The Flashlight Nerd Thread

I have the original 3 emitter version. since it came out, all sorts of clones came out.

it is in the cheap chinese junk category so all bets are off on what you get with this.

but I have the first version, and almost immediately clones appeared (or is mine a clone no one knows)

a) it's fuggin bright on max, starts on max, untwist it to kill power (anodized)
so I like that feature (no standby current when untwisted)

b) on 300 lumens it whines a bit (cheap pwm)

c) it drains batteries pretty quick on high. but it does light up a huge huge space

I just keep it in the kitchen if the power goes out or there
is a boogeyman about I'll grab it. otherwise I use the quark mini in the kitchen

 

If I was @addicus24 I'd get two of these: http://www.ebay.com/itm/201423820117?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT

 

From the other Flashlight thread my EC20



And my 2D Mag

 

with many smaller reflectors, you get more flood than throw

also 15000 lumens is not possible in a 9xml, 4x18650 light unless you use IMR cells


I am of the belief that the 4x18650, 3 xml is about the best combo. the three xml's
can all be driven hard and you get decent throw since the reflectors are bigger. adding more emitters yet keeping
the same 4x18650 you get diminishing returns and flatter and flatter reflectors


[also...my sky ray 3 emitter is a real measured 2186 lumens]
----------------
from BLF on skyray 4x18650
3 led you get 7.5 / 3 = 2.5 amp per emitter

4 led = 1.9 amp per emitter

6 led = 1.25 amp per emitter

If you look at the Cree data sheets most leds are more efficient at lower currents. This means in total more LEDs while they will have more losses (more wire, etc).

Should in theory produce more lumens in total. It certainly won’t be less. Not at this number of LEDs anyhow. Driving the emitters less hard will also produce less heat. So you’ll probably get a more stable output assuming your batteries are up to the task. that is the issue, 4x18650 pushing 9 leds...it's a stretch

 

So maybe he'd be better off with this one:

SecurityIng® Golden Waterproof 3X T6 3000 Lumens LED Flashlight Bright Lamp Light Torch (18650 Battery Not Included)

http://www.amazon.com/SecurityIng®-...F8&qid=1445610896&sr=8-1&keywords=skyray+king

Same one you have I think.

 

yup. looks the same

can't tell for sure unless you open-it-up but that is 'the original skyray king, kung, whatever brand on it' bigasslight

 

I'm ordering one. I'll report back.

 

So with a light like the skyway, you can't just put regular over the counter batteries in it ? Or is it just convenient to have rechargeables. My job supply's me with all the batts I need.

 

It uses four 18650 batteries.

 

This is my EDC light. It's a Zebralight SC600 MKII that puts out 1100 lumen on high. I've beat the snot out of it, and except for the lense popping out once or twice it's held up like a champ.

I am however in the market for a light with a little better cooling. This thing gets hot if left on high for too long.

Single 18650

 

almost all 'high powered' lights and devices use 3.7-4.2 volt lithium 18650's


most all these high powered led lights do

all your laptop packs use them

even Tesla cars packs are made from hundreds of individual 18650's


the lithium 3.7-4.2 volt 18650 is 'the standard' for most high powered systems

there are others of course, like the tiny 10180 or huge 26650 but li-ion 18650 is ten times as popular than any other form factor

 

Thanks for that answer. I have zero info on this I've always used big ass mag lights.

 

All of the newer LED lights will make your old Mag lites look like candles.

 

Yeah pretty impressive number. Actually looking at the voodoo set up with mount.

If I were looking for a hyper-light on the cheap I think I would pick this up: http://www.batteryjunction.com/olight-srmini-ii-xml2.html

 

That's a great find, and it can be charged in the truck.

 

Exactly, only it's a pre-order deal. I'm going to call and find out how long until it ships. Be back shortly...

 

lights that can sub 2xcr123's for 18650 are pretty useful as you can store cr123 forever they barely lose a charge

I carry a thrunite tn11 in trucky and 4 loose cr123 in the cubby

you can buy them in bulk from battery junction for less than a dollar each (titanium innovations brand)

OR in an emergency pharmacies and camera stores carry them, but they are ultra expensive if you get them in a store

so, keep an 18650 light and charge the 18650's when needed
and if you are in the boonies and deplete the 18650's, go fetch your
pile of cr123's you stashed and they will be good to go when needed


full disclosure on what I roll with:

in trucky I carry 7 lights

-thrunite tn11 with 2xcr123, and 4 spare cr123

-fenix e11

-some cheap plastic headlamp with 3xaaa

-my keychain Helix Zi

-a red light built into my mini swiss army knife

-my phone has a build in led light

-a homemade 12v XML floodlight with two big clamps for the truck battery power, hard drive magnet base, and 50 feet of speaker wire.

 

I love it!!

In my 4Runner I carry:

Nitecore MH25 and NDF40 diffuser with kbvoodoo mount in center console.

Nitecore MT40 with one-off kbvoodoo mount in rear cargo area.

Nitecore HC30 headlamp in center console.

Nitecore Tube keychain light.

Two extra Nitecore 18650's in center console.

Two generic CR123's in center console.

And a cheap USB charger in the glovebox.
