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 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.

Merry Christmas Clive. Glad your feeling well enough to make a video. I recently saw some very small LED lights on a pre-lit tree at a local store. The LEDs were the size of a small grain of rice, very nice.

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

I just repaired a 2 wire set with 7 modes that had been cut by a lawnmower. I measured 28V AC on a multimeter. I found that most unusual for an LED string. But there was no DC component whatsoever. I was running low on time, so I didn't take the time to put it on an O-scope. It was a super simple repair. I soldered the wires back together and coated them with an ample amount of dielectric grease. Then 2 layers of heat shrink. 1 for each wire with the grease squeezed inside, and then another over the two together to strengthen the repair point.

@bigclive feel better soon!

Thanks from Texas Clive.

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...

@AdityaMehendale

@@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 :)

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... :(

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.

I added a set to an online order. Hopefully they still have them in stock.

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.

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.

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.)

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.

Get well soon Clive!

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).

"No, I'm not hoarding Christmas lights! Give them back!"...

I've just bought the same rope light set from Aldi and it came with a remote control also has a timer cost me a 10er 😀

That 3 wire business makes sense now ....cheers

Tip - if you your white lights are too boring you can colour in the bulbs with sharpie pens. More colours than your usual blue red green yellow too.

You say “that would be hoarding lights” like it’s a bad thing. Those are indeed some very attractive LEDs, and are very hoardable. Hoard away Clive, hoard away.

How love it you could cover 120/240 LED strings. Seems like the first bulb is different than the rest of the section, some have fuses, etc...

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 seem to remember the AC powered DC string I have being a set of series strings in parallel. One of the wires got chopped off by a closing window and I think it only went dark from one or two LEDs in front of the cut. Now I might have it mixed up in my head from all the hours spent shifting bulbs around in the old incandescent one to eliminate the broken ones from last year - that one for sure had them in series sections.

The 32V sets tend to have ten parallel section in series. It is possible to knock out a section of one of those parallel circuits.

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?

I also repaired one of those all parallel strings which got some LEDs crushed, also by a car. Also I think those parallels-series strings are driven at constant current not constant voltage.

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.

I just get an old USB cable and solder it inside the battery box with some little resistor (choose resistance calculating on how much batteries the set requiers). You can even solder to the switch (if it has two positions) so you can choose between batteries and USB dynamically. This season I added USB feature to 3 of those sets

Getting those copper wire LED stings into some of tube is a pain. After many attempts using different methods, I managed to suck a thin bit of cotton trough a one meter tube.
