[@LeifNelandDk]

I wonder what would happen if every knowledgeable buyer measured the battery capacity and gave a one star rating and a bad review with the real capacity?

[@MIKIVELES369]

For every knowledgeable buyer there are 1.000 byers who will give 5 stars as soon as the lights turn on. That's why we have sellers marketing 5.800 mah and more. That one review will decrease the overall rating only by 0,004 %

I would bypass the mode controller and install a physical on/off switch to all the LEDs. All the clicking through modes and flashing is just nonsense.

that is nice but these guys are all about cost. i have a flashlight with a similar switch, now it has an issue with the contacts, hard to get the mode I want

[@Yonatan24]

But the LED's don't connect directly to the battery.

[@jpcvandam]

I did think of the Efteling too, it’s a fairytale themepark in the Netherlands, and that name suits the capacity ratings on those batteries perfect.

[@Lemau]

A bit too expensive for a bit too fake-ish insides? Yeah, that sounds about right. XD

[@ElmerFuddGun]

These flashlight companies would sell way more if you didn't need to switch through a dozen modes to turn it off and on. How many times have you tried to turn these off too fast and flew right by the off state? There should be two buttons; one on/off and another for the mode. Most people will just use their favourite mode and if you are really _exploring_ you likely will want to switch it on and off to save battery power.

[@crackedemerald4930]

That's true, a separate off button would be better

Absolutely ! Just a flashlight. Not strobe , flash , blink , SOS , call Bat man , and everything else.

[@ke6gwf]

Most people don't care about the cyclical modes, because most people are used to them all being that way. When you get one that you don't have to cycle through, it's a surprise and a relief lol I find it very annoying, and spend more to get lights that work properly, but I also buy lights with the cyclical controls if it particularly want that style light, and just cuss it whenever I use it.

[@extrastuff9463]

@@crackedemerald4930 Seperate button or programming that microcontroller so that you'd have multiple actions and mode memory (turns on with the last used one) would make it somewhat more useful for example: normal short press = next mode double click = jump to max output mode (threshold for what is a normal single and double has to be set sane) long press while on = turn light off long press while off = turn on at lowest output mode Oh and flashing modes should be removed or obfuscated at the very least behind something like triple fast click?

[@JerryEricsson]

Back in the 1950's my father, who was a farmer, thought he needed a headlamp for working around our farm. You see we were so far out in the back country of North Dakota that electric power had yet to reach our farm, in fact it still has not although the farm is now vacant and has been absorbed into a huge maxi-farm. So he looked around and found a true head lamp. It consisted of a battery pack that you wore on your belt, the pack held 4 D cells, a wire ran from that to a large light housing with an incandescent bulb, glass lens and tin housing. An elastic band stretched around the head and another over the top. It actually worked OK, Dad said it was a "Miners" light and he wore it when he had to check the cows who were calving late at night, and other chores after dark on the very dark farmstead.

[@seanseoltoir]

I would have thought that around that time, the miners would have been using the calcium carbide head lamps. Calcium carbide plus water equals acetylene which burns very readily.

[@phils4634]

Soshine NiMh cells are remarkably good quality for the money. Not yet in the same league as Eneloops but they offer a very good capacity per dollar spent (and seem to hold charge very well).

[@pileofstuff]

I wonder if that extra strap length would be enough to allow it to be worn over a hard hat? The contractors I work with tend toward Petzl lights because they fit well (and securely) on their hard hats. And at the same time they regularly grumble about the cost of the Petzl lights...

[@bigclivedotcom]

The Petzl lights are designed for use on hard hats, but the quality is poor for the cost. My first LED head light was a Petzl Tikka. The dollar store clones are actually better made.

[@mysock351C]

Youd have to do it out of circuit to get an accurate reading, of course. You could short your meter leads together and read the nominal resistance and subtract it from the reading if the meter is stable enough (i.e. doesn't jump around a lot).

[@mysock351C]

@Alan Hartley Its called a Kelvin connection.

Yes that's true. Are you sure subscribe to popular Electronics many years ago. I built the Precision 1 amp current injector project for this reason. It still may be around somewhere in my stuff somewhere not sure though. I'm sure somewhere someone could find a project on the internet I bet. If so desired. They should have an archive would be nice. Another possible source for a project would be the Encyclopedia of electronics circuits? And Cookbook of electronics circuits? Sorry cannot remember exact titles. I have only one volume so couldn't tell you for sure.

