20W 9xAA Cree LED torch from Lidl - test and teardown
HTML-код
- Опубликовано: 30 дек 2018
- Today I tested a powerful 20W zoomable Cree LED flashlight from Lidl supermarket. It has 4 modes and it runs on nine AA alkaline batteries. It has just a single big LED instead of multiple small LEDs. This allows for the zoom function. Let's see what's inside :).

Thank you for your once again very detailed video. I also bought 2 of these flashlights before Christmas. For 15 euros per flashlight, this is a good flashlight and also good for modding. The Led is a Cree XHP 50.2 Led (18W), this is available as 6V / 3A and 12V / 1,5A type, max 2654 lm, max. 165 lm / W. I drilled 2 opposite holes into the aluminum head, in order to be able to open and screw the head better (for the Led driver).I removed the small plastic disk and cleaned the head of thermal grease and glued the Led board back with thermal glue for better heat transfer. As an alternative to NiMh AA batteries 3x Li-Ion 26500 cells would be conceivable (3x max 4.2V = 12.6V). It would be great if when once could reprogram the microprocessor to remove SOS and beacon and add a third very low brightness (moonlight mode).
Thanks for your many interesting videos. You have a nice cat. Greetings from Germany. Wish you a healthy new year.
A few people posted schematic in the comments. So fundamentally you could replace the mode control IC with your own microcontroller. Chances are whatever's on there is either OTP, or a custom or semi-custom IC that replaces a microcontroller used at prototyping/development stages and thus sharing the footprint with a microcontroller.
Happy new year.
Happy new year to you to!!

EDIT sorry wrong thread
Over time, I got used to your accent. But please be aware of the different pronunciation of flash and flesh. This could avoid potentially very awkward questions about your Christmas present.
First time viewer here and this is exactly what I first noticed....
I was very.... very afraid this is not a FLASH light review....
Czech accent
Why an Earth all of these LED flaslights have tose blinking etc functions? I want flashlight with just ON/OFF switch and nothing else. Or at least a system where you can change the function separately and the switch is just ON/OFF switch.
I have a bunch of these - the special modes are accessible on half press of the button, so you can turn it ON/OFF without cycling between the modes that nobody wants. www.aliexpress.com/item/LED-flashlight-Tactical-6000-Lumens-CREE-XM-L2-Zoomable-5-Modes-Black-aluminum-alloy-LED-Flashlights/32696375029.html
I modded one of my flashlight just to remove those blinking and halfbright modes, it is much better with just a single mode. Having a potentiometer to regulate brightness separately would be even better.
SOS
If you're stranded and you need help, a repetitive flickering light will get more attention than just a bright light. Rarely does natural stuff pulses repetitively.
Also why we think aliens will send pulsating radio waves to us.
well these functions are used,then you do crash landing/ship sinks..then you can use it as sos signal..i seen flash light what max distance is nearly 2km..
i seen theys kind inside emergency kit offen
Happy new Year from Poland!
It's a 6V Cree XHP50.2. This LED is not even breaking a sweat. You can run it at 2 amps and beyond for 2500 lm.
This year 2019 found your channel and i will stay subscribed forever. Thank you sir for so much interested information.
When people are celebrating new year, DGW works hard to keep us educated. Delightful. Happy new year.
You are so lucky to have such a lovely assistant.
Slavic accent, cats and electronics. Always makes the perfect mix. :)
Nice now I have to tear down my flashlights just to see if the are using a buck regulator. Great video.
Hey i wanted to buy it 1 week ago in LIDL but i refused, glad to see it here :)
It's nice to see you perform basic math on Ohm's law and explain fundamentals of consumer electronics 😊 I wish I were competent as you are.
The worked analysis is fascinating. Thanks for another brilliant video.
I love your videos, Diode, you're the best teacher I've ever seen!
Happy New year, and thankyou for everything that I have learned from you.
Veľmi pekné video, náučné a ľahko pochopiteľne :D
Posuvaš sa stále ďalej a stále sa to iba zlepšuje.
Working hard )))
Happy new year.
"...can withstand extreme shocks"
DiodeGoneWilde: Interestiiiing!!!!
Great video as always! Happy New Year DiodeGoneWild! Love your channel ❤
Well explained, i like your style bro,keep it up!
I can't wait for that SMPS teardown!!!!
Very good presentation, the voltage/current/power/energy concepts explained so that even a 14 years old would understand them. The flashlight might be a good deal to reuse the 20W cree led, I think if bought separatelly it would cost about the same and here you also get the buck converter, lenses, batteries, etc.
