Big light, but it's PISH! (With schematic)
HTML-код
- Опубликовано: 2 окт 2024
- An AA (Automobile Association) light that was sent by Robert for our exploration.
The circuitry is minimalist and interesting, the LED mounting and reflector are good, but the battery itself is a bit lacklustre, and the intensity rapidly declines with battery voltage. The choice of a lead-acid battery is odd. If I was being cynical I might ponder whether this was China's way of getting rid of its "toxic" metals.
Still lots of scope for hacking and customisation though.
This is also the video where I realised that the word "PISH" is very "Glasgow". To quote:-
"Pish. Translation: Urine. However, in Glasgow and other parts of Scotland, it's a common word for something that evokes a negative vibe."
This light is "Complete and utter PISH!"

That empty-ish case reminded me of a comic I saw in the 1970s, in _Popular Electronics_ magazine, I think.
This guy is looking at a label on the back of a large speaker 🔊 enclosure which said, _"To avoid the danger of shock, do not open!"_
So what did this guy do? Got out a screwdriver and removed the back panel. Inside were two things: a *TINY* speaker and another sticker which read _"We told you you'd be shocked!"_
You've got a few thumbs Chaplain Dave which means you tickled a few ribs, but I wanted to take the extra time to say thanks for typing up that joke.
lololol!
🤣🤣
Sometimes "searchlight" means that you have to search for the light beam.
haha good one
I remember these "formfactor" lamps from 20 years ago, basically a halogen car headlight bulb with a parabolic reflector and a LA-Battery in a (somewhat) handy format. Lots of Light output compared to other torches at the time, but not the best battery life. Might be fun to hack this thing with a big Lithium-Battery and a ton of LEDs in the front to turn it into the same "portable searchlight" but with much better performance / battery life.
Yes, somewhere I still have one of those halogen based lights. Just like a car headlight, but only for a few minutes. And deep cycling the lead acid battery seriously decreased its life span. Maybe worth digging it out and doing a LED + Li-Ion hack.
It looks very much like the form factor was designed for a filament lamp and updated to use a LED. The reflector would do very little if the light source sends all of its light forwards.
As per everyone else in this thread : I've got one too - again - from about 20 years ago. In those days, if you wanted a powerful torch then they were the only really affordable option. Still works too !!
I loved mine. Still have it somewhere. SUPER bright and focused. From 2004/2005-ish. Handle grip material started getting gooey.
@@pmpwiz that nasty goo can be removed with IPA (Isopropyl Alcohol rather than India Pale Ale) (never tried India Pale Ale on a handle, tho). Apparently dish soap will remove it too. I had to chime in because that goo is a pet peeve.
+1 for Clive to do a supercharged version of this. Seems like something us tinkerers could follow along with!
Maybe something based on scavenged vape batteries? High beam "grill the LED's" mode and low-beam "lasts forever" mode, run through all the calculations for those?
I was thinking that the bulk buyer should sell them as project boxes instead.
,here here to a "top fuel " version 🛸
It looks like it was originally sized for a lantern battery, or designed after an older flashlight that took a lantern battery (alkaline/zinc-carbon, square base, 6V in the US).
The original was. I still have one.
Agree, the design was originally for the 6v lantern battery then the newer ones have gradually become slightly smaller. What gets me is that the light output for many small 2x AA torches is easily much higher than these big cheap lamps.
My daily hack is an Ledlenser P4R Core 200Lumen Rechargeable Torch….. pocket sized but I’d swear it’s at least as good as the old Police baton sized Maglites.
Shine this on yer tonsils on full power? If they’re not red before, they probably will be after.
Actually a great 3 level smooth zoom torch & rechargeable too.
@@dogwalker666 my mom has one of these with the massive lantern batteries. i wonder how hard it would be to convert it using RC car LiPO cells.
@@chubbysumo2230 dead easy, Use a dead battery case as an enclosure hot melt glue does the rest.
I was just thinking it really needs a 4056 charge board and some Li-ion cells hacking into it and you came to the same conclusion Clive. There's a video idea for you, from pish to posh.
Excellent series title: "From Pish........to Posh"
@@matambale I approve it lol
But there is a small problem with this. 4056 is designed to charge a single cell, because it's sensing full charge by measuring current at full voltage, if used on multiple cells or leaky cell, it will be overcharging, you can solve this by putting a resistor in between the charger and battery, but i only did that while i was supervising the thing, i wouldn't rely on that bodge to charge it while i take a sleep.
