This UV-C light has 2 REAL UV-C mercury bulbs, NOT LEDs. That's important to know because current hand-held UV-C LED wands are pretty much ineffective at killing even the weakest of germs (they are barely within the germicidal light spectrum (expensive LEDs may be much better, though). What is in question is how effective this little 3 watt hand-held UV-C lamp is. It's germ-killing potential has to do with its light output and time exposed- the more the better for killing germs and viruses. For toilet mounted disinfection, the unit has a built-in auto switch that is "suposed to" allow it to be on only when in a horizontile (lid down) position and shuts off when at 30º or greater, but mine is a bit too sensitive for hand-help operation and turns the light off-on if moved in less than 30º positions. The main ON-OFF button also turns red while charging and green when fully charged. The unit beeps twice when you turn it on to let you know it's about to turn on. It automatically shuts off after 5 minutes and beeps when it either auto shuts off or when turned off manually. The ad for this lamp claims to also have ozone between .01-.05ppm density which may not do much in an open environment. Ozone is a gas and a pollutant that kills microorganisms in a closed environment, like a room or even a toilet. You can usually smell ozone and the majority of it MUST be vented before you can safely be in that space again. However, with this lamp, I don't smell anything. Even so, no matter how low power this lamp is, you should NEVER look at the bulbs when it's on and do not allow your exposed skin near it. It is VERY dangerous in several ways to humans, animals and plantlife. I will be using this UV-C lamp to disinfect guitars that I fix and other small items. I hope this helps.

Very good item for the pandemic and gives off legitimate UV-C germicidal light! Two authentic lights that kill germs for under $20 is a great deal and they are small enough to carry i. your pocket!

Az UV fény nagyon gyenge. Nem sterilizál semmit azonban még mindig működik, mivel valójában UV-C. Azt kapod, amiért fizetsz

The UV light is very very weak .. will not sterilize anything however it still works since it is actually UV- C. you get what you pay for
