Philips TL 20W/01 RS UVB Narrowband Replacement Bulb

UV-B Narrowband TL Replacement Bulb - TL 20W/01 RS SLV/25 - For Phototherapy Systems

The Philips TL 20W/01 RS UVB Narrowband Replacement Bulb is a professional-grade ultraviolet lamp designed for applications requiring precise UVB narrowband radiation centered at 311 nm. With a controlled emission range between 305–315 nm, this lamp delivers highly targeted UV output commonly used in phototherapy systems, agricultural applications, and specialized curing processes. Its reliable output and consistent spectral performance make it a trusted replacement lamp for professional UVB equipment.

Engineered in a T12 fluorescent format with a G13 bi-pin base, this 20-watt lamp fits standard 2-foot UVB narrowband devices, including many medical hand and foot phototherapy units. The lamp offers stable UV performance with predictable depreciation characteristics, making it suitable for facilities requiring consistent treatment intensity or repeatable UV exposure conditions.