@@plainedgedsaw1694 I don't think that's true. The TP4056 has a voltage ceiling of 4.2V as I understand and I don't think a lithium cell can be overcharged by a trickle current that doesn't push it beyond 4.2V. A bad cell will heat up, sure. That's why there's a thermal sensor feature built into the 4056 (and disabled in the Chinese boards)
Also needs some AMC7135 LED drivers instead of the resistor
Do it! Add the big battery and show us how to make it a bit less PISH!
100w cob led, HS+fan, as much lithium as you can fit in the box, and custom circuitry ;)
@@Debbiebabe69 More reasonably a 3W led and 10,000 mAh of recycled lithium cells
My dad had a similar looking flashlight 30 years ago with a huge battery taking up the whole body (don't remember what kind of battery it was). With a battery that size and a led light, it would continue to shine long after we are gone😆😆
20 years ago I had one of those hand held spot lights. 1 Million candle power. I had the battery out so thought I would throw it onto my lead acid charger. Came back an hour later to the pore 6v battery bulging to almost twice it’s size. Sizzling and sputtering as it tried to vent the boiling gas. I learned to check voltages more closely that day. Lucky It didn’t explode and spray acid all over my garage.
My dad had one of those back in the day, but it plugged directly into the cigarette plug on the car. Bright as hell, we used to use it to practice archery at night lol
That brings back memories!
Pardon me, but just so I'm clear, you were using a regular _12 V_ car battery charger or similar on a sealed 6 V battery?
And you were more worried about it rupturing to coat your garage than say, for example, your face?
@@igrim4777 I assume it had a converter... It was just common the bright yellow/black lights came with a car jack.
Edit: early morning came across passive aggressive haha. My bad.
@@sparkequinox No passive aggressive noted, so thank you for apology but not needed (maybe you got rid of any before I saw). I just wanted to check I understood your story right because lead acid chargers come in different fixed voltages and a 12 V unit makes your story scarier than a 9 V unit which would be bad enough. Glad it didn't end with damage.
Edit : unless you mean I came across passive aggressive, in which case sorry on my part for that and for being presumptuous in the first part of this comment.
I think this has LOTS of room to hack it, not just with perhaps a more powerful LED but also to stuff it with 18650 (or bigger). It also seems to have room for a bigger heatsink eventually.
I mean the lamp itself as is might be a bit meh, but seems a pretty nifty "platform" to thinker with
The case looks like it was for the old "lantern battery".
It may have originally been designed for that.
@@bigclivedotcom That's the first thing I thought of too.
Would love to see you create a “Clive-approved gargantuan” light one day!
Having once lived in a very rural location, and spent much time in the countryside since I've always been on the lookout for good torches and wasted far too much on cheap ones that are invariably bad, either in the light they provide, the charge they hold or most often both.
For free, it does seem like a pretty good project box for a much better light. Maybe add a swappable fresnel lens when you want more flood and less spot, and swap out the batteries for something else; heck, you could replace the SLA with NiMH and your super-dumb charging circuit, and have an always-topped-up emergency flashlight. And as a bonus, no flashing SOS mode!
Sad about what they actually did with the design, though; maybe they had a pile of otherwise-useless tiny SLA batteries they needed to use up?
The switch surround (53seconds) suggests that it is (was originally) a three-position switch, so you don't get away from useless features quite so easily.
How come your comment is listed as being posted 11 days ago on a video uploaded today? |I smell a conspiracy theory coming on.

Unfortunately, it is really hard to get good heat sinking for a powerful LED (array) with a plastic box like that.
Now you need to turbocharge this torch Clive :)
Have seen similar flashlights in senior care homes, they contains the 6v lead-acid battery and not so powerful beams. They are selled as emergency lights when main powers are off.
Lead-acid batteries are maybe better (or safer) in them, because they are usually sitting 24/7/365 in their chargers, waiting for emergency situation which hopefully is not coming. Li-ions/polys maybe aren't good on always in charging devices.
Pish and pished has become part of my vocabulary now.
Interesting light
I've had a couple lights of similar in design, but with 6v or 12v sealed battery inside.
Almost looks like they had a bunch of cases lying around and thought they might as well use them!
I have a similar halogen torch that looks the business, but is pretty dim!
This video title makes me happy. Not enough use of "pish" on RUclips despite its effectiveness as a descriptor
I had the old "1 million candlepower" version that came with a halogen bulb. I turned it on and it worked for literally 1/2 second. the battery came dead inside it. So I took it apart and converted it with one of those 100W LEDs and a lithium battery pack, and a way too complex control circuit that boosted the voltage up to around 40V that could PWM the light and monitor power draw on a small LCD.
