How to fix your low voltage LED Christmas lights

A brief exploration of three styles of wiring used in common low voltage light strings.
These circuits and repairs are only for the low voltage sets of lights that run from battery, solar, USB or plug in power supplies.
Note that for the two/three wire flashing/effects strings the circuitry is similar to the 3-wire strings, but with the LEDs alternating polarity along the string. If rejoining a damaged set then the incorrect polarity of the two LED wires will cause a colour change at that point in the string during flashing effects.
The difference in recording environment is a temporary thing due to catching covid right at the start of a short trip to Glasgow, that has turned into a much longer stay to comply with self isolation times.
I recovered quickly and the lat flow tests strip line faded fast, but I decided to play safe and extend my stay for as long as possible before travelling.

We use a similar strategy in hot water heating systems to balance pressure drop in piping; The top diagram would be called a "direct return" and the bottom diagram would be a "reverse return." Reverse return uses more piping but is easier to balance across many terminals and performs better when some terminals block or bypass flow.

@MrV1NC3N7V3G4 2 года назад

100% off topic here, but your comment reminded me of our disaster of a hot water circulation system for instant hot water that was installed when we built our house...the plumber ran the PEX through the foundation uninsulated and our hot water heater never turned off due to all the heat being lost in the foundation. We had to just unplug the pump and now it's a longer wait for hot water than ever lol!

@throttlebottle5906 2 года назад

@@MrV1NC3N7V3G4 there's models now that only pump when they sense a faucet turned on or by push button, they only run until they sense the hot water at inlet. they're generally mounted under sink and pull from the hot pushing back down the cold pipe. there may be other wireless control systems now that will work with standard recirc setups, who knows.

@Smidge204 2 года назад

@@MrV1NC3N7V3G4 ooof! Always sleeve penetrations through concrete! What you can do to remedy this is a strategy called "demand recirculation." A small pump is put near the bathroom or wherever the hot water will be needed. Before you use the faucet/shower, press a button to activate the pump (some installs connect it to run with the light switch). The pump moves the water from the hot supply pipe back *into* the cold supply pipe, so the cold water is flowing backwards for a few seconds. Once the pump detects that the hot water has finally arrived it shuts off. The cold water may be a little warm for a bit, but the hot water is available right away and nothing goes down the drain. You can buy these systems as a kit that installs under the sink and uses the sink's hot and cold water taps, just need a GFCI outlet for power.

Very informative, The Asda lights I belive are made with the LEDs wire compleate then they run that into the plastic cover machine that form the tube around the lights as its extruded.

@stepheneyles2198 2 года назад

I wonder if the tube is extruded around the LEDs afterwards? If the melting point of the LED wire insulation is higher than the plastic being extruded around them it would be possible to make infinite lengths. (regarding an earlier comment) I don't think they'd spend time threading a wire through the tube then pulling in LED strings, that would be very inefficient...

@GregorydavidMck 2 года назад

My first thought was forced air. Your method makes the most sense as it would seem to be the easiest. I would imagine such extruder setups are the proverbial dime-a-dozen. The cooling would need to be near instantaneous what for to mitigate collapse. Cheers. Thinking always cheers me up.

@willthecat3861 2 года назад

@@GregorydavidMck The easiest way? is to pull them, using a lube. Though, the lighting string seems delicate, and so I think the tubing is probably extruded around the lights too. In principle, I don't see why it couldn't be some kind of thermally processed clear heat shrinking tubing... or the tubing being created around the string by using flat plastic strips that are seam welded (using ultra-sonic welding?) The Chinese do have extrusion machine that might do the extrusion process for the lights. I've seen pictures and specs on them.

The third wire setup is also useful for LED tape on long, unbroken runs, as it too has voltage drop problems, but add in a third wire to balance it out, and it sorts out that issue nicely... :) Also hope you're okay with regards to the lurgy, Amy Macdonald had to cancel her gig at the Hydro in Glasgow last week because of it (and the cockwomble was of the government's inability to handle it!), was rather upsetting to see her in tears over it... :(

If you had no other option than to cut up a 3 wire set you could estimate the resistance of the part you had to cut off and insert a resistor with a close value to keep the total current at a safe value to keep from burning up the remaining LEDs.

@bigclivedotcom 2 года назад

You could add a packer resistor.

@mlenstra 2 года назад

For the less experienced among us: be sure to pay attention to the power dissipation and select the resistor(s) accordingly. A blazing hot resistor among nice and flammable christmas decorations is a nasty fire hazard. Derate the resistor too, as the power rating is for typical open air application on a PCB and not tucked away in some heat shrink tubing.

@elvinhaak 2 года назад

or just include a regulator for the lower voltage. mostly a simple LM7803 with a set-resistor for the voltage will do a fine job (and yes, it will get pretty warm if you took too much of the string off). If you just use a pot for the voltage-setting, you can slowly change the voltage up to the light you like or a bit less to have the remaining lights work longer.