Amazing video at the end of the year/begin new year!
You always make very informative videos and I find them very helpful!
Keep up all the good videos and explanations!
You're awesome!
Hopefully you reach 100k quickly! Because you really deserve the subscribers. If i would see one of your videos for the first time, without seeing the subcount, i would probably guess that you have like 600k subs.
Have a nice 2019!
Seriously cool calculater, haven't seen one of those since the 80's.
Šťastný nový rok!
Perfektní jako vždy - rozborka a analýza i s "chlupama".
Díval jsem se i na tvé starší videa a tam se pokoušíš mluvit s více anglickou výslovností, ale teprve až když mluvíš "jak ti zobák narost" je to to pravé a má to šťávu!
Hodně elánu do další práce! Těším se.
Have a happy new year!
Is the nine AA battery holder the same size as three D type cells? If so would it last longer on the D cells, and if so how much longer?
Happy new year!!! 😊
Happy new year diodegonewild 🙂
Love your videos and cat.
Thanks :)
Happy new year and please lets see how that multimeter can read watts.
Výborné ako vždy, teším sa na ďalšie videá. Inak rovnaký osciloskop som vymenil za kartón tvrdých Spárt :D
Všetko dobré v novom roku.
Happy new year!
Šťastný nový rok a pokračuj v tvorbe!
Díky, tobě taky :) budu
Happy new jaar from Belgium , thanks for this great video . 🌟👍🌟
New jaar lol hahaha
I have seen many video you can convert your multimeter into watt meter. How
Happy New Year!
hi i bought in lidl I noticed that after 5 minutes of use batteries getting hot why?
That could be fun project. Turn that flashlight into LiPo powered one. Using LiPo cells with BMS board with charging capability. Also happy new year. Z pozdravom zo Slovenska.
Happy new year!!!
I have a similar product from Aldi-UK which uses 4 X C cells. I wonder why this one uses AA?
Well done man love your videos!
Almost 100k!!!! Happy New year everyone!
Hi, enjoyed the video. I dropped my Cree LED Torch and now it's not working! Is it possible to change the bulb as otherwise it seems fine! Also how to extract the bulb?
Hiya!
Haven't found this lamp at Lidl yet here in Sweden.
But, at Dollarstore more or less the same as above in your video is sold as an 5W with 6xAA.
Happy new year 😊
Do you still have your Christmas present? What does the clamp ammeter do when it sees AC? according to the data sheet the QX9920 should charge the inductor up to about 1.7 Amps and turn off (0.143 ohms 0.25 Volts). The input current should be 1.7 Amp pulses of shorter duration with higher input voltage (constant off time) (at 19:49). Ideally power in should equal power out (I assume the brightness does not change with input voltage). I'd also suspect the measurement at 4:45.
Please do this power supply review :D I cannot wait for it :D
Happy New Year
I am still wondering why lidl does not sell li ion batteries with a tp4056 charger or something else
What if you use 3 18650 battery in series it will work?
lov what you do, Happy New Year......always found it confusing on LED power ratings stated on the packaging, is it equivalent to an XX watt light bulb or does it use XX Watts? ( latter being useless for spec'ing actual illumination ). luminous flux is better, but, ya never know if an integrating sphere was used...or a light meter ...or just quoting the LED mfg's datasheet! Cheers
happy new year!
Best review video ever... regards from Split, Croatia
Happy new year 2019 !!!
Ha ha.. I like your style sir! (Your accent and verbal inflections adds even more entertainment value)
Where did you bought the calculator fron
Super video :) !!!
You re the best :))
I wonder if this can also work with 26650 lithium batteries
For disassembling flashlights you can try to pull on this zoomable part and rotate it. As this zoomable part grips this led module you might be able to unscrew this without damaging surface.
Quite nice review. I just wish, you would do an efficiency measurement. But I suppose it would be quite low, especially if current sense resistors alone waste almost 8% of power to the LED.
Ahoj, nemyslíš si, že proud skrz ty paralelní rezistory je 1,5A, naměřený na začátku, nikoli 3,5A jak říkáš 16:24 ?
Voltage drops while connected so voltage should be measured at that time also. (While calculating power)
Šťastný nový rok :D
Happy new year
hey diode, can you check if 18650 will fit & work in this body? It has this AAA adapter so I assume it could work with 18650 right away as in other chinese smaller ones for 3AAAs but just to be sure - this seems like quite good hardware actually.