The reflector was probably designed for a standard incandescent bulb and the LED replacement does not sit at the focal point.
I had a similar light back in 2008. Same casing. Except instead of an LED it was a high powered halogen.
Halogen is probably better for light output than one led😝
Even Xenon HID😎😎💪💪
You could fit so many lithium cells in that bad boy...... and a modern LED package up front (will probably need a heat sink stolen from a computer and a maybe a tiny fan... but you have all the case size in in the world)
Could be such a beast.
How about a 3d printed holder for multiple 18650's and a JLCPCB pcb for charging / protection as a future project ?
I haven't got time to watch this now, but "pish" is definitely used in Fife! At my school in one of the maths classes there was a design on the wall made by threading pieces of coloured string in a regular pattern between nails. In the gap in the middle some naughty pupil drew a smiley face, and then later some naughtier pupil wrote "This is PISH".
I bought 36 bottles of Bucky during the great drought of 2020 with a view to charging extortionate prices for them. Ended up giving most of them away fs.
A 4v lead-acid... Will wonders never cease? I bet it works better with a single lithium cell and one of those little 4056(?) charging circuits. (watching the rest...)
Also don't underestimate the power of patenting crappiness! That's how the automotive industry and many others makes their money. It's what many industries do when the limit of technology peaked decades ago.
Daiso has mini flashlight 🔦 that uses one AA battery, just $1.50 far better than this one you're presenting,
Not to get away from electronics. You should make a video on the eBay wine making and explain the FUNdamentals.
Could of fit one if them old school jumbo spot light square batteries in this light wow so much waisted space
I want to see StyroPyro mod one of these into instantly set everything on fire
Will we be seeing a modding vid of this, where some bearded fellow crams so many cells into it that it only needs charging once a year? LoL.
This is the budget version. :)
The full version has red glass and an emergency light on the side. It may flash red.
That's all case. Proper pish!
You could stick on one of those 3D printed sockets you made and whack a battery in out of a cordless drill. That would keep your little light going for a while. Or out with a bang if you hooked it straight to the existing circuit board...
Just going to quickly comment before watching. I love the title. More Scottish swears please. Reminds me why I love this country :D
**EDIT**
Ok, watched it now. Would you be able to show us a video of you modifying it?
It should be forbidden to but extremely bad and low quality products on the marked
We reserve the interjection "Pish!" for the moment just after a mediocre to poor drama series has ended, or even a good one which has got a rather pish ending.
Is this that famous shatty horror game narrow light? ....impressive
It looks like a great case to build your own light/powerbank combination, but as a complete product it seems like a crap product
There's plenty of room in there to add an ozone generator so you can sterilise the places you are searching. 😀
Clive, you can't just leave it there without you hacking it and improving it.
so lets wait for the pink led 18650 hack video then :)
It also needs a lens to spread the light beam.
Mod it Clive! we all want to see what your efficient mind comes up with :)
Clive, you could make a video about modifying this with a more powerful LED and the said 18650s and charger. Through the screen it seemed that the battery is only half the problem, the LED seems to be quite weak for such a large light.
I love how as it opened I thought "that looks like a lot of room for hacking" and you're like "fill it up with lithium" and your comments are full of ideas on how to hack it.
When will mass production of rubbish end 😭
I think this thing may have been sold as a "barely usable" state because the intent was for people to mod it and having it be a barely usable flashlight makes those who do mod it not feel bad for ripping out the underwhelming bits that come with it for what is a fairly decent case and reflector cone.
Seems like the light housing is way to big for what's inside it to run it
Upgrade it, stuff it full, lets see what it could be.
That's interesting: In German "pischern" is a colloquial and somewhat antiquated verb for urinating, I wonder if it stems from the same origin.
It also means to urinate. As in "Having a pish."
Can we get a review of the new LEP white laser flashlight?
I know its oot but everyday, i always play your video and take a nap at noon by hearing your voice.. the best voice ever 😁🙏 sounds warm to my ears..
A lot of people use my videos to help them sleep.
USB charging & a Lead Acid Battery just seem like a weird combination to me. Actually the idea of a high tech(albeit simple) product with just about the oldest battery technology is weird.
