Hello again Clive, I just love these "Oh let's pull it to bit's anyway and see how it tick's" video's that you do so well. You must have the best job ever pulling these little things to bits. Your channel is one of if not the best of all the "Bust It cause I can" video channels on KZread and I spend a lot of time watching Big Clive pulling things to bits to see how it is made. Keep up the great work Clive. Cheer's From Down - Under Australia (Perth).

Hi Clive. I know a few people (myself included) who own these lights. We use them for night fishing. The red led is designed to give someone who is walking behind a point of reference to the person in front when the headtorches are being used for hiking and treking. They are very bright and work great as fishing head torches. Thanks for the strip down 😁

i love your el-cheapo product reviews and teardowns. you're the best bigclive. keep up the good work.

Thanks, very interesting. I and my fellow group of fell runners (Mountains, for our US friends), use very similar head torches to these, and they are really very good,our kit tends to get abused with rain, sub zero temp, falls,etc, and they survive very well. £10 delivered from China, whats not to like, well.... Main problem you do tend to blind your running mates if you look at them, but the real bad point is the intensity of light stays constant, and then wham, it cuts out, and you are on top of a mountain,freezing cold, dark(Obviously), and in deep doo doo. OK it does have a warning light, mounted on the back of your head to warn of low voltage, but you cannot see it when it is on your head. Thanks again for your informative video,we all carry a second torch just in case.

I have been using a Cree led mounted on my work helmet for the past year and a half. It's been superb. Very useful on night shifts in dark dingy places. My only gripe with them is how far they project from the helmet. And the cables needing a re solder once or twice as the wire fatigues.

I found a similar IC in my flashlight and the two spare pins actually set the modes on mine. By shorting one to ground it disabled the flashy mode and is just Hi-Low-Off now. The long press SOS still works. I like this IC because the switch doesn't carry any current - with my previous flashlights the switch always became intermittent.

When I was working on trains we used to fix this type of lamp to our (mandatory) bump caps. That way you didn't end up with a dent in your forehead by the end of the shift. A lot of our work was done over night and the power would be on and off either because the train software wasn't quite there yet or because the train had gone into 'loadshed'.

This video came in handy, as I just purchased one of these, for $10 US, and I am intending on killing the red LED in the battery pack, and killing the strobe light, by adding an extra power switch to the power lead, so one doesn't have to cycle through all the differing light states. There is no way to kill the strobe through the chip. Thanks for the video!

Awesome my good friend.

these things are great, ive had loads of head torches, all a bit crap, but these are ridiculously bright, even on the low setting. great for cycling , walking and working. the elastic tends to be a bit crap and stretches after a few weeks and eventually becomes useless , the buttons can get hard to press, other than that, with some decent cells such as Panasonic, Torchy etc they are amazing for the price. I keep buying them for friends etc now. You won't even bother with a big torch anymore . Thanks for the look inside. be fun to hack one , lose the strobe nonsense and fit a dimmer switch.

I love how it says "LED HEADLIGHT" on the sides just so you'll never forget what this contraption is.

The red LED at the back is a safety feature to stop trucks hitting you from behind. This especially useful in submarines, sewers and while ice climbing.

I've always understood that it's best not to use protected cells in a flashlight, because they shut off at a certain voltage to "save themselves. That's great until you find yourself in a position where a damaged cell (but working light) is better than falling off a cliff. If you see what I mean. Thoughts?

If you're in a situation like that you should have a backup torch, and a friend who can give you his backup torch if you break both of yours. If I'm doing a night dive on SCUBA I carry my main torch, two backup torches and a strobe. The illumination under 20m of ocean at night nil. You wouldn't be able to see your hand in front of your face; but part of SCUBA training is being able to operate all your gear with zero visibility. The most serious problem is signaling. If you surfaced out of position and didn't have a torch to signal the boat with you would be monumentally fucked.