Clever 3-wire arrangement! If you put a ~10-ohm resistor as the "bridge" that you draw at 5:57 - this should be ok - better than just jumpering. I can imagine that most people don't carry a stock of 10ohm resistors and a soldering iron and a shrink-sleeve at X'mas, though...

@jlpicard001 Год назад

How did you determine that 10 ohms was enough to compensate?

@AdityaMehendale Год назад

@@jlpicard001 My guesstimate was based on eyeballing the gauge of wire that is snipped, and the length that needs to be bridged. However, a rough calculation goes like this: The USB-voltage is ~ 5V; The white-LED forward-drop is 3V. This leaves 2V across the "resistor". --> The round-trip-wire-resistance must then be 8 Ohm. BigCliveDotCom cuts the string halfway in the middle. The new string has half as many LEDs, so presumably needs only 125 mA in the new situation (for the same brightness of each LED). In the new situation, the remaining resistance is also halved - so 4 Ohm instead of 8. The forward-drop of the LEDs is still the same - 3V and USB_PB still delivers 5V. The new desired resistance is 2V/125mA --> 16Ohm (whereas the wire provides only 4) --> Add ~ 12 Ohm. :: 10 is almost 12 ;) especially with all other simplifying assumptions.. Hope this helps :)

@rpavlik1 2 года назад

The gadget called "led keeper" works well for mains sets (at least in 120v land). It injects current and bites into the wire with a sharp point to let you "binary search" for the bad LED. No affiliation with them besides happy customer, their incandescent "light keeper" tool is also swell. Keep an eye out for them in after holiday clearance if you're curious but not presently in need. Turns out my main problem in my particular variety of outdoor set is with mainly the blue LEDs failing by a lead breaking off. The plastic caps break off the yellow/orange ones preferentially but they almost never fail, even when accidentally left up all year 😅

@LakeNipissing 2 года назад

One of the problems with C5 LED (cone style) Christmas lights here... squirrels bite the colored plastic bulbs off and bury them in the garden. They are very destructive, and the entire string is trashed because the wires will be bitten in half in many random places and 10 or more random bulbs will be bitten out of the string, and found weeks or months later scattered throughout the yard. I thought this was a bizarre situation until I read about it online and this is a problem lots of people experience (at least here in North America).

@zero0ryn 2 года назад

We have a set of lights where there are 600 LEDs and they are colour changing. Each lamp can be ether warm white or a primary colour or both which gives a lovely pastel effect. You can also select fade from colour to white and back. They have 3 wires but as I can see strobing I suspect uses AC to select between white or primary colour. I tried shortening them with the result of only seeing the blue LED's light dimly. I reconnected the wires and hid the the 300 extra LED's under the sofa.

I've got a set similar to the diagram at 8:00, but every second LED is reverse polarity. The little controller board has different modes which changes the polarity of the voltage at different rates. If the Hz is fast it looks like they're all on, if it's slow, the light appears to 'walk' down the string.

My best guess for how the ropelight could be made is that the light string would be blown through it with compressed air. It's also possible that the tube is extruded around it and the light string is fed through a hollow mandrel. I don't think they're feeding it through by hand. That'd be too fiddly I think.

@TomCee53 2 года назад

I’ve never seen it in strings, but most tape lights are sections of 4 LEDs in series, then the sections are in parallel. For long runs you can feed power from the middle or have a power supply at each end, also giving redundancy. Or for a price run a heavy gauge wire alongside and feed the power at several points. Edit: I’m referring to 12v dc tape lights.

@fonkbadonk5370 2 года назад

A question regarding this: I've been hesitant to start a project that involved ~10m long 5V LED strips (the individually adressable type, which sadly don't exist in 12V versions) because of the uneven brightness issue. I figured that feeding both ends would help this at least enough at those lengths, but would need to use two separate PSUs, one per end, and was not sure if that is a good idea. I would use the same types from the same brand, but were still unsure if this couldn't lead to some sort of issue. Is this a reasonable thing to do? (Running thick cables alongside would not be an option for this project, so also no feed in between.)

@FurrBeard 2 года назад

The LEDs I have similar to yours in plastic tubing have residue from water-based pulling lube.

@chuckthetekkie 2 года назад

It's likely they are using a type of "Heat Shrink" in the rope lights. Also the three wires also acts as a redundancy so if one bulb goes out the rest stay on. Unlike the two wire lights where if one bulb goes out they all go out. At least with incandescent lights. Not sure if the same rules apply with LEDs.