Just remember 12v pb acid batteries are STILL powering the electronics/computers of pretty much all motor vehicles on the road today, and they are 100% reliant on them to start.... Even ELECTRIC cars still have a 12v pb acid battery to run the computer and 'start up' the main battery. Tesla this year actually did away with the 12v pb acid battery on new models in favour of 12v li-ion, probably the first manufacturer since the war to do so - and not without complaint, critics argued that running the starter battery stone dead accidently (leaving lights on the most common reason, continuously cranking a car with no feul or the immobilizer triggered until it dies the next most common) is extremely common, and while it does little damage to a lead battery which you can easily bring back to life with a jump starter or a garage charger, 12v lithium is a different matter. I have even seen forums where people are describing how to replace the lithium battery in thier Tesla with pb, and how to phool the computer into thinking the lithium battery is still there.....
seems like a really nice light actually. IE very user serviceable and hackable.
Reflectors and big battery boxes on torches are really a throw back to incandescent bulbs, which needed a lot of power for little light, and whose filaments radiated in all directions. LEDs are pretty directional already, and if you take a 5mm LED as an example, can simply emit almost all the light in maybe 20 or 30 degree arc.
That was my thought too; big reflector pretty well superfluous. The LED and the small LA battery could go into a much smaller case and deliver the same performance.
Talk about "room for improvement" inside that absolutely cavernous container! WOW! You could absolutely load the insides up with battery of whatever flavor you want. Heck, just using as a container with the input/output terminals on a disk of plastic on the front where the LED used to be. Nice that they put the LED on a little connector like that, but solder the battery to the board/terminals. Maybe gut it of all photo-emitting powers, and then load it up with LFP batteries, and have it as a gigantic portable power bank, with built in extra FANCY carry handle. And moderately water-resistant if you would put a smear of silicone in the gap.
I know I have said this before, but people always ask me what possible use those tiny lead batteries would have: Emergency/fire lighting fixtures still use them, due to the stupid simple circuitry needed to keep them trickle charged all the time, and to detect when the power goes out. I would bet you cash money that these same PB/SLA batteries are in the tiny "Exit/Egress" signs, but the market is being slowly replaced with the LFP versions, and/or super cap, so they have to sell them somehow.
I modded something similar XD. I gutted it, Installed 3x 18650's & an HID headlight bulb! Its ridiculously bright XD. Even takes a minute to reach full bright ^^
I can't get over how empty it is. Presumably to trick you into thinking there's a hefty battery inside. I've had pocket torches that were brighter.
Time to mod this with a 3W LED and some lipo cells
It's funny that a tiny pocket thrower like an Noctigon KR1 will have better light, longer throw, better battery life and the convenience of replacable battery (1x18650) and stepless adjustable brightness in the size of just the handle of this light.
More battery (salvaged 18650's from laptop packs). proper BMS and higher power LED and you have something.
Chunky and simple stupid, but nice in that there is sooo much room for modding. Could make a retina scorcher or a run-forever light with this enclosure. (Doing your own build inside that might be fun for a future video.)
I was SCREAMING . . . . . The SCREWS in the Handle at com'uter. . . . !
Poundland does a D battery version. . . . . .
That looks more like it was designed to smuggle contraband with the superficial appearance of craptastically poor flashlight, than anything else, to me.
I had a thought we should help China make the right decision about supporting the Russian government by not buying farting dog toys until they make the right choice.
That torch body looks like it would be interesting to hack with some sort of inverter and a 35w CDM-R lamp!
The thumbnail reminded me of the show Still Game.
I get those exact LED's with and without the PCB....The 1W/3.2-3.4V/350Ma...3W/3.2-3.4V/700Ma...5W/6-7V/700Ma and also a Fenix flashlight replacement LED [PCB only] 10W/2.9-4.0V that puts out a little over 12W connected to a fully charged Lithium Ion battery. [4.2V]
You could easily put in a 3W, thermal glue a copper plate on the back with of course adding thermal paste under the LED PCB and a few 18650's in parallel for a quick easy upgrade. Or ad a larger copper plate and use a 10W LED chip for a "Tim the Toolman" upgrade.
I hope this light was absolutely dirt cheap. Some genuinely excellent 18650 flashlights can be had for not much money. A Convoy C8 is under $25 USD, and some of the base model convoy S2+ flashlights are around $15.
I measured back in the mid 80's using a calibrated Data Precision LED DVM the voltage for a brand new fully charged [Trickle for days and allowed to settle] 12V lead acid car batteries and the voltage was 12.865V
As a fellow Scot, I can attest to the fact that this light does indeed look pish. Shame on the AA for putting their name on it, you'd think they'd have a bit more pride in their name/brand.