[@rtesimpson]

[@michaelthibault7930]

I wonder when someone of Clive's height, build, disposition, and inclination will be so bold as to begin suggesting ways in which products torn-down could, or can, be improved from stock. In the case of this head-lamp, would it have been worthwhile, for example, to bin the batts and replace them with something more burly? Could the silliness of the lockstep switching cycle be changed --arguably 'improved' -- by excising a few LEDs so that point in the cycle effectively, if not clicked-through, turns the unit _off_ and resets the cycle to the default start? Etc..

[@williamarmstrong7199]

Thanks for looking at this Clive. I have several set of similar lights / torches and use them a lot in the winter when walking the dog and another set which has cob arrays either side of an adjustable beam led when I am servicing the car. Its great to illuminate the deeper darker parts of an engine. :)

[@tomarnd8724]

My favourite uses a single focussed LED in a very rugged housing with a simple on/off function and adjustable intensity that is retained in memory.

[@wwsxa39]

Mine is also a simple on/off, but is more of a flood than a spot. I find it easier on the eyes.

[@ymmvcouk]

Mine is from earlier in the pissing match, when there were only 3 LEDs. Some wet+dry to two of the (plastic) lenses turned it from spot/spot/spot to spot/flood/spot+flood (and strobe) and it's been great for work and play for three years now - well worth eight quid and ten minutes effort!

[@SodaAnt]

@Garaidh Llwyd That's not how LED screens work. They are LCD screens with an LED backlight, usually a few dozen LEDs at most.

[@extrastuff9463]

@@SodaAnt Well I guess there are OLED monitors out there now and AMOLED screens for phones/tablets nowadays, in which case the screen does consist out of many active light emitting elements instead of an LCD letting light pass or not. But they do have known issues with the blue pixels degrading faster than the red and green ones, possibly leading to colour shifts later after use. And I suppose if one is used 24/7 with rather static images that have bright sections displayed they can kinda similar to old "screen burn in" but in reverse dim that area earlier than expected.

[@JerryEricsson]

@@extrastuff9463 The early OLED screens do fail with age. I had an old OLED watch that I used to love, I could watch videos on the blasted little screen besides it being a rather large, very heavy due to it's all pot metal case, and had extra batteries that one could charge individually as needed. After about 3 years, the screen went dull then went so dim it barly showed, that's when I took the batteries and used elsewhere and tossed the watch. Hated to see it go, it was a neat item, it was also a cell phone but now days that seems the norm and not the exception. I also have an old Archos 104 where the OLED screen has gone bad, it now displays in a dim RED and black mode that can only be read in the dark. Works OK for a night time MP3 player to lull one to sleep and keep the nightmares at bay player, well it did till very recently when the old battery began giving up the ghost, now only plays about 2 hours then dies. Time to that one to go in the bin as well I guess. It was only a 4 gig anyhow, and by today's standard, mostly useless, however I have never tried to listen to more then 4 gig of music in one setting anyhow.

I have the single unit LED torch that you tested a while back. It had a small round hole for a charging lead but no circuit to control the charge. I removed the battery holders and found enough space beneath to fit a TP4056 charging board. Filed out the round hold to fit a micro USB plug on the TP4056 and the original LED hole lined up to show the red LED on the TP4056. Fitted 2 decent Samsung batteries and it gets a really good run time and easily recharged. Shame about the heat it produces though. Does get quite toasty after a while.

[@davidb5255]

I bought an 8 LED lamp, with all LEDs arranged within one round multi element reflector. It's primarily a bike light but has a head torch strap. Stupidly bright on full beam, turning night into day, lasts < 30mins on the crappy 4x18650 cells it came with but gets so hot you can't touch it!

About 8 weeks back my first headlight arrived from China. I had selected the 3 LED version and it is quite fine for my purposes. I am getting old, you see, and my eyesight is getting a bit "dim" if you will. So when it comes to soldering and such, the lamp beside my chair is just not good enough. I used to have a small USB LED thing with a clip that I would attach to my clothing and plug into a nearby power supply but the clip broke off and I could no longer find it on Ebay (perhaps I didn't search good enough.) When I was last at my dentist, they were using headlights with a single LED and it seemed to be great for them, so when I saw the one on Ebay with 3, why that should be 3 times better right? Well not really but it does the job nicely for me. Thanks to being a long time Big Clive watcher, I was wise enough not to order the high capacity batteries, since I have a large supply of 18650's taken from old laptop batteries to use. When it arrived I found it to be just what I needed, and I use it on at least a weekly basis. It puts me back in the "lets try to build.....) mode! Yay, you only stay young if you learn one new thing every day, and thanks to Big Clive and a few other KZbinrs, my learning continues daily. Folks just do not understand how an old disabled cop like myself can stay so young when they know I have always been older then they are.

