  • Internal ballast enables plug-and-play replacement of traditional lamps
  • Microwave sensor halts operation instantly when movement is detected
  • 10-second delayed start with audible alert allows safe room evacuation
  • Multi-angle pin adjustment fits U18 T8 fixtures without rewiring

Germicidal UV-C tube for occupied spaces

The Jaspertronics U18-040W-01 is a 40W T8 lamp emitting 254nm ultraviolet light for surface and air disinfection. An internal ballast allows direct replacement of existing fluorescent tubes in offices, schools, healthcare settings and homes. A built-in microwave sensor halts operation instantly when movement is detected, protecting people and pets from UV exposure.

Sustained output with sensor-gated duty cycle

The lamp delivers 70w/cm2 intensity at 1 meter while the sensor confirms the area remains clear. A mandatory 10-second delay with audible buzzer precedes each start-up, preventing accidental activation. Output remains stable for as long as the space stays unoccupied, making it suited to scheduled disinfection cycles in laboratories, retail areas or hotel rooms rather than continuous unattended operation.

Low-heat quartz envelope, mains-voltage operation

The ultraviolet quartz glass envelope runs at typical fluorescent-tube temperatures, adding minimal thermal load to standard ceiling fixtures. Power draw is 40W across 120V or 230V supplies with no external ballast losses. Silent electronic operation and the absence of moving parts keep acoustic impact negligible during the disinfection period.

Questions about this item

How much power does the 40W U18 T8 UV-C tube draw when it runs continuously?

The lamp is rated at 40W and operates on 120V or 230V mains supply with its built-in ballast.

What fixture or wiring must I already have to install this U18 T8 UV-C tube?

It fits a standard T8 socket and works on 120V or 230V mains; the internal ballast means no external gear is required.

Will the microwave sensor on this 254nm UV-C tube interfere with older T8 ballasts in the same circuit?

The sensor only controls the tube it is built into; it does not send signals that affect other ballasts on the circuit.