I bought the same from Amazon. It came with batts, wall and USB chargers. Worked well for a while then the batts got very weak. Bought some good Panasomic batts and it works well. I found out about the SOS mode by plugging the USB cable into a PC. It jumps into SOS mode for some reason. I do wish it could focus to a wider beam sometimes.

great video Clive. I have a couple of the cheap 7 LED "Cree" lights for the front of my bike (offroad use). for around 20 quid they are amazing value. the multi led ones have a small boost converter inside the light unit itself (and no reverse polarity protection). different brands all seem to be based round the same template design. Same modes available (full, half and strobe - not sure about SOS, will have to check) and mine both have an obvious flicker on half mode. clamps and battery packs they provide are terrible.

When I was in the US Army Basic Combat Training course back in 1970, we were issued two small strips of luminous tape, it was to be applied to the back of our helmets for night operations. When we were walking through the deep forest of the great Northwest on Fort Lewis Washington, you could see where the fellow in front of you was by this tape. You were supposed to strive to walk just the right distance where the two strips seemed to just separate, and thus be safe from bumping into each other in the ever so dark night. It seemed to work, however I never again saw that tape being used anywhere for anything in the following 8 years of active duty.

The red LED on the back is to let people behind you know you are there and stop them walking into the back of you. I used mine for exploring mines and caves, very reliable and almost always on the reduced setting. It's a really nice light.

Ive bought several of these over the last couple of years. they perform well. If you replace the lens with a flat piece of plastic they give a much wider beam, much better for a work light. They seem to be designed for cycling. Biggest annoyance is the headband is small so wearing it with a hat is not possible unless you have a child sized head.. Also the annoying strobe mode is useless. Would be nice to find a way to disable that mode completely. If you order with batteries they are always counterfeit and far below the claimed mAH rating. Thanks for the great review!

I think the original use for the headlamp was for biking and they just kept it in all the models so they can rebox it for other uses. The red LED in back is so when you're biking at night on the road people can see you from behind.

Oh my... the end surprised me.

Hey Clive you should take a look at a Fenix or Thrunite headtorch. If you are impressed by the brightness of this, then a real one will blow your socks off!

Hi there Clive. I do have many Chinese flash lights,some head torches too.From very cheap £1 to £60 MagLites and Led Lenser ones.The CREE leds are fairly cheap these days and in your lamp you have CREE T6 i believe it is 4000k,as it looked light blueish. Some light modders run these leds at 4A+ but you need a lot of heat sinking for that.With a proper 18650 Bat you can get it above 2A on high. Trow that UselessFire in a recycle bin and get yourself an used laptop battery you will find better 18650s in it.There are a lot of crappy and dangerous 18650s on ebay, and some decent ones in between. There will be a big difference with a decent battery and longer life. Have fun and be safe. You know what you are doing anyway.

I have a few of these. They are really useful for allsorts. In the loft, under the floor, working outside. Emergency backup for walking in winter. Just need to get good rechargeable batts. Many from ebay are fake and nowhere near capacity they claim. Oh bloody hell I already commented a while ago and can't even remember!

You can take the light off the band also. On the rear there is a small indent for your thumbnail or similar. Lift the lever slightly and the light slides off the plastic carrier.

Seems like it's pretty legit for a low-buck version. Features and build quality from the disassembly don't seem bad at all.

(Not that you'd do that all the time, but in an some emergency it matters.)

thanks Clive. RLTW!!

I have one like this from Amazon. Great torch but the charger was a deathtrap and I had to mod it to incorporate a fuse and greater clearances. I didn't test the charger enclosure for flammability (obviously) but I never leave it charging unattended

I assume the Red LED on the back, is so colleagues can easily find you from behind and gives them an indication as to where you are, for proximity. If you can see where their light is shining, you still do not know exactly where they (the source) is. So you don't actually knock them off the cliff ETC. If you can find someone's head in the dark, chances are they will be just below it. Also good when riding a bike, to be seen from the rear.!

Could you do a video on some of the other "Cree" LED lights from China? There are a lot for $0.99 shipped on eBay, advertised at 2000 lumens and the like, in aluminum colors. I'd love to see a breakdown of one of those.

