips Lamps for Broad, Consistent Coverage

KN-4004B is equipped with 8 × Philips TL 100W/01 NB-UVB lamps, providing 311nm ± 3nm output across the large treatment area. The KN-4004AB configuration combines 4 UVA and 4 NB-UVB lamps for facilities requiring both modalities.
