Spec me an LED Torch

This TN31 is AMAZING!

. Took it to the lakes and it was absolutely pitch black there due to no light pollution and this lit the paths up so I could see as good as if it was day. Also amazed at the throw, even with a bit of fog I could see well in front of me to see what was ahead.

I will be looking out for user reviews of that new Fenix TK75, if that really is 2600 lumens compared to this torch with 1100, it will be interesting to see how much brighter it is in the beamshot pics. If someone compares the two. I'm guessing the TK75 will have more flood with the 3 LEDs and what looks to be a shallower reflector.

Yeah your TN31 will beat the TK75 for throw the TK75 will be a nice mix of throw & flood, the head on it is huge.

You'll regret not going for at least a double bay charger.

Gonna grab a nitcore i2 next month for home this will be left in work for emergencies, couldn't find a decent UK seller with stock at a sensible price.

Also stripped down an old laptop battery got 8 what look like Sanyo's not sure if I can save them, laptops been sat unused for 3yrs - 4 @1.48v and 4 @ 0.80v

No, those cells are all junk and have to be tossed I'm afraid

Any Li-Ion cell that spends more than a couple of days at less than 2.75v/2.5v has to be discarded - you get metallic lithium forming around the electrodes which can short-circuit and cause the cells to explode.

Not worth the risk, just throw 'em

Out of interest, how can you check them and what's the best way to dispose of them?

Thanks will do don't fancy the risks, was hoping to get a couple out of it!

Multimeter to check the voltages.

Exactly.

Then, if they're above about 3v (ish), charge them up, measure them 15 minutes after they're off the charger, and then 12 hours after they're off the charger. If the voltage has sagged by more than about .1V, use them with caution, and if it's sagged by more than .4v, throw them away

JHeaton · 12 Nov 2012 at 21:42

Cool. I'm guessing there are designated disposal points for things like this, then?

Deluxe1 · 12 Nov 2012 at 21:44

Sometimes there are battery bins outside of supermarkets.

Aod · 12 Nov 2012 at 22:01

Ikeas especially! funny thing - most of the Cells that go into those bins get sent to china, where quite a few of them get repackaged into Ultrafire-branded cells

I've ordered my shadow VG20 from Intl-Outdoors too, and some holsters

Which holsters did you go for?

Deluxe1 · 13 Nov 2012 at 18:14

£159.95 for the TK75 which is cheaper than expected, chuck in the 8% discount and it's even cheaper!

Undecided on which of my big lights to let go in order to get this one, TN30 or TM11...

Any recommendations for a torch that I could get as a Christmas present?

I have a Lenser P7 and I think its very good, but would like something for my dad who's a hobby farmer. So something that can flood a large area over a distance would be good. Don't mind if its bulky, in fact might be better.

Say under £80?

Any thoughts anyone?

Deluxe1 · 13 Nov 2012 at 20:33

What battery type are you looking for?

Triggster · 13 Nov 2012 at 21:20

So long as you can buy them from the high street or even a rechargeable one would be ideal?

Just been out testing the 700 metre range of the TN31, seems it exceeds it even in non pitch black situations!

Beam shots to come :-)

Aod · 13 Nov 2012 at 22:26

Excellence! Looking forward to it Mrk

I was looking on one of our suppliers websites earlier today... I'm very sorely tempted to buy a 35w HID "torch". 'Specced to produce about 3500 lumens for over an hour Muahahahaha!

For the eye to percieve something twice as bright you need 4x the lumens, so a 2600 lumens flashlight vs your 1100 lumens flashlight will seem roughly 35% brighter.

I stopped chasing lumens ages ago - now more concerned with quality and function. Just about to plump for my 2nd Haiku.