Doubtfire! I like it!

Would love to see a tour of your pinball machines :D

I have the Atomic Beam brand of this. The switch is on the side of the headband though and it only uses 1 18650 or has the adapter for 3 AAA cells.

The little tab on the led retaining ring is probably a 'dog tooth' that gives the steps when you rotate the focussing ring.

In the states, those were sold as bicyclist headlights. That was the excuse for the red LED.

Doh, having read through the comments the cyclist aspect has been mentioned LOL, On a completely different topic. I'm a spark by trade and many people ask me about upgrading from Halogen down lighters or incandescent down lighters to LED and even upgrades from and too the relatively short lived compact fluorescent technology. Having thought about it I realised just how complexed the subject becomes so I think the man for the job is you.I know GU 10s are easy to change like for like but electronic ballast driven 12v halogen can get tricky if the ballasts have a minimum load expectation. The old Eyeball spots 240v BC or ES can present issues in locating the right lamps. I thought I know rather Large clive understands the UK maket for lighting solutions and would more than likely have some fittings to demonstrate how it all works. Thanks Clive regards Sean

+Sean Regan I recommend against using the original electronic halogen transformers. They put out a high frequency spiky wave that peaks at about 30V. Better swapping them out for generously rated regulated 12V DC supplies for the longest reliability or swapping completely for GU10 lamps.

@seanregan730

8 жыл бұрын

+bigclivedotcom Totally agree. The reason I thought it worthy of a video is that on inspection some 12v Halogen transformers will work okay with LEDs especially the old transformers where as the electronic ones don't like the low load of LEDS. sometimes you find that a whole room or area has any number of transformers serving 1 or more lights each. finding and replacing them can be a pain and if they are screwed down out of reach even more so. with LED 1 driver can be used to power larger numbers of fittings. sometimes its better to rewire them all and connect them to 1 LED Driver. However I rather hoped you might do a video showing the various different ways of upgrading to LED showing some common scenarios from existing halogen installations. Its an often asked question thrown at me and of course each installation is different. I hope youll agree and maybe cover the subject in future videos cheers Clive

Red LED on the back ... Quite useful, actually; Assuming it's really, really, really, dim, and switchable on/off.

white/blue LEDs apparently self current limiting and tuned for 3.7V batteries. so they have no extra resistors or anything.

I have a pocket torch / flashlight, that says "Cree" It uses one 18650 also. On high it it gets uncomfortably hot after just a few minutes. It claims to have an output of 1700 lumens running a Cree, T6 7 watt LED.. I can tell you, it will over power my 55 watt headlights in my car. Mine is the old style, if you use it on low, it will be on low when you turn it off and back on again. I found one very interesting. Even on low power, it is so bright, using it to see the inside of a PC is hard to do, one reflection blinds you! Almost to bright for daily use. Better for tactical.

Thank you for taking it apart now I do not have to

the xml-t6 should be driven at 3 amps. Also word of caution, the batteries in one of these install in parallel, if someone doesn't pay attention and installs the batteries in the conventional series way you are creating a dead short.

I think the red led is for riding a bike.

Other people drop the bass or a cup of coffee. Big C drops the voltage and the iPad! :D

Hey mate i have taken apart a similiar light and even thought the board says CREE on the MCPB its most likely a latticebright all these lights seem to be the same internal just look different on the outside mine is the same as yours! The specs sheet is right i measured my current at the LED it can do about 2.4amps!

we have three that have held up for three years they do get warm after a wile

Same one I picked up for a friend!, Wasn't sure how decent the charger was though

Hi Clive, Not read through comments but the Red LED might make the unit appealing to cyclists white front red rear. thought it worth mentioning. cheers for the vids.Sean

Ha many of these Chinese lights boast an output of 2000+ lumens. I have an old Maglite with a genuine cree led upgrade fitted. It's rated at around 180 lumen. I tried out a 2000 lumen light off ebay as a comparison and it was only slightly brighter. I also have a torch from also that is rated at 500 lumen. That light is far brighter than the ebay 2000 lumen torch. I think the Chinese add an extra 0 when giving a lumen rating. Great video. ATB Steve.

