How Many Lumens Do You Guys Think This Light Is

I have a Coleman 137 lumen light and I would say that it is very close to that rating. This light above is probably at least 6 times brighter and maybe 7.

Hard to tell from pics. My brightest light is about 600 lumens and that looks brighter. But my counter-question to you is... does it put a smile on your face? I'm sure it does. That's really all that matters. In my experience most people are impressed by light output rather than a lumen number.

I compare it to drag racing cars. It doesn't matter how much horsepower the owner claims his car has, if two cars race one is going to win and one is going to lose. If the guy that lost claims he has more horsepower than the guy that won, guess what, he still lost.

Here's what another guy told me.

Comparing the screenshot to my Fenix TK41, your light certainly looks >800 lumens

Hey thanks. Your right. I honestly think this thing will beat 800 lumens very easily.

Here's a shot from my KEYGOS 1600 lumen 6X Q5. This was just with 2 18650 batteries in it. If I put the extension on it and add another battery it will beat that.

I know a little about lumen output.

I have seen a Catapult V3. And up close I think this thing will beat it. It definately won't throw as fine of beam as the Catapult.

Ok just took this one of the KEYGOS 1600 Lumen 6X Q5 extenstion added(3-18650's).

That last street sign is about 220yds. No problemo.

Here's a tree shot.

Here is how i see it, If you can look directly at the emitter and it blinds you then your light is darn bright.

Judging the brightness of a light without being under scientific controlled and measured conditions is just a bunch of guys sitting around telling fishing tales.

You overpaid on the first light as im sure you know, But your here now learning how to buy good stuff cheap. Or like me buying mediocre stuff at average prices as i dont know any better.

I do think i can convince someone my ITP EOS A3 is run on plutonium now i have a 10440 IMR cell in it.

Again... the lumens number doesn't matter at all. Do you like the light? If yes, keep it and be happy. If no, sell it.

If you just need a lumens number to brag to your friends... why not just tell them it's 2000 lumens, or 20,000 lumens? If you own the light and have no idea how many lumens it is your friends certainly won't know either (unless one of them is a flashaholic). Heck, might as well say it is 20 Trillion lumens if you are just going to guess.

I'm not trying to be a pain but the fact is there is not a person on this planet that can tell you how many lumens a light puts out by looking at a photo. It's just not possible.

You can't estimate just by looking at photos. The people who claim to are just making up numbers. You need to measure power consumption or actual output.

I ran the numbers on my 5xLL Supercomputer and fed in a scan of the pic also and it is definitely 4.9238473 Lumen's. But then again i haven't calibrated it to read Chinese Lumen's tho.

I know it was harsh for you to get banned on cpf, and by 'warned' they often just mean had older pictures removed etc which can be missed. They can be pretty stupid with banning and suspending people over there. I posted yesterday asking about opinions on a good deal I got for something and they just removed it, no reason given why even though previous posts of a similar nature were left alone.

But I will post what I said there again: The light has been measured in an integrating sphere by someone to be 580 lumens I dont care if this is less than 1200 and you previously thought it was amazingly bright and so must be around 1200. you have to remember 580 OTF lumens is a lot of light. Combined with the tight beam allowed by using XR-E leds to make that will give it a high peak beam intensity and appear very bright. It is not really anywhere near 1000 true lumens however, almost all of the cheaper chinese manufacturers inflate output ratings a lot. The 3x XM-L light I mentioned claims 3800 lumens to the 1200 claimed by the 5x XR-E one, neither of them actually are that powerful; they have been measured at 580 and 1600. But they are still both very powerful lights.

This isn't a bad thing, you just need to readjust your thinking of what numbers correlate with what brightness. Think of it as meaning that there are many more options out there left to try which are now brighter than you would have imagined before.


Here is a picture of the light you showed and the 3x XM-L light I mentioned both shone against a wall next to each other:

It's often hard to judge brightness by eye, are you judging by hotspot brightness (intensity) or shining them at a white/pale ceiling one after the other and comparing the amount of light on the floor? That second way should give a much better indication of overall brightness.

