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
UV led specification
UV led circuit
Calculate series resistance for single LED resistor
Calculate series resistor power rating
Calculate series resitance for multiple LED resistor
Calculate series resitoir power rating
Series resistor colour code
Wiring with a choc bloc
Wiring with Wago 222 connectors
Stuff that glows

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!
Good fundamental explanation of how to use LED's in circuits.
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
Thank you sir to give us this information which will be helpful for project
Awesome and very clear explanation. Don't understand why some people did not like it. Nothing wrong IMO.
Excellent video ... clear and very to the point
Awesome video! thanks!
thx, I learned something...
awesome, thank you so much!
you are the best of the best. Really.
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.
Brilliant thanks 👍
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.
Nice!!
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 🙏🏻
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
+Danijel Kulenović In my experience they do still have a purple glow, I think what you might need is a fluorescent black light bulb or you might be able to filter the visible light from the led source.
Hello, thanx for fast and kind answer. Any ideas on how to filter? I guess i would need some kind of folium i dont even know where to look
I don't know sorry.
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?
You need one resistor for each series string of LEDs. There are online calculators which will work it out for you as well.
@@techydiy Found it, tkank you !
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 👍👍
An hour or so at a guess
techydiy could there be a small battery that would last about 8 hrs
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
If you aim to eradicate most of the microbiological organisms you need to usea light source with 254nm wavelength (Kowalski, W. (2009). Ultraviolet Germicidal Irradiation Handbook). The light density will determine the duration you need for near complete annihilation (99,99%). Nowadays pulsed xenon lights are being used.
Is UVA light dangerous or safe to use?
Can I use 15V battery for 5mm led?
What's the sfecific use a UV led ?
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 🙄
The Usb voltage output is 5v, find out what voltage and current the led needs and then do the maths
can it be used to kill bacteria? like a UV lamp
hmmmmmmm ! i just wanna go hearin aid battery - led ,,, ie no resistor is this atal possible ? pleeeeeeeease :)
Yes you can usually connect a small 3v button cell battery directly to an led
can you please contact me ? i'd like to string 10 5mm and need to know how i cn power it by battery and by 110/220v
There are online led calculators. Available. You should avoid directly powering LEDs with 110/220v as this has the potential to be lethal. A wall wart to drop the voltage to a safe level is the way to go.
If 4 UV LEDs Connected in Series and it is Powered by a 12 Volt Battery, then, Without connecting to any Resistance, will the Series of UV LEDs work without causing any Damages..? Kindly guide me...
It depends on the internal resistance of the battery. In general you should include a resistor to limit the current. The correct approach is to use 3 leds and an appropriate resistor.
@@techydiy Thank You So Much
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
👍👍🇩🇿🇩🇿
i felt like in the class and felt a sleep.
