Easy-to-Use, Battery Powered LED UV-C Lamp - Hold for 30 seconds for effective Sanitation

Disinfects Surfaces, Kills COVID-19
and More

The LCNDT ST-100 UV-C 275nm Disinfectant UV Lamp uses UV-C technology to disinfect surfaces and kill pathogens like viruses and bacteria, including SARS-CoV-2, the virus that causes COVID-19. UV-C is the traditional form of Germicidal UV light, which has been used by scientists for more than a century to reliably destroy and deactivate all kinds of pathogens like viruses, bacteria, mold and fungus. UV-C works by damaging molecules like nucleic acids and proteins, making the germ incapable of reproduction - the higher the dose applied to the area, the more effective the UV-C light is at doing that. See below for proper usage and additional notes.

*Note: UV-C is hazardous to skin and eyes. As such, the ST-100 is not a toy and should be kept away from children.

*Only aim the ST-100 at inert objects, and NEVER at animals or people.

*The ST-100 is designed to be used as a supplement to other cleaning methods.

*See below for a list of additional recommended safety precautions.


Usage and Application:

Adjusting the Dose Amount of UV-C Light:

Use the following guidelines to appropriately adjust the amount of UV-C exposure for your applications

  1. Intensity - start with the intensity of the lamp - ST-100 is a 40W LED which is very bright as compared to many other UV-C lamps.
  2. Distance - the closer the lamp is to the object, the higher the dose of UV-C light. At 8", the dose is 1/4 of the dose at 4". This is called the inverse square law. The tradeoff is that at 4", you will have a smaller illuminated area.
  3. Time - double the time, double the dose

 Recommended Exposure Time and Distance:

  • Time - The longer the better. The laboratory that tested the lamp listed a 99.9% kill ratio in 10 seconds on the types of bacteria listed (see attached lab report).
  • Distance - The manufacturer of the ST-100 states that 30 seconds at 4" kills most bacteria and viruses.

Safety Precautions:

UV-C is hazardous to human skin and eyes. The following guidelines must be followed to protect yourself from serious damage:

  • Wear UV filtering safety glasses (safety glasses are included)
  • Avoid exposure to eyes - Never look directly at the beam
  • Avoid exposure to skin - cover your arms, hands and other extremities


The LCNDT ST-100 is not a toy, keep it away from children. Only aim the ST-100 at inert objects, and NEVER at animals or people.
