AMount of Lumens it Produces and the mA it consumes during ON is NOT mentionedā¦ Also, I would like to know the Voltage Drop on these Type of LEDs and the type of LED it isā¦
You have asked a couple of similar questions in different threads. If we know exactly what you want members here may be able to help you more. You link to a light and ask the same question which unless someone has tested the light no one knows the answers to your questions. If you use the search function and dont find an answer I'd say your chances of getting an answer would be slim.
so, here does it mean that none has used it and I getting a positve feedback for it is narrowā¦
It seems so. But if you may decide to buy one, we would certainly be curious about your findings about the light :-)
Itās only available (as far as I can tell) at Aliās, for too much money and (you guessed it) strawhat LEDs and a plastic lensā¦
I already have oneā¦ I bought 2 of thoseā¦But, I want to know all the specs of it so the next time I buy a new one I know what I want exactly.
Thatās why I want to know the type of LED they are using and the Voltage DRop in each LED. THere are 12 LEds in it. and they claim they have 800mAH battery in it. so I wanted to know does it really produce 1 Watts output (as per their claim)ā¦
If, anyone can tell me how to measure it and calcualte all the findings thats more helpfulā¦ ALso, want to know the VOltage produced by that 800mAH battery and lumensā¦
HEre is a photo of the outside Box I gotā¦see, if u can help me more with itā¦
If the (limited) specifications are correct, and the 'light output' of 1W really means the power input of the leds (that is often the case) you can typically expect about 80 lumen from this light (give and take 25 lumen). If you want to know the exact output, you must have the light measured by an expert.
The given charge numbers (0.5W, 0.08A) suggest a battery voltage between 5 and 6 V, so I would not be surprised if a common phone battery is used for this light.
Can you make a (sharp!) close-up picture of the front of the light, showing the actual leds? I would expect generic chinese 5mm leds, but who knows?
I could not Understand your Part for āā(that is often the case) you can typically expect about 80 lumen from this light (give and take 25 lumen)āāā¦ why do you say that from 80 to 50 Lumesā¦
Such big differenceā¦ Let me give you a close look up for the LEDS in itā¦
Here are some more Photos to Tell me more details about the LEDS and the Lumens please if Possible.
thanks for the photo's. There is not much more to tell, i'm afaid. They look indeed like (generic chinese) 5mm leds, expect maximum output of 10 lumen/led that is maximum 120 lumens. It should run for a few hours on a battery load.
I hope that is all you want to know, without having the light in my hands to do measurements that is all I can tell.
It says that it has a 800 maH battery in itā¦ If I install a higher mAH battery in it; can it give a higher Lumens Power Lightā¦ Or the LEDās may fuse out of the higher Current. Any details guysā¦
Hi Farhaj,
I have repaired one of these. I will explain some details below:
Emitter:
This uses cheap 5mm emitters. By eyeball, I estimate brightness is around 20 - 30 lumens. IMO you cannot push more light out of these emitter without burning them.
Battery:
It had an unconventional battery - a single 4V Lead-acid. Very rare choice of battery - normally for LA batteries standard 6V is used. You cannot swap it with a Li-ion and expect the charger to work. You will need major conversion - 18650 holder, new charging socket both male/female, and a new Li-ion charging board.
In my opinion, too much work, not worth modding. You can easily grab a cheap XRE/XPE headlight for under $10 nowadays. For bit under $20, you can get XMLs And if you can spare $30, thereās a Crelant CH10 offer now which I think is a great value.
Hope this helps.
Yes, I am thinking of getting a nEw one but I need to know the complete specs of flashlights before I go for buying oneā¦
ALso, can you tell me here :
1) You say 20-30 Lumens. Is it for the whole entire 12 LEDS or a single LEdā¦ Also, One Guy on the top said assume 80 Lumens as a whole ā¦ how do u say or get to it.
2) It says in the Specs that Cahrging Voltage is 90V ā240 V and Charging Current is AC 0.08A and 0.5Wā¦ If I do the math with P=VI; then P should equal to ~ 220V * 0.08A = 17.6 Wattsā¦ not 0.5 Watts as in the Specsā¦ What is wrong around hereā¦ can anyone explain it to meā¦
3) If you can show me your repairs or photos of yours with the battery and all would be greatā¦
waiting for your reply anxiouslyā¦
Bigger battery just lasts longer.
Thatās the h (hour) in mAh 
wow
1. That was an estimate for the whole light. I fixed the light, tested it, and returned it months ago. My estimate is based on that. Feel free to give or take 50% or something as this is based on memory. But pretty sure it does not come anywhere near 80lumens.
2. Again, you can should drop your belief on Chinese spec. You said it yourself, the maths donāt add up. Youāre right. That means spec is wrong. This happens almost 100% of the time with cheap chinese light. Donāt pull your hair over it 
3. Sorry but no photos. It was not my light and it was returned quite some time ago.
1) What do you mean by LA Batteries over hereā¦ for that is LA used or howā¦
2) Can a higher Battery make the LEDs Glow more or they would fuse out (in general)ā¦
3) What is the Voltage Drop for the 5mm Chinese LED like that.
4) Also Now I am thinking of buying this Flash Light from the same COmpany. IT says it is 5W and 4800mAHā¦and a single Led. WHat type of LED could that be.?. Page Not Found - Aliexpress.com
5) So, what are ur views on this New DP LED 760 WHich I am thinking of ā¦?
Based on the above: don't buy it, buy a real headlamp.
For 30 dollars you can buy something really nice, for inspiration, check www.fasttech.com, search for any headlamp with a Cree led, there are a lot of headlamps that run on 3x AAA batteries, those are really common and you can use regular rechargable batteries.
1. It's just one of many types of rechargeable batteries - LA(Lead Acid), Li-ion, NiMH etc. Each types normally has different charging requirement, cannot be mixed.
2. No, higher capacity will only give more runtime. Higher voltage battery (e.g 6V LA) will make it go poof.
3. Vf for cheap emitter normally just slightly lower than 4V.
4 & 5. Why are you partial to this company? Those cost only $10 around here, and that's retail. No way I'm paying $30 for it. All plastic, generic emitter, battery of unknown origin, WEIRD SPEC - first it's 5W, scroll down and it's 3W - also "GREEN" body and later mentions black.
The Crelant I mentioned will beat it to pulp in everything for same price.
If you really want a good $30 value for money, by my opinion, it's would be this $6.50 headband, an XML C8 on top (ebay/Ali $10), and a couple flooders on the side ($3 cheapie host + $4 XML emitter). That's my current setup, and I never want to go back to single headlamp.