No, it's too short for three 18650s.
DiodeGoneWild What about finding some decent Li-ion AA batteries and either modifying the battery holder for a 3S3P configuration. Or maybe just use 3 batteries and short out the rest?
a real pity that. Well thanks for checking anyways.
Can I please have a link to this product thanks and happy new year! 🎆🎇
It's probably not going to help you much, but it should be this one: www.lidl.de/de/livarno-lux-led-stabtaschenlampe/p290542
always good videos
As you can see this product is so dangerous I shouldn't even use it 😂
Made my day even 1 year later !
Happy new year 🎉🎆2019🎆🎉
Happy new year!!!
Isn't that 'mystery chip' just an atmel microcontroller, because of the 6 AVRISP pins probably for programming the chip in the middle of the board.
Nothing gets past the cat... 8-) Interesting video....surprised at the burn marks.
Very good, as always,
I love your videos!
I wonder if it would make a nice host for an LED swap and it looks easy to make it into a mule!
I verry like your vidéos, i French but the explication / language are good not so complicated
Seems like a decent device, the machined case and all. Is the main lens made out of glass?
I doubt, it would be dangerous if shattered
I'm guessing it would also fit 3 X 18650 in it or possibly an even wider battery. More realistic capacity of these is about 10.5 wh which would be closer but still not what expected. At very max might find a 12wh 18650.
I thought of using 3x 18650 or 26650, but they are loo long.
What about measuring the lumen output!?
HAPPY new year
happy New Year
Nice video
Please do more LIDL stuff. They have many interesting things (which i also buy) and I'm really interested in their quality
Igen.... :"D
Depending on the voltage, you could probably fit three LiFePo cells in that thing...
Není to v originále na 3x18650 Li-Ion?
To bude spíš na 26650
I got a flashlight sorta like this but completely different, it takes one aa and has zoom and high brightness, low brightness and flashing
Recently found you. Great Videos. You remind me of ElectroBoom or AvE
You should check out bigclive.com
Your cat is cute
Agreed
There are no non-cute cats!
I do not know if could be helpful but that is a Cree LED, the 5mm one is the XHP50 .
You can check it in their website, led components/products/XlampLeds/Arrays, look like thier XHP50.2 (more powerful, you can recognize from yellow bulb and the 4 chips), also you can check data sheet, that is pretty cool.
I am waiting a torch with their last model of led XHP70.2 way more powerful, that works with 18650 battery!
I have already treadown some flashlight with cree led and all work the same!
Incredible few days ago I fixed up a power supply 24V but 4.5A model LP2022-24 and now you will looking the 10amps version.
We have the same passion lol.
I will wait with impatience the upload of the video about power supply!!! They are my favorite on this channel please keep doing!
Have a good day, bye!!!
Thanks for identifying the LED :). They could have used 18650's in this flashlight, but with the batteries and a suitable charger included, it would be too expensive for a supermarket...
I like your cat with the flat face !
Not everyone can say that he has a cat that is technically supplied.
And a happy new year.
Zkus koupit 3x 26650 články, nebo změř vnitřní průměr baterky. Zajímalo by mě jestli se to tam vejde.
Bohužel ne, 3x 18650 jsou příliš dlouhé, 3x 26500 jsou lepší
Your accent is very unique! Im serious... 👌👌👌
I do love that really powerful flashlights are now affordable for normal people. I'd be all over the 'affordable' lights if they only got rid of the strobe, SOS, and let you set the power level for one click on (maybe a switch to tell it to go low or high once I press the cap's power switch). EDIT: Would you be able to fit (3) 26xxx sized lithium batteries in it?
I do love it to :) And I also hate the strobe and SOS. It's possible to bypass the mode chip, but you also lose the low power setting which I don't want to lose. Three 18650s or 26650s are unfortunately too long.
I hope Finland's Lidl will have this flashlight for sale some day... I would try to run it with 3 x 26500 Li-ion batteries
Happy new year :')
I hope for next video is about power supply computer, PSU 80+ vs normal PSU
Thanks
>>> Typ na experiment: Co zkusit vzít dva +- stejné MOTy, jejich primáry přendat na jedno jádro a tím si vytvořit oddělovací transformátor?
Happy new year! Well the Power should be calculated with the voltage under load. 1.5A/9 batteries = 170mA of current from each battery, which should drop the voltage some
This works if the batteries are in parallel; the batteries are in series in the flashlight; so 1,5A from each battery at around 13,5-14,85 volts total; so the power is ~20,25-22,28W
