My new torch

Should do. I run them in mine.

Thanks.
Are these 'protected' (whatever that means?).
Do I need 'protected'?

Discussion of these death batteries is similar to a 'What Chainsaw' thread .

Be warned that on independent test the Convoy S2+ came out as 460 lumens, a long way short of the nigh on 1000 lumens claimed.

Without restarting an old debate, that's one of the reasons why I buy the brands I do buy. Because if they say 900 lumens, that's what I get. In Chinese lumens that'd be about 3000.

That doesn't worry me, as I said in my original post asking for guidance:-

".... I'm off on a trip to the back of beyond and so I need another torch.
Something slightly lighter and smaller which doesn't have to be nearly as powerful
but should have a very good run time when set to a moderate output ....".

As long as you know what you are really getting for your money and are happy, all good

At the price of the Convoy its getting on for disposable anyway. No heartbreak if you lose it.

Nope not protected. But that is what makes them fit most things and give the performance they do.

I have nothing against protected cells, but it's well worth reading up what a protection circuit does and why. Generally you find them on ICR Li-ion because they can suffer thermal runaway. As far as I know INR/IMR Li-ion, while still containing huge amounts of energy, they don't suffer the thermal runaway, so generally (99% of the time) do not come with protection circuits.

What independent tests? Do you have a link or reference? As that sounds very wrong. Suspect it was either a rigged test, or they tested a lower output variant (you can order them with different output drivers).

I own lights from lots of different makers. The Convoy's perform as well as any of the premium brands. Have photo's and done lux tests that back this up.

And right on que...

Yes I have seen the results. No I don't know if it was rigged (doubt it though) and yes I'm sure yours is just awesome. However with a predetermined closed attitude as you have just displayed i could post a link to Jesus himself holding it and saying it's not quite as bright as described and you'd still rubbish it, so why bother.

Here have another

Which means you have nothing then. I'm more than happy to look at test, but as appeared from your earlier post, you looked to have an agenda...

And when people claim somewhat extreme (high or low) numbers against a known quantity, it is usually the result of some error in their test or a complete misunderstanding of the items under test (often by the 3rd party quoting the figures).

The driver in the Convoy uses 7135 chips to regulate current and is a pretty simple linear driver. With more than acceptable efficiency.

The top 7135 x 8 chip driver pulls a happy 2.8amps at the tailcap. For it to then produce only 460 lumens as you are claiming, would make it one of the worst performing LED drivers in terms of efficiency in the past 20+ years. Which is just isn't.

There are also 7135 x 6, x 5, x 4 and x 3 drivers. The lower the number of 7135's the lower the amp draw on high. By your claim, the lower ones would hardly be lighting up, which is again not the case, as loads of people have them.

I suspect the reality is, a 7135 x 3 or 4 driver was being tested, or the light was faulty, on medium mode or something else.



So why not post a link to this test please.

^Wot he said.

To quote from the Convoy S2+ page (the official Convoy store):

Convoy said:

7135*3 output current 1050mA
7135*4 output current 1400mA
7135*6 output current 2100mA
7135*8 output current 2800mA
the bigger current ,the brighter and hotter flashlight

So whilst I can buy into a lower number than the top output quoted if picked up with certain drivers, I struggle to buy the sub 500 lumens quote.
And it's far from empirical data but I own two, and both are comparable in output to the range of 900-1000 lumen lights I own.

Cant find the 480 one right now (at work so might have it i my home computer history file) but here is one saying 700 not 1000 that I've read before and had on work favorites. And it was stepping down to 480 with a slight discharge on the cell IIRC.

But you all carry on. 1000 lumens my arse.

Edited to add I've just bought one. You lot and your eulogies must be catching

Guys, just a quick one, I'm looking at buying this;

http://www.banggood.com/BLF-A6-XPL-1600LM-7-4modes...

Im a battery noob. I see it takes 18650 batteries. Until now, I never knew these existed. I'm old school (AA, AAA etc).

It doesnt appear to come with a battery. So do I need to buy the 18650 battery, plus a charger as well? Or can I put standard AA battery in? I understand putting an 18650 into an AA only device may cause faults or safety risks, but can you go the other way, and put AA into 18650? I'm not bothered about battery life, I have an infinite supply of AA's at work. Will light output be reduced by much using a AA?

AA and 18650 are not interchangeable - they're completely different sizes and outputs.

So yes, you would need to buy an 18650 and appropriate charger and that is a good thing...

(Contrary to the photo note that it is only one battery there.)

After much deliberation, and deciding on AA, I've gone for this

Bung a 14500 in it (li-ion AA) and get an appropriate charger and you'll notice a real difference in output. About 2-3 times output usually, and visually it's a noticeable increase.

hey guys
my dad has asked me to find him a decent torch as a christmas present.
he used to use something like this



but want to get him something better than that, don't mind paying more for a decent model.
only requirements he's asked for is that its rechargeable rather than using batteries

no idea about torches so and advice greatly accepted
cheers

[tenohfive]

Budget?

[dunning]

£50ish, didn't really think of a budget tbh, happy to pay a bit more for a decent one or if there's a good one for less then even better

[dunning]

Saw these 2 listed on hotukdeals
Are either of these worth getting or is there better alternatives? Only issue is he wanted a rechargeable one

Thanks again
