QTX 4W 135mm UV Mini Tube F4 T5 BLB – Black Light

Description

The QTX 4W UV mini tube is a 135mm compact black light source in the F4 T5 BLB format, designed for handheld currency checkers, portable inspection units and small-scale UV applications where space is limited. The tube measures 135mm long by 16mm diameter and emits ultraviolet radiation at 365nm with an output of 80W/cm.

Designed for installation in mini fluorescent fittings with T5 sockets, the tube suits battery-powered handheld devices used for counterfeit note detection, forensic inspection of documents and ID cards, and mineral or fluid trace detection in maintenance work. The compact form factor allows manufacturers and installers to build UV inspection tools into spaces where full-size tubes cannot fit, including portable pest control lamps and small benchtop curing stations.

The F4 T5 BLB designation indicates this is a 4-watt tube using a T5 (16mm diameter) envelope with a black light blue phosphor coating that