[@TheNiteNinja19]

I got one from Newegg for cheap. Says it came with 4000mAh 18650 cells. After testing they were 500. So I use those in my pocket flashlight and put my actual EBL 3,000mAh ones in the headlamp. Headlamp lasts weeks now since it's a single focused diode with 6000mAh behind it. I find these things handy.

[@Addixxtion]

A few things I would note having been an avid vaper for some time now. 1. Discard the chinesium batteries ASAP! 2. Buy a proper set of 18650's from a reputable company (Samsung 25r, 30q) 3. NEVER charge cells inside the light, always charge using an external charger. 4. Check out Battery Mooch for listings and tests of 18650's and their true ratings. Lastly, I've seen reports of these blowing up on people's heads, almost certainly down to the house fire brand batteries.

[@phils4634]

TrustFire - you can trust that they'll catch on fire! Unusual honesty in Chinese advertising! ;-)

[@mysock351C]

Im guessing the resistors are there because there are three LEDs in parallel for the primary circuit as opposed to two in the auxiliary circuits, possibly to limit the power dissipation in the transistor.

[@joradcliffe565]

If had this type of headlamp then would be thinking of bridging out resistors at least temporarily to see if made much of a difference

[@aaronbrandenburg2441]

Question here. And more. Will that run straight off the USB port without batteries installed. being supplied all current through the charge cable through the port. And or and just running it without draining batteries. Also I am looking to modify I a headlamp that uses three Double A's or three Triple A's. to run off either the internal battery. pack with a modification in the middle of the cable. Either or install a small barrel Jack somewhere there's enough space available to do so. So that be able to use USB power. through an extension or an adapter jack. To run off a power bank in an emergency situation. if the power goes out in your low on batteries. Also I found that that server image LED Lantern. the large one with a DC Barrel Jack and the on off dimmer switch. Even though the red voltage is 6 volts for both D size batteries. and also the adapter jack as external worse excellent through USB power. through a cable that fits the adapter jack. I have run off a power bank before. Also I happen to have a cable for another device that's power only no data pins connected of course. That handle problems Barrel Jack. But I took out the rubber plug assembly for the the adapter jack. so that could plug it in properly due to the fact it was a a barrel plug it was too short to fully plug-in otherwise. Also I was looking into a headlamp that uses 18650 cells. 1 of them? That can also if you don't have the available or are they are dead. Can run off 2 lithium camera cells. Which if I'm not mistaken are now available rechargeable form..

[@aaronbrandenburg2441]

PS. has anyone converted Warehouse Harbor Freight cob work light flashlights. The frebe ones that is. There are actually surprisingly good lights for the money. even if you paid the full retail price would be worth it. the ones with the three LEDs on the front end and I called light on the front where the switch is.

The Microchip PIC16F18313-I/SN would be a nice replacement for that microcontroller. You could use PWM to control the brightness of the LEDs if you want all on but at lower intensity to reduce harsh shadows. Less than £0.60 from Farnell in one off pricing. I would definitely put some series resistance with the LEDs otherwise they're just going to cook without significant increase in luminosity as they will run at very poor efficiency also resulting in low battery life.

[@ethanpoole3443]

“Field Effect” is what is actually performing the switching in a FET. The actual electron field at the gate is what switches the transistor on (or in a special case, off). There is no actual current flowing through the gate like there is with a traditional bipolar transistor’s base, it is literally the presence of absence of the electron field itself that makes the path between source and drain conductive (or insulating in that special case).

Hey Clive, for a long time I have been envious of your Poundland proximity. Guess what? Today I went to town, this is a ferry and then a bus and took 1½ hrs. Where Woolworths had been, then overpriced outdoor garment .co, then Dealz (same as poundland) and now today there is a Poundand :) I rushed in and bought a £1 power-bank, not because I need one one but because you showed me the inarrds. (It's been charging for 2hrs. but still flashing, is that duff?)

[@ValleyRC]

I have a friend with one similar to this and the light it puts out is pretty awe inspiring. In terms of pure light output it's amazing for the price. Not sure about longevity though. Chinese stuff does surprise me sometimes though.

[@goodun6081]

Hey Clive, how about a teardown/review of head-worn magnifying visors, presumably including various cheap modern ones with plastic lenses and LED lighting built in? I've got a couple of cheapos that sell for 10 bucks or less at the Job Lot store. Plastic lenses, and the LED lights on either side of the lenses are merely okay, somewhat bluish light spectrum. And the magnifying lenses are plastic of course, and you have to flip down or pivot extra lenses in front of the main ones in order to achieve higher magnification. And then I have three of the much higher quality, significantly more expensive, glass-lensed Opti-Visors, outfitted with 5, 7, and 10 diopter lenses..... but they don't come with built-in lighting, and the Maglite style halogen bulb add-on lighting unit that Opti-vizor sells is overpriced and performs poorly......