Curiously (automotive/leisure) Lead-Acids were going for £480/tonne when i weighed a few in recently.... which meant it was worth the drive to get £20 back for four 'doorstops'.
The current measuring faux-pas with the UT210E (which i've done myself) can be avoided if you get a UT210D! - AC/DC are selected on the rotary switch. (Nought to 200A). Only downside is you lose the millamp resolution, getting 10mA instead.
“Design patent” means basically registered copyright on the look, not the technology. Equivalent to “registered design” in the U.K.
Most definitely designed to be a cheap POS, especially given they skimped out on even fitting a single 18650, cheapskates... :\
I had a torch like that years ago I bought from Argos. It was branded under the Challenge name. It was the same as that one except the battery was a 6v lead acid and it was the charger doing the 'intelligence'. The charger was labelled 'for sealed lead acid batteries only' and had a red and green LED on it for charging/charged and power. The battery failed in a short while. I think I still have the gubbins from inside but I threw the case away as it had that horrible rubber coating that went sticky. The other light I bought was much bigger with a halogen bulb in it, bigger charger, still branded Challenge and had a 12v sealed lead acid battery in it. I still have it but the battery is long dead. Another LED torch I bought from Argos has 8 LEDs behind lenses, 7 round the edge and 1 in the middle, again years old, battery dead though this time a flat NiCd or NiMh pack, I cant remember. It is supposed to be weather proof so I was going to replace the LEDs with slow fade RGB ones and make it into a solar garden light lol, still never got round to it. Thats typical me.
Does that huge reflector actually do anything? The LED only sends light in one direction.
😂😅🤣
@10:30 "It's a big huge box with a tiny battery in it!"
ROFLMAO!
LEAVE MY EX OUTTA THIS
hehehehe
😂😅🤣
Seriously... I almost peed.
This is the best described YT Video I have seen. I have been laughing for hours. "UTTER PISH!" says it all. Dont hold back Big Clive......just say what you mean. LOL
We were given similar torches at work a few years ago. That panel on the side had a strip of LEDs in there as a floodlight. Didn't last very long.
Hah, looks like everybody had this one. Ive got mine, in original box. It came from Harbor Freight.
Called the Night-Search Eye 2925....1,000,000 candle power Innovative High-Quality Rechargable Halogen Lantern with Super Bright LED Light Tube
Has the I II toggle. The side led was pretty pathetic
Its been sitting on my project shelf for over a year. I have the parts. The main beam will be one of those Ultra Fire drop in modules. Seriously good beam for ~ $10. They rate them @ 1000 lumens
Side LED to be replaced by 1 or 2 of the many cob panels i have laying about
And Two 26650 cell holder in parallel, to be able to use 1 or 2 cells
Thought It would make a nice camping light, once I get around to it
Would be a nice flashlight to mod with 18650's Is lots of space and upgrade the led
Looks like some chinese factory copied or bought the mouldings for the case and bodged in a small battery, cheap LED in it thinking they could sell it at a big profit whilst cheating the purchaser...as per usual. However, it does have hacking potential 😎👌
Its ironic that you would have had a much more rounded number had you not rounded 13.8V to 14V
🤔🤔🤔Hmmm.... Time for a 'tune up' methinks...
Higher rated SMD (with a bigger lens cap on top utilising the reflector more to make the beam wider), replace charging circuit so that a higher capacity LIfpo/NiMetal/newer battery tech and increase water resistancy'... Might make for a decent torch then... 🤔😏😎🇬🇧
Chuckle. You could put a boatload of 18650's in there, a buck converter for managing voltage, and a BMS circuit ... and with that mounting setup a better LED ... all without bodging the case much. FTM you could put a much higher wattage LED in and a cooling fan if you wanted.. What's the point of such a waste of space? I have many torches much smaller that put out much more light (and probably just as cheap).
Reminds me of my EverReady Halogen filament ‘Dolphin’…..big, plastic, with the light output of a sick glow worm. Since I ditched it I’m a total LED Lenser fanboy in all forms….
On the topic of portable lights. Recently daughter ended my "not-sh*t-still-cheap" torchlight. Decided to at last buy decent one. All that have standart batteries was low output, or got piss-poor working time. So opted for one with 18500 and charging, the led was something XP-G3 I think. Man, for its size it got some light. Like a day and night what I was using before. Now going near torchlight stand at average store, they all look like childs toys compared.
