All in all I have run it for an hour. Not straight for one hour. The brightness didn’t really impress me, I have no real way to measure it.
The specs for the price are still good if you look at other brands like LED-lenser similiar output for about the same money but this is built better.
Agreed, but not a true budget light and not a good mod candidate. I have tried fairly hard to open mine and it is just glued to well. I have not tried placing the head in solvent yet, may be the next step. Has a very good beam profile, just needs more lumens and a good driver.
I think for a single AA battery the light is on the higher side being 190 lumens. Also to do this the driver must be good from a single AA battery maybe using a different emitter you could probably squeeze out a few more lumens….
Being glued its not meant to be touched i guess. Maybe gluing it makes it more usable from a IPX rating perspective. I gave my mate some hugsby XP1s to use and he has broken 2 of them already by dropping them. I took one apart and it was the boost converter circuit the transformer breaks of. Maybe gluing the head gives it extra strength…
Hello Hank,
Thanks for your review and suggestion about our T11. Here are my answer for question,
1. Why we need reviews on Amzon?
It’s according to Amazon training course and searching rules.There are a large number of American make Amazon reviews for living.
chinese sellers have to do it……
Our company thought BLF members are flashlight specialist, so hope get yours reviews and suggestions to updating our light.
2.About paid $5
We have to say we never want profit from it,our shipping fee is already higher than $5.
3.About change reviews.
Sorry for this problem, 4 star is OK. But it’s really not friendly that write under our light you only paid $5.
What would other consumers thought about T11?
4.TN4A bogus?
We admit our Amazon colleague is newbie. BLF members who have made our WR10 reviews know we even don’t know how to set right Amazon code last time.
So we have corrected this mistake after your point it. Thanks your remind. :face_with_monocle:
Except TN4A and T11 are AA lights, what any other similarities between them?
Besides, we can sure next T11 version will can powered by 14500 battery, and hide strobe&SOS (or add memory function).
Sincere thanks for all members suggestion, OrcaTorch is more good at diving flashlight, but we will try to design better flashlight with yours help.
Looking forward to your review.
And I will feedback maybe forward switch is better.
Amazon allows sale at low price to people who agree to write reviews. That’s their official published review.
Someone who gets a product for $5 or $1 has to work harder not to be “bought” and write a fake review hoping to get a better price next time.
I tell the truth. If that means I don’t get offered a review flashlight next time — that’s fine. Because I try to write clearly everything that affects the review.
I am sure you don’t need to worry about “five star” reviews.
Look at this one:
https://www.amazon.com/LumiTact-Tactical-G700-TM-Flashlight/dp/B01DPS6LAG
Very mixed reviews. Grossly overpriced for a bad flashlight. Made in China. Sold everywhere under many names, always for far more than it’s worth.
Amazon is happy selling that sort of thing.
You need to get reviews, and it’s perfectly OK to give discounts to get the flashlight into reviewers’ hands.
Both Amazon’s rule and the US Federal Trade Commission rule say that the reviewer should clearly disclose how they got the product and that they agreed to do the review as compensation.
Amazon is trying very hard now to clean out their reviews and get rid of the “all five star” fake reviews they featured for many years, when they allowed paid reviews without question.
Amazon wants honest reviews that disclose negative and positive comments, and disclose that you gave a discount or something to someone who agreed to give you a review once they used the light.
Amazon wants to put an end to fake reviews being bought or reviewers giving all positive reviews in order to keep getting discounts.
I think you’ll do fine if you make the first version of the light an example — gets mixed reviews, you come out with version 2 and everyone can say, this one is better, they listened and fixed problems.
To show improvement, you have to first show honestly what the problems were — to show what changed.
BTW, 1.35 amps on high with an XTAR 14500… not bad and is considerably brighter. Does not get hot, so either poor thermal performance or just not hard enough driven.
Many thanks Hans, we just a little worry about when comsumer see you get it at $5, then they all want get it at that price……
Your review is really very good!!!I’ve translated it into Chinese to our engineers. 
Thanks, Keith, for the effort you put into your review. Looks like a solid light.
Was it any brighter? my jetbeam 1mk is about 190lumen with a AA, and 450 lumen with a 14500.
Robert, it is brighter… I would guess 50 to 60%, but no way to measure it. It does either have thermal or timed step down. I am leaning toward thermal… I am testing now for low voltage detection or shut down.
I haven’t tried the 14500 for fear of burning up the driver, but it’s looks like it was made for it if it hasn’t fried yours. If that’s the case, that puts a whole new dimension on this T11.
One more note, it does not have low voltage protection… so use protected 14500’s. The good news is that the longer XTAR batteries fit fine! My cell protection kicked in at 2.74 volts. I think it would have sucked it much lower, the output was still good and all four modes still worked. Ran for well over an hour in modes 3 and 4.
Now, I really do like this light. I would have still loved a lower mode and hidden disco modes.
Great news, thanks for testing that out. I’ll give it a shot when i get home
One thought — also sent as a PM to OrcaTorch
I highly recommend offering hosts — the flashlight without the LED and driver — to people at BLF,
and doing that as soon as possible, before a “version 2” design is decided by your engineers.
You can look us up on the system and see, so you’re not just sending them out to people who don’t have a record of improving flashlights.
I am sure that you would get back many ideas — not theories but actual proven built designs — using a variety of drivers and LEDs (and even switches, if you’re deciding between forward and reverse click)
It’s a solid little flashlight, there are very few AA flashlights capable of being modified that have significant mass to handle higher power/heat.
I don’t know what’s inside the light (I mean to ask the reviewer at Amazon who posted pictures showing the head taken off, how was that done).
Having a host (and several spare pills —- assuming it uses a “pill” to hold the LED and driver, and the pill screws into the flashlight head)
each of us could come up with several different arrangements, someone might make a copper pill for better heat, and so on.
Want to come play with us? It could be fun.
I tried the pm route, also asked about a host. Did not sound very likely to me…
So, I just received mine, also at a substantial discount and a full review and YT vid will be forthcoming as soon as I have some actual usage from which to base my opinions on.
Obvious first impressions:
- Nice build quality
- Blemish free reflector
- Perfectly centered emitter
- Pocketclip allows for moderately deep carry
- Expensive for what it is
I think this light is to “basic” for the price. You just get a basic AA light with xpg2 emitter, its not really tactical and a policeman or security wouldnt use a 1XAA light anyway. I mean whats the difference to a s2+ except the 18650 format? I miss a more complex driver, low voltage indicator, xpl hi, 14500 support, maybe a driver with several modes to choose from, firefly mode, maybe more color options like natural tan, olive, gold contacts etc… Ok, it looks nice but Klarus offer the Mi7 for 39 dollar for example.
I hope whoever posted the first review at Amazon is here, or finds his/her way here (hello?)
Because that one came without the glue and pictures are included showing it with the head off.
I’d like to know a lot more about the innards of the light — and whether it’s more like a high end dive light.
For example: would it qualify as explosion-proof (sealed to whatever that regulatory fire marshal specification requires for no sparks or heat that can set off an explosion if used in an area with flammable vapor/gas.
I’m just guessing that most dive lights would meet that spec, though I’ve never noticed one advertised as meeting that.
It’d take some formal testing, I guess: Policies and Procedures | UL Standards & Engagement
That would be a big plus for emergency bag use.
Ah, interesting, “explosion-proof” is also “dust-ignition-proof” — I recall that grain elevators do tend to blow up, and so do flour mills — any situation where the air is full of very fine dust particles that can be ignited, is a hazard for that. And a lot of things will burn as dust that won’t burn easily in solid form.
