Will this light work to kill bacteria in water?

Hello William. The short answer is unfortunately no. The optimum wavelength for killing bacteria is around 260 nm. Our flashlight produces light at 395 nm which is optimum for making certain materials fluoresce or glow. To sterilize water you would need to purchase a device specially made for that purpose. I hope this answer helped.

I found this light to be pretty much useless except for freshly dried urine on fabrics only. Maybe buy yellow filter glasses might help. Not what you think it will do

Lights such as these are used in food processing with quality control microbe detection systems. I have practical experience in this. I would recommend the water be contained in a transparent container and exposure should be no more than 1.5 inches to the depth you desire. Theoritically, you could have a 3 inch diameter container and move the light the circumference of the container holding the light in position for minimum of 5 minutes on each side. Yes this will destroy microbes present in water that the light hits, but the microbes must have enough exposure. Brush up on UVC wavelength vs microbes and qualitative analysis is recommended for best and safest results. Be well.

I can't see why not. It's a pretty cool light, if it works, but in reading the reviews, it's unpredictable. Mine filled with water after a day or so.

This light is for a Marine (Saltwater) setup. TrueLumen makes a freshwater LED light also, just check out their website for the details!

It will kill/reduce most forms of aerobic bacteria in a reasonably clean water system. If you have high concentration of bacteria, you should treat with a higher concentration oh H2O2, and maintain the water system with this.

The light kills bacteria so I would say yes. I haven't done it myself but I've used it to deodorize plastics and rubber grips so I imagine you can use it on shoes. Because of the soft absorbent material I would presume you'll have to leave the light sit on each shoe for a couple of minutes. Longer than suggested.

I just got this at Christmas, but my understanding is that it works indefinitely. The light is actually powered by the water, so it should work for a long time.

If you want the light to work, yes. Filtration would also be a good option in a tank this small, if its possible.

NO! Do not use in shower or around water. There are 3 AAA batteries inside the Dot light.

I have the light on the bottom of a 10 gallon tank . And it is works great . It is waterproof for the six inches or so that is submerged. I hope this helps.

I don't think this light would be bright enough for a salt water tank. I have mine on a 75 gal. fresh water tank and I like it. Salt water tank I don't think so.

The battery compartment is not water and moisture proof. I have not had luck with this light. I am using it in my laundry room as a turn on light , the sensor does not work on the one I have.

The light emitted does not illuminate very far, only a few inches. As long as the lines are void of fluid, short, and not very sharp turns/curves, this might work for you.

Yes absolutely. Since the led light stick is not submersible it can light either fresh water as well as marine. For planted aquariums I find that just one stick/strip supplies more than enough light to keep hardy green plants healthy and happy. I love this light!

You run the hose that is currently going to your drinking water faucet through this UV light filter and it kills all the bacteria in the water. Easy to install, works great.

Glofish website suggests using blue LED lighting, so I assume this fits the bill. However, I can't say for sure if this will work best, for I use it to light my FOWLR tank. Sorry can't help you much. It is a very cheap system (light+power supply), won't set you back at all.