I was somewhat inspired by you this year to make my own string of LED lights, I used colour changing LEDs each with a 180 ohm resistor and twisted together some 7/0.2 wire to wire them all in paralell. I 3D printed a little seperator so the LED wires wouldn't short when you heat-shrinked over the connections and resistor, then 3D printed some christmassy shapes that I glued over the LEDs to make them interesting. I was going to use your LED covers you put on a video ages ago, but in the end spent some time in OpenSCAD designing Christmas trees, parcels, snowmen and Christmas Sloths (long story!) instead. I only made 24 lights in the string but may well extend them for next year, although I only have a small room :D

Hi Clive! A year or two back I watched one of your vids and was inspired to go to Poundland and buy Christmas lights. I bought a string of 50 coloured lights of the two-wire variety and have used them since to drape about my living room at the apposite time of year. They take 3 AA batteries and have two modes, flashing and continuous with an off position, and very fetching they are with their intense colours. The first time I used them (continuous mode) they turned themselves off after a few hours (I thought the batteries had gone flat) but, after fiddling with the switch, came on again, only to go off again hours later. It's apparent that they're meant to do this but there's nothing to indicate so on the box. Tonight, having noticed them come on at 10:18, I was coincidentally awake at 04:18 when they turned themselves off. Six hours fazackerly! How's it done? Happy New Year.

Today I was fixing some multi colour cluster lights. Got them all working but had an issue with a RED LED. If I replaced it with a RED LED the other green or white LEDS in the string stopped work (depending on polarity of the LED). I tried a GREEN LED and they all work!

Forward voltage perhaps?

I once had a cheap set of battery lights but it was 300 lights all in parralel on a 3x AA battery pack and they started off bright and the ones at the end just didn’t work and the ones in the middle where extremely dim as it was loads of leds in parralel just one ciurcit

Christmas lights !The biggest pain in the ass! Give me 120v parallel festoon lighting never mind this series crap .Some times you can't even get replacement led for them .

My main strategy for keeping LED light strings in good working condition is not to buy Chinese garbage. So far it's been worth every extra penny.

back in the 1970s my dad used to put the silver paper from a pk of cigarettes into one of the xmas tree light bulb sockets to make them flash on/off.. 😱

@jammin023 2 года назад

I've acquired a number of light sets this year that appear to be simple 2-wire or 3-wire construction like these, but they have a button on the PSU that selects from 8 patterns of flashing/fading. The LEDs appear to be divided into two groups, alternating along the length of the string. All the LEDs in each group light together at the same intensity, but each group is clearly being controlled independently. But they are not *wired* separately - the same two wires go into each LED no matter which group it's in. So it cant be using separate circuits. Could it be using a simple data signal riding atop the power line? Or is it using some sort of PWM trickery where each LED responds only to alternate peaks? Or something else?

@oldbatwit5102 2 года назад

Could it be that alternate lights are wired the other way round and the polarity is being switched?

@bigclivedotcom 2 года назад

It's swapping polarity to alternate between LEDs.

@pmpwiz 2 года назад

@@bigclivedotcom I never would have thought of alternating polarity! That's why you have a RU-vid channel with 800,000+ subs... and I don't.

@johnwardley7747 2 года назад

Is there a way of disabling the flashing/fading patterns so they are permanently on without having to press the button to cycle through the options? Some sets have a memory that remembers whatever the set was programmed for before it was switched off. But most of mine don't, and they're a real pain! With your genius, Clive, i'm sure you can show us how to intercept the circuitry to lock them permanently on continuously.

@skylined5534 2 года назад

@@johnwardley7747 Thinking back I'm 99% sure Clive did a memory feature hack on the lights you mention but hopefully the man himself can confirm that 🙂

I realise it's not in the scope of this video, but what about addressable RGB LED strips?

They're a specialist subject of their own.

@MrXBT2000 2 года назад

The Chinese origin one I have has all LED chips powered in parallell with a third wire for serial communication going through all of them. That one works as a long shift register. When you send the color values to the first chip, it sends its old ones to the next and so on. If you want to change just one of them, you have to refresh the whole length. I don't remember if the chips waits for the comms line to go quiet before applying the change, so as not light up briefly from the values the are just passing through on such a refresh.

@Killerfin100 2 года назад

Great video mate, I've got some warm white waterfall lights and for some reason yesterday I noticed that half the lights were dim? Any suggestions?

People who live on the Isle of Man don't go to Blackpool lights they visit Big Clives house the display is probably as good.

@alanprest5033 2 года назад

Of course by a judicious choice of power supply from eBay you can make your low voltage set just as unsafe as the mains powered ones.

@vsvnrg3263 2 года назад

how did they get the string of lights inside the outer layer? there are many possibilities. it might have been a big fat outer layer that was heated to plasticity then pulled to length which shrunk it down with the led string inside it. it might have just been done like shrink tubing. all these clever ideas make modern living exciting.

If you have animal and kids breaking the lights it is better to have high voltage ones, they will not do it again.

Clive, I have a set of Lumineo 720 LED Lights Twinkle Multicolour - Type 497507. After 2 years outdoors, maybe 3 sections, short lengths, have "gone out" and I can't quite grasp why! Any insights? Thank you . Mike.

@bigclivedotcom 9 месяцев назад

If they are low voltage then it's common to wire 10 parallel sections in series. Sometimes when an LED fails it goes short circuit and shunts the other LEDs in that parallel section. But you'd normally lose quite a lot of LEDs when that happens.
