A teardown and schematic of a very simple RGB colour selectable LED neon-like effect that operates directly at mains voltages.
The use of high voltage means that for a given current you can run a lot of the material. The main limitation will be the internal buss wires and their spike based connections.
The video also shows how offcuts can be used with the addition of just four diodes as a fixed colour strip pre-wired for red, green, blue, cyan, magenta, yellow or white. Noting that the white isn't a nice white and will also reduce the lifespan of the strip thermally.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

What are the differences for creating a custom LED neon strip between an RGB and a single color?
I've had a few where red green are reversed.
Love this episode, simple illustration of the rectifier
does it give enough light for a hallway or stairwell situation, like hidden by moulding for indirect lighting at night?
The colour designations are printed on the LED strip for RGB. Also, I can't remember for sure how I remedied the issue of solder not sticking (it's been over three years), but I think it was wiping the bare wires with alcohol. I'm wondering if they insulate the wires with dielectric grease in addition to the cheap vinyl.
Would adding filter capacitor behind the rectifier help with flicker?
green black orange I guess? Looks green black red on my screen.
It's the color of the sucker and eating at the end
If you accidentally knocked over somones bridge and you told them you were going to make it right and rebuild the bridge would you be a bridge rectifier?
Why do you need a bridge rectifier for these given they're LED's? What would happen if you connected it straight across the mains?
Is the reverse voltage too high for the LED's to handle?
I've also seen some circuits with a single LED and resistor on the mains, some with a diode, some without. Again, I wouldn't think you'd need a diode so I'm not sure what purpose it provides.
I have take 50 or so 1W white LED's, put them in series through a bridge and Cap running directly off the 120V mains…Works like a champ.
The fuse isn't really on the neutral though, i mean, looking at the colour coded cables, it is, but depending on which plug you use it doesn't really make a difference since schuko plugs for example don't have reverse polarity protection.
Hey Clive, do you have a mains power 220v LED 'neon' that you would recommend that's good quality?
Interesting setup very intriguing 🤔

You can see the pulse modulation best with the blue leds
Great video 👍👌 @BigCliveDotCom
Hmm, lovely quality cable and plug, I guess I'd recommend something of better quality :p