This flashlight is good. (compared to other Chinese headlights) Only really bad downside is the zooming mechanics. The o-ring will break quite fast and it's there to provide friction when zooming and to hold it's position.

Clive, about shipping the batteries from China, there was a recent ICAO rule change that effectively banned lithium batteries as cargo on passenger airplanes. I'd expect that to be a factor in the clampdown you've noticed.

Suddenly becomes a found footage video at the end.

the Red LED on the back is for safety purpose like if you used it while riding a bike on the road for instance. the Ultra Fire batteries are the most ripped off batteries, if you can be sure they are original one's then the rating should be fairly accurate, some however are reclaimed laptop batteries re-covered in new plastic cases (I heard) so beware...

You sir are a brave man, putting an ultrafire cell that close to your body, those things are leathal when used in high amp situations, actually you should do a teardown and see what is in it, i would imagine a lot of sand for a start :)

The LED is likely a Lattice Bright CREE knockoff. Very commonly used in low budget "CREE" lights. I could tell already by the really cold color temp when it was turned on by itself. Lattice Bright used to even copy the CREE model names as well but recently changed them.

That tumble gave me quite the frighten.

It seems most of these style LED flashlights have the annoying strobe effects. I have a decent hand held one I bought off fleamazon and I it's a "touch" button so very easy to switch to strobe when turning on/off. I'd have to look into what it would take to take it apart without breaking it so I can just change the circuitry. I like the idea of using the standard lithium ion cells though as you can always have a separate charger and spare cells and have lots of light for a long time if camping or something then charge the cells back up with a solar charger during the day.

HOLY FUCK I jumped a little at 17:38 when he dropped the camera xD

the red LED isnt pointless if youre a cyclist, that head torch would be pretty damn good for cycling because its so bright and you have the red light for the back of your head, an all in one package

I have had a similar headlamp, without the zoom, for the last year. The only faults have been related to the plastic parts. One of the plastic fingers that hold the lamp assembly to the strap broke off. The outside of the battery case has developed a couple of cracks, unable to cope with flexing. Nothing some pound shop glue cannot fix.

I put foam tape on the back and front part of mine because they're uncomfortable to wear for an extended amount of time. For the price, I can't complain. They're bright and my Samsung 18650 cells last several hours if they're charged with a decent 18650 charger. Also, I'm assuming the red light on the back is added as a safety feature, say if you were riding a bike or something.

Back LED is a "head count" light, so if you go face down in the mud you're still blinking.

That "annoying stobe mode" is actually a distess signal.

The red LED is meant to be seen not used to see by. So we don't want it bright and blinding people behind. In my opinion they are correct to have it the way they do.

+bigclivedotcom Yes, it is cree. Yes, they are cheap enough to go in cheap lights. No, it is not 2000 lumens - at 1.5A, it should be pumping around 500-600 lumens at the emitter.

not bad quality for 5 pounds it looks well made :-)

The led on the back and the flashing are for cyclists. I use this exact one in my shop, and it holds up shockingly well in that harsh environment as chap as it was!

I've just discovered your channel and haven't seen all your videos but I have to ask if you have an oscilloscope. It would be cool to see the change in duty cycle or frequency at different power settings and just what frequencies they use.

I've had a few head lamps over the years and find the part that seems to fail most is the elastic head band which is really annoying seeing as though the main bits are usually well made and would last a very long time. Also have a few "UltraFire" 18650 5,000mAh batteries and the name really put me off especially after the incidents of fire caused by lithium batteries over the years.

It can be used for climbing fishing repairing construction and power cuts cyclists and night walking

I made a few boxmod's with 18650's and oh boy those things are dangerous, you don't want it against your head............

Clive you should check out a good headlamp like a Zebralight H600W. I would love to see a teardown and reverse engineering on that.

So glad you like it, because I've owned one for a while now and I was worried you'd hate it! Heh heh!