The problem is that pictures can't really show comparative brightness unless both lights to compare are in the picture together or the two pictures have been calibrated so they have exactly the same camera settings. You certainly can't compare what a picture shows to a subjective comparison of how bright something else is in real life.

With regards to a 55w halogen, the fact that this light is so much more focused makes it look more powerful. It may match or beat the beam intensity, but not overall lumen output.

I would stick up for you on the banning front, but you are being very frustrating just ignoring what many people have told you and insisting slightly overexposed pictures 'prove' your light must be a solid output amount. Maybe your light is overperforming and is a bit more than 580 OTF but you can't tell by pictures.

If you really want an accurate guess at what yours is putting out you have to use a DMM to measure current input from the tail. Then we could work it out, but please stop asking people for subjective opinions on how bright it is from pictures.

As someone else said, it is great you are pleased with your light, that's the main thing. But if you want to really find out what it outputs you have to actually do some listening after you ask even if the response wasn't what you imagined. It really isnt a bad thing the output isnt as high as youd previously thought, the true amount of lumens is the same as ever, it is just as bright a light as before, you just now know there are even better and brighter options to choose from in the future. That is maybe a little annoying I guess, but really not such a bad thing.

Hey I appreciate you guys responses. And I understand what you are saying about lumen output. And I also understand there are better lights to be had.

I have 2 of these lights coming. I don't know how bright they will be but for the money I thought they were a good deal.

Tell me what you think of this light.

This will be a good light and brighter than the other two lights put together.

Hey thanks. Then I should be really happy. Heck I'm tickled with the other lights I have got lately except one that didn't work right due to a faulty switch. But I did get a full refund on it and got to keep the light. So I ordered another tail cap and switch.

Sorry I have made a mistake, i thought this was a question from another member about a zoom light. This light will be on par with the first light but will run cooler than the first light.

Only 1600 lumens from a 'T6"?

And the 'Trustfire T1' has gained a lot of weight.

This is a Trustfire T1.

Got one of them today. It'sa big joke. Nowhere near as bright as my other 5 bul or 6 bulb models.

That light should have a bit more throw than flood and that can be deceiving at times trying to judge its lumen output. Shine it at a wall from 1 or 2 meters/yards and it should have a pretty small hot spot with some decent spill.

Every light has its pro's and con's and sometimes its easy to judge a light before you get to understand its strengths.

Now in saying that you may want to try your hand at modding and experimenting to make the light do what you want. Not everyone can desolder a driver from the pill and add extra 7135 IC voltage regulation chips, But you could put 2x 18650 IMR cells in it which may boost its amp output by a decent amount without endangering the light. But you get less run time since they are 1500mAh cells usually.

This is gonna sound dumb, But try putting two matched cells in it that both are at 3.5v and see what happens. If you can take tail cap amp readings you would see the driver starts boosting the amps to the emitters as the cells start reaching 3v and their cutoff points.

I have a 4x AA Small Sun XML light that looks weak when shined at a wall at 2 meters because it has a hot spot the size of a golf ball thats as bright as the sun in that tiny area, But take it outside its a completely different light.

If you feel you have the knowledge or the willingness to learn you may want to take a peek at the "Flashlight Modding and DIY Parts" section and you can learn to test your lights in almost any fashion and also how to mod them to be the light you want it to be.

My two best mods are these:

1. UltraFire WF-501A shorty with an R5 pushing 2.3A with an extra 7135 IC and running on a 18350 IMR cell and thermally enhanced. It gives my full power 3A XML single emitter lights a run for their money and is a bit over half their size. A true pocket rocket.

2. Olight M20s i molested and put an XML T6 into it with a 3A driver and an 18650 IMR cell that now pushes 3.5A's

So now im never disappointed in any light i buy, I look at it for what i can make it into. And what i do doesnt take serious skills either.

Well I guess the batteries weren't fully charged. It works great with the ones I put in it now. Not 1600 lumens, but it throws a nice bright beam. So I am happy.
