QTX 18W 2ft T8 Fluorescent UV Tube – 365nm Black Light

Description

The QTX 18W T8 fluorescent UV tube is a 600mm (2ft) black light tube emitting ultraviolet at 365nm with an output of 80W/cm. The tube has a standard 26mm diameter T8 profile and fits any compatible fluorescent fitting with G13 bi-pin connectors.

Suited to stage lighting for UV-reactive props and costumes, small entertainment venues, and banknote verification systems, the tube provides consistent UV output across its full length. The 600mm format works in compact installations where space limits the use of longer tubes. The 18W rating draws less power than equivalent 36W or 58W tubes while maintaining sufficient UV intensity for small to medium spaces.

The 365nm wavelength sits in the UVA range, causing fluorescent materials to glow without producing visible purple light or excessive ozone. The black glass coating filters out most visible spectrum light, leaving only the ultraviolet output. The tube operates on standard
