1Lumen: Latest news: Big GAW and latest review: Fenix LR80R

Hi, 

 

I just wanted to start a thread where people can chime in, and see what's new and for discussions instead of starting a new thread for every review we do.. 

I hope that's easier this way...

 

News June 2022:

We reached 400 reviews, and will celebrate that with a large giveaway on YT!

Subscribe to our YouTube channel and turn on the notifications to join when the GAW starts: https://www.youtube.com/channel/UCn0O0D7-tFiWN8dG2iQgdyg 

The giveaway will start around July 1, and follow the instructions in the video to enter. 

Due to so many companies sponsoring (over 20) it takes a bit longer to get this organized. Stay tuned

 

So far, we already have 5 manufacturers (edit: already 21 sponsors, and counting) on board with a flashlight (or a charger in case of Xtar) they sponsor for the giveaway!!! 

And a couple more are still in discussion! 

I expect to have about 7 flashlights (Scratch that.. we are already at 22 flashlights to give away)... Nope.. even more now!
so if you want to join, make sure you hit that like, subscribe and notification bell on our YouTube channel.

Wow, 350 reviews!

I've only done one review of a flashlight, though I plan to do another pretty soon.

Also, in my one review, I made zero measurements and took zero photos.  :FACEPALM:

Thanks guys. 

I think we can get to 400 before the end of the year... must be doable. 

 

I'm also trying to get into video reviews... but boy, that's a different kind of hobby Big Smile

Congrats for the milestone!

I always enjoy your reviews and most of the time I jump right into the performance section, the runtime graphs are well put together and easy to read. Thumbs Up

Spec: 21,000 lumens
Measured: 13,000 – 14,000 lumens
Your verdict: Insane lumen output (as a positive)

30% under spec, ‘insane amount’ as a positive, when an ec06, which costs much less, absolutely destroys it? 1/2 the advertised candella.

Are you trying to make people distrust your reviews on purpose, or is it an accident?

Thanks for the comments.

 

Gabriel thinks that 14,000 lumens is a lot of lumens, and I agree, although I would probably have just said: High output, instead of insane lumen output. But I see that you disagree. And that's totally fair. 

At what point would you say something is a high output? 50,000 lumens?

 

I do understand that for some, 14,000 lumens may not be impressive. But not everyone is used to 10,000+ lumens. 

 

The whole review is pretty clear about its performance, including the pros and cons. And again, in the final verdict it's repeated that it's not up to specs. 

We share all of our measurements in the review, and try to be as consistant as we can.

So, what is it that you don't trust?

 

edit: changed 13,000 to 14,000 lumens

Great review and congrats on 350! I don’t think I would have bought the MF01x if if I read this first… Oh well we will just have to see. Some other people seem to have a problem with screwing on the tail cap/ getting it off… May have to return this one…. Thanks for all your work

Our pleasure! 

Yeah, that's why I have repeatedly said that Groupbuys should wait until a proper review is done. But I'm talking to the wind here Big Smile

If the light was made with the help of BLF members, you can have confidence to get what you expected. 

Group buys of untested lights? That'll always be a bit of a gamble

I also stopped for a moment after reading “Insane output” listed as a positive attribute. It took me a moment to grasp what the reviewer meant. In my opinion the reviewer should have taken the design or potential of the light into consideration. For a Flashlight with 18 emmiters, powered by 3 21700 cells, rated at 21k lumens, I think most folks here wouldn’t consider 13k to 14k lumens to be insane output, especially when it’s so far below the rating. I think the comment is a little misleading and could have been worded more clearly. That said, I don’t see anything that would cause me to mistrust the review.

Thanks for the review. At this point I’m glad I didn’t order this light. I wanted to wait for feedback about the unfamiliar LEDs, had already bought the EC06, and GITD stuff is not my thing, but the 30% under spec output is an absolute deal killer for me.

I feel sorry for people who don't have a hobby or interest to escape to.

Yeah, I can understand that about waiting for a proper review. 

Okay, I just went ahead and changed the wording a bit, so it wouldn't trigger anybody... 

 

Still, we have to keep in mind, that it's not just what the manufacturer claims, (although that could influence the final verdict a little bit)

 

If a manufacturer claims a flashlight is 200,000 lumens, but only does 100,000 ... it's still a fact to say: Extremely bright. Even though it's 50% below claimed output.  

Calling something bright is subjective maybe? Big Smile

100,000 lumens IS extremely bright... or not?

