In this video I give some information about UV (Ultraviolet) Led Wavelength, How to calculate the series resistor value, some simple ways to wire or connect them and then look at a few items that glow under ultraviolet light

I really liked how you walked us through the application of Ohm's law here.

[markg]

Thank you! I really have a much better understanding now.



I'm surprised it didn't seem to matter where the resistor is located in the chain. Thanks again!

[JohnClulow]

Good fundamental explanation of how to use LED's in circuits.

[JuanLopez-zkro]

Awesome and very clear explanation. Don't understand why some people did not like it. Nothing wrong IMO.

[zaeamos]

I was expecting layman but this was definitely professional. However your audio needs improvement. Your left and right non-mono needs correcting. See 1:20 to 1:34

Nice! Good clear and down to earth tutorial I'll be ordering 10mm thought their voltage would be higher than a 5mm thx very much

[eberhardmuller]

Excellent video ... clear and very to the point

[rutviksolanki]

Thank you sir to give us this information which will be helpful for project

[bernardmcnamara]

Thanks mate.
It seems to look basically simple & straight forward.
All this friging around just to get a strong powerful distance 254nm short wave flashlight/tauch.
365nm Long wavelength straight of the self.
But a 35 + wattage 254nm short wavelength UV light.
There just not out there. On the shelf.

which created the better "glow?" just looking for mild ambiance with hidden lights and to react with glow in the dark paint only visible in the uv.

Hi! Could you make a video to build a led strip? one of those that are used to decorate Christmas trees but using UV LEDs
Thanks 🙏🏻

[taffythegreat]

How long would the battery last, if you wired up the uv led to a watch type battery, if it was on continuously ?
Very clear video 👍👍

[MrSigitasM]

Really informative, thank you. Im beginner. What if I have 100 UV LEDs. one resistor would not be enough right ? should I put them in rows with a few resistors or something?

[booonnoob]

Is UVA light dangerous or safe to use?

[bastamanibrahim]

What's the sfecific use a UV led ?

[danijelkulenovic]

Hello! First of all congratulations for such a wonderful video that explains uv leds.

Now I have a question and would very much appreciate if you could answer. I have seen on some sites (ebay etc) that there are UV 275nm led (UV-C) so I was wandering if these led's would be less "purplish" since they are further away on uv spectrum and also would light that they emit still activate fluorescent things? I am asking that because I would like to have an UV source that would be practically invisible but still emit light that would activate fluorescent stuff

I want to have a 254nm wavelength for my experiment. Can I do it with led lights or I must find a lamp. Why they use 254 with lamp and not 285 with led lights? Thanks again

[rickyrsyahputra]

can it be used to kill bacteria? like a UV lamp

[linkmasters]

Yeah I'm trying to do a project with UV LED light powered by a male USB port on on my laptop the led is 5mm 350mcd 20 degree beam I was wondering if a 100 ohm resister on the positive side of the LED plug in a laptop USB port on the side will work for me and I cut a 6 inch male USB to a mini USB male port mini side off and striped all the wires off and just left the red and black wire only and the long side of the led solder to the 100 ohm resister and to the red wire and the short Side of the led straight to the black wire but I don't know if this will work for me and not blow out the UV LED light 🙄
