Mr. X:

I just recieved my crelant 7G9 i’m very disappointed. It has a nice tight beam but it’s way too dim it’s clearly not 1100 lumens. It won’t throw more then 200 meters. Anyway i well be returning it for a refund.

Either you have a defective model or you set your expectations too high. It was measured by TurboBB to emit i think 1011 lumens, and has lux readings of around 65k (measured by selfbuilt on his review).

But by the sounds of it not throwing 200 meters I’d say you have a defective model.

Selfbuild has lux reading of 55 and lumens reading of 850, go look again. But yeah i have high expectations on every light i buy. I already return 3 lights :bigsmile: : olight m3x, eagletac m3c4 and now crelant 7g9. They all can’t throw more then 200 meters.

even at 55 lux, it comes to a min throw of a generous 400 meters. I doubt your measurements are accurate to begin with for each light you have returned. My 7G9 clearly abolishes the 200 meter mark.

I do measurements using google earth dont know how accurate that is. when i tested out the light it was not pitch black. There was street lights around. Could i ask you, what 18650 do you have?

Well now your talking… at this rate your just gearing yourself up for a huge disappointment when your TN31 arrives. There are several batts out there that will drive flashlights to their max potential. I use XTAR batts and find they work really well. I alternate between protected and un-protected. I currently have Panasonics in the mail rated at 3000mAh at 3.7v

I have panasonics rated at 3100mah at 3.7v by orbtronic they last long but i think they dont drive my flashlighs to their max.

Looks like I got the lux readings wrong, but TurboBB’s readings show 1040 lumens and 57k lux

I don’t know why your lights aren’t throwing more than 200 meters, but to have such bad luck… one cannot help but question the owner’s testing methods.

Google earth underestimates distances by a long way by my findings. i paced out my street from my house to the bottom of the road. it was 150 yards, google earth measured it at 90…

agenthex · September 21, 2012, 7:36am

Google earth can’t underestimate distance. It’s exactly as the crow flies.

blitzwing · September 21, 2012, 1:47pm

Any love left for the good old Solarforce Pro-1 running a couple of 18650’s? IIRC that does around 55K Lux. I love mine.

Jinx · September 21, 2012, 1:50pm

You must be using standards different to everyone else or something else is wrong, ANSI standards all those lights will do 200m easy

Jinx · September 21, 2012, 1:52pm

Double check mate, no disrespect but I’d trust the google earth reading above most others methods when there’s that much difference! How did you do your measurement?

Jinx · September 21, 2012, 1:55pm

Got mine on a gladiator running all 4 cells, it’s a great bit of kit but really needs to be driven harder. It’s outclassed when put in its price bracket.

When I test a light I take it to a football field at least I know it will be exactly 100 yards…. When the lights hit the outside fence 150 yards… When it hits the baseball field 200 yards, when it hits houses and people walking dogs, 300 yards …… When it hits the smallest tree I saw during the day and it looks an inch hi from where I am and its really 40 feet tall 500 yards …… Above 500 yards you need binoculars !!!

Checked out your youtube video of the flashlight collection you have…that’s some pretty good collection you have going.
The last torch (SST) was enormous!!

my9221 · September 22, 2012, 7:03am

Very useful links! The TN31 is a must have light.

Jinx · September 23, 2012, 11:21am

OK, think the main chart is pretty accurate waiting some new lights to raise the bar now.

So ive added a couple of Modded slots into the lower chart. Suggestions please…… Must be an easy mod, links to drivers/emitters appreciated along with a estimated Lux value.

Edit, Added Ledsmoke and Manny’s suggestions for now, other suggestions still welcome

Slewflash · September 23, 2012, 11:35am

When I get my TF X6, Ill measure stock and then modded lux.

Ledsmoke · September 24, 2012, 3:55pm

Modded lights. You're on mate ;-)

Trustfire X7: Bought on ebay. 50 euro

Opened the led hole in the reflector bottom up to 15 mm with a little round file. 5 minute job and then 15 minutes getting the debris off the reflector without touching it with anything but warm water and compressed air.

Changed SST-50 led to:

LED-tech T6 on copper core star: with original 3 mode driver running off 2 batteries: 80 kCd

Note that the link is to a U3 bin XML on copper core pcb since they no longer do the T6.

DX.com T6 on copper star: With original 3 mode driver running off 2 batteries: 104 kCd

The led stars were lapped flat onto the light and clamped down with thermal epoxy and screws.

I tried only these two because the second one is so good that I do not want to run the risk of going lower again. But I think the variance in emitters and mounting makes it worthwhile to buy several and test them. The base plate of the DX one seems to be fairly pure copper. It is very soft and apparently quite good at transferring heat.

Slewflash · September 23, 2012, 12:14pm

A stock X6 is around 1500 OTF lumens with around 80k lux already (6.5 amps).
I think at 9 amps it should be close to the 100k lux figure (I hope). But we won’t know until I receive it!

Ouchyfoot · September 23, 2012, 1:22pm

I figured my old Fenix TA21 was getting a little long in the tooth so after a long bout of indisicion and flip flopping I finally ordered the Xeno G42 v2 neutral. It’s in the mail…can’t wait.

ILIKEFLASHLIGHTS · September 23, 2012, 1:32pm

I doubt that a stock Trustfire X6 will produce the same amount of OTF lumens that a SR90 will. That’s about what a SR90 is said to do realistically or 1400 lumens. And a SR90 puts out about 113,000k lux @ 1m.

Slewflash · September 23, 2012, 1:43pm

I just read it here.

I don’t doubt it, because if you think about it, for an SST90 it’s not hard to output 1500 lumens. According to this it only takes 5.4 amps to the LED to produce 1500 lumens, and the X6 has a 6.5A driver, so if you take away that .9A (which gives you an efficiency of 83%) then it looks quite plausible that the X6 will output 1500 lumens or more.

EDIT: The SR90 has a head diameter of 100mm while the X6 has one of 80mm so you can understand why the lux is lower on the X6.