Clive this is the base model. The other models have a plethora of battery and LED choices for the retailer to choose from.
Thx for sharing the teardown. It doesn't get any more basic than that. I wonder if the PCB pick and place machine was organic. I'm surprised they even used a PCB. Could've been everything flying in space. Maybe heat shrink tubing cost more than a PCB. Who knows when you're making a bazillion units.
Again, thx for sharing.
Here in the states, we have a discount store called "Ollies". It was about 15 years ago I was in there and they had these Steelton Tools branded, "1 million" candlepower searchlights for like 30 dollars. If that light was 10 million CP, then my butt is too! If I'm being generous, I'd give it about 750 thousand CP. . It was a slight bit dimmer than my Brinkmann Q-beam 1-M. (A Legitimate 1 Million CP spotlight) Physically the thing was huge. The lens and reflector was about 10 inches to a foot across. It was heavy too as the body of it was indeed stuffed with as big of a 12V SLA battery that could fit in it. It had two switches up on the grip one for On/Off, the other for "High/Low" The battery was decent, but the 55 watt H3 automotive foglamp bulb burned through it within 20 minutes or so. I took it to work one day and someone borrowed it. I got it back with the glass lens smashed out of it. I had to go to a local glass cutter and have him cut a new bit of glass for it. 10 dollars there..
I eventually made some improvements to it. I happened to have some of those little blue LED stick-on mini spot lights, that could be used for accent lighting in a car/truck (Like lighting up a console or place on the dash etc) They ran on 12V obviously. I took two of them and wired them in to this searchlight, on their own little switch. Those were stuck on either side of the reflector, just behind the glass, and pointed straight ahead. I also added a 12 power socket mounted to a bracket on the side. Now, it was not only JUST a searchlight, but a relatively useful powerbank. It could charge a phone easily. My girlfriend (at the time) and I liked to go on walks after dark, down the bike trail near our home. But she would get spooked by the deer and raccoons rustling in the bushes. So the light came in handy for that as well. Just walking along I had the two blue leds lit to provide just enough light to see about 20 feet ahead of us, But if needed, I could flip the switch for the main lamp and light up everything for about a 1/4 mile ahead. But just using the 2 leds, it would go for a few days or more. (I tested that)
But one day I dropped the damn thing.. The brittle plastic case shattered like glass, the glass lens shattered, again.. and the SLA battery burst, leaking its fluids all over the floor. I salvaged what could be salvaged and tossed the rest. Those bits are still sitting around here, in a box, somewhere amongst the cobwebs.
The one I had was similar to this one on Amazon... (link)
www.amazon.com/dp/B001B7ILFC?ie=UTF8&*entries*=0&viewID=&*Version*=1
I've got a very similar unit, but made with an extruded aluminum body. The problem is that leaving the charger on cooks the SLA battery eventually. In my case, it took about 6 months. So much for standby use. The awful part is that a replacement SLA battery costs more than the unit cost originally. I stuck 3x NiMH cells as a replacement, but that's a bodge. FWIW, the innards were stuffed with plastic packing bubble filler because of the smaller battery size.
The led modules could you buy by 10pcs for arround €2,50 from aliexpress. And that's the 3w version. Maybe this is the 1W version?
Now if you could bung in something like a 10W LED cluster, that's small enough to work with that reflector, then you'd have something to work with. Battery power's not the issue here. It's lack of LED grunt.
I'm a simple man, I see that word in the title, I click...
On SLA batteries, I always think they're great for people who only ever want to use the first 20% of the battery.
It would be funny if you found a standard 5mm white led in there as the 'bulb'. I had a torch which had 9 of them in parallel across 3 AAA cells. It drew about 0.4A which was way more than the 9x20mA maximum rating for the LEDs. The LEDs died one by one and the torch got bluer and bluer as the current to the remaining LEDs got larger and larger. I didn't get, for a few pennies, why they couldn't add a resistor to limit the current. I was equally surprised to find no resistor charging that battery as all SLA batteries have a maximum permissible current and I can't see that battery being big enough to handle 1A or even 2A from a usb charger. It looks like maximum 1Ah which would have only been 1 or 2 hours light.
Waiting for part 2, "Big light, with big battery" ask Styropyro if he has any ideas for LED replacement :D
the connector is handy. I see an upgrade to 16850s an new innards 2x👍 just a thought this is NOT a bad dragon design. It iss a bit brick like 🤣🤣🤣