 

So the question is: when are we allowed to call something bright? extremely bright? 

lol

In the end you can’t please everyone.
In this case i might add a slight clarification, its insanely bright even if it doesn’t meet manufacturer spec.

After that leave those who want to grumble on their own.

I have never seen a 13,000 lumen flashlight in real life and 8 × 100W bulbs in one flashlight would be insanely bright to me when i do someday see one (at present my brightest light is my 4000 lumen Convoy M3C).

I just replaced my car headlights yesterday to restore a staggering 3,000 lumens of halogen light. I look forward to seeing how much of an improvement it is at night and if it had 13,000 lumens i’d probably be arrested for blinding oncoming drivers.

Pardon me kind flashlight reviewing sir. I was wondering if it’s possible you got a bad light? I read your review and did see you recharged your best batteries and all that jazz and they still didn’t budge from their numbers. I ask because I saw another reviewer that got 23,000 plus lumens on theirs. Could something in the light be restricting/subduing the power or maybe just limiting it to a single battery? I know different reviewers have different readings, but this one seems like a massive difference and may it’s just that it’s a dud? Just wondering if this has already been checked out and discounted. Thank you for the review and congrats on number 350. Party

Thanks for the feedback on the “insane lumen output” comment, that has now been re-worded. As much as I was disappointed by it not hitting spec, I guess I was still impressed by 14,000+ lumens. I’ll be a bit more careful in my choice of adjectives in the future.

Re: possibility of having gotten a bad light. It’s possible, but everything seems to be functioning properly. And the batteries were testing properly with low internal resistance and all drained down consistently over the tests, so I think all cells were being used properly. I tested and retested so many times (and used different testing setups) that I don’t feel like there were any major flaws with the testing process. I’ll be curious once more of these get into peoples’ hands what they observe.

Still, I’m wondering why the output is so low compared to the rated output.

Maybe there’s some resistance in other components that weren’t a problem in the prototypes, but due to cost cutting for production, they used higher resistance stuff?

That is definitely possible. Any little bottleneck in such a high current light makes a difference.

Agreed, every little bit of resistance adds up and with this much current, could have a significant impact. With this high of a power draw, running the cells in series instead of parallel would probably give you better performance, but then you give up on safe internal charging and it generally makes things like driver design more complex.

Well I tested the EA01 when it came out with the xhp50.2 6500k and came put lower than other reviewers. I saw max like 3600 or 3700 lumens and others were consistently over 4000 on a 30T. I tried different batteries, even different luxmeters and still couldn’t crack 3700 Lumens. I was still over the 3500 advertised though. Just goes to show that you might get a good FET, solid solder joints, a good bin emitter, properly applied thermal paste, aligned optic/reflector, etc, etc. All those can affect output to varying degrees. At the end of the day these are low-cost lights that don’t benefit from exhaustive factory testing like more expensive brands and you get the best cheapest of whatever Mateminco was able to get off the Chinese marketplace that day into the parts bin for that production run. Sometimes you win!

Indeed.

Let’s make our calculations at 100lm/W efficiency, right?

20000 lumens / 100lm/W = 200W.

200W/3.6V = 55A.

That would equate to 18A per cell.

With that much current, everything becomes a bottleneck:
Springs, contacts, board LED wires, MCPCB trace thickness, etc.

Say ChibiM, could you check if the springs are magnetic, just in case?
I’m curious to know…

That burnt spring suspiciously looks silver with the gold plating burnt…

Also, @Sirstinky, the difference is that you still got over the rated brightness Silly

This one was wildly under the rating Smile

I did a spring swap on a Ft02S a while back. They share that tailcap spring with the EA01 and FT03 I think also. Looks similar to other Mateminco products also…the outer, taller spring is not magnetic, copper alloy, the inner, smaller spring is magnetic (steel). I removed the inner spring and used a solder wick. I dislike that design somewhat because the spring pcb is really glued onto the tailcap and makes soldering difficult.

The Lumintop D3 I tested has a copper alloy tailspring

Bruh, they took the risk of not using phosphor bronze/BeCu on every spring lmao.

No wonder: at 18A, only a dual phosphor bronze/BeCu spring would allow for good performance, unless all of the coils were to touch each other.

I just checked with a strong neodymium. No signs of attraction to either the outer or inner springs. I’d say no steel present.

Bummer on the MF01X. I am glad I did not buy one, but I really wanted to. Hopefully they will fix.