So who *does* sell good, protected 18650s for use in flashlights and such?

Josh Tolbert you just have to find trust worthy sellers I’ve had good luck with mountain electronics, vesture_of_blood, and optics outlet on eBay

Orbotron is a good source for higher capacity protected 18650s, but you will pay more buying a trusted brand but then they do actually deliver on their claimed specifications.

Heh, I bought some elfeland "1200 mA" 14500 cells for a flashlight (knowing full well they weren't). They were ~350 mA. I tend to assume the actual capacity of any Ebay batteries is ~~ 1/5 of the rated claim. That tends to hold true, in my experience.

At 12:26, concerning the resistor marked 101, 1 is *not* a "multiplier", because 10 times 1 equals 10! It tells you to add a single zero to the 10 proceeding it, thereby signifying a hundred ohms. People might refer to this as a *multiplier*, but it isn't. Yes, I am being pedantic.

[@purpleviolin]

It isn't 'adding zero' (10+0=10) and is actually multiplication but by 10 to the power of the number '101' = 10x10, '102' = 10x100. Multiplier is correct but assumes you know about powers of 10.

[@purpleviolin]

@Matt Quinn yes correct 😂. My phone seems to be working against me and regardless of how I type, it seems to deliberately screw with the spellings. Thanks.

[@ethanpoole3443]

The final “1” in “101” is indeed the multiplier position as it what *defines* your multiplier even though the actual value is an exponent, it’s just that you multiply by 10^1. That knowledge is considered a given if you work with electronics.

I can proofread a post prior to posting it, and then I look at it again after it has been posted and realize that words have been changed. I usually use the voice to text feature, speaking into the phone and having it transcribe for me, and sometimes several seconds after it types the word I have spoken, the word will change. I've also noticed that if I use any expression of speech that could be interpreted as the title of a song or movie, the software will capitalize the entire phrase.

@@ethanpoole3443 , I actually repair audio equipment fulltime for a living, so I do work with electronics. You could say that we are both at least partially correct, and I do understand about powers of ten; however, where people get into trouble or where it gets confusing is that you will see capacitors and other components that have three numbers on them that are the actual value of the component. Older ceramic capacitors will often be marked directly with the picofarad value of the part, although sometimes they're marked with the power of 10 multiplier scheme (and generally, ceramic caps will graduate to a decimal or fractional microfarad rating at some point, like .0047 or even .00047) . I've also seen small film caps that are marked with the actual value capacitance (or trim- pots marked with the actual resistance value); sometimes 470 means 47, and sometimes it means 470! When in doubt, grap the capacitance meter. It really is a stupid system. I'd almost prefer capacitors be marked with color bands like resistors, except that nowadays, modern resistors use such tiny narrow bands of somewhat odd color- spectrum markings that it can be difficult to tell red from brown, especially after the components age or are exposed to heat ( my eyes are also aged, and have probably been exposed to too much heat!). And now that 1% and 2% tolerance resistors are common, sometimes it's hard to tell which end of the resistor is which!

After seeing your review, I might actually buy one of these, $12 and it comes with (cheap) batteries, that's a pretty good deal I think, plus the cells are replaceable, very handy when you have other things that take 18650 cells (vapes and other flashlights) and have a bunch laying around.

[@paulstubbs7678]

Thanks for the review of another crappy torch, I love how they just connect the LED's straight across the battery with no proper current control. I was appalled when I saw this done using 3 x AAA cells, I thought they would get it right when they moved to Li-Po batteries. That's probably another reason for supplying low capacity shitty cells, If they used good cells the LED's would immediately blow. I tried fitting Ni-Cad cells to one of those cheap 3xAAA cell torches to see what would happen if you used batteries that would not collapse/load down, Bang/fut went the LED's

[@jeffreyhebert5604]

one more question for us nerds long but decisive...do electrons flow from pos to neg or the opposite....this isnt my question and why Im so confused...how does doping make diodsn etc make shit work..confused in california..cheers i

[@ethanpoole3443]

Electrons are sourced from the negative terminal (recall that electrons carry the negative charge). The terms “positive” and “negative” potential were coined before we had discovered the electron and electron theory, hence the disconnect in which direction things flow, so the positive ultimately receives the negative electrons once the circuit is completed.
