Jetbeam RRT0 XML

[Warp]

I've no knowledge about S2 current draw...but into the 1x123 realm I would opt for:
1)HDS Custom Built Rotary 200Lm USD200 (I own one)

Or in compact 2x123
Quark "X" 2x123 (handles very well 1x17670RCR, has thermal protection)
Not rotary

Better bang for value?
EagleTac T20C2 MkII XM-L which has many output levels, thermal protection, upgradeable led/reflector module and many many goods into standard package. You can find it for less than 100USD. It is rated for 720Lm (480 Ansi FL-1 lumens) and mine eats AW's 2900 flat top 18650. Not bulky at all.

Bulky is relative. The T20C2 isn't a pocket light and compared to a JETBeam RRT-0 the T20C2 is, well, massive. It's a cargo-pocket light, perhaps.

Not stepping into a debate about dimensions. To me JB RRT-0 xm-l should be sold only as compatible and reliable with primaries. Bottom line. At 260lumens with no reliable or safe support for rechargeables to me it is a no go.

If you are unwilling to discuss how much larger the T20C2 than the RRT-0 is why did you bring it up and claim it is "not bulky at all"?

OP: To get the size closer, if that is required, with the same basic list of pros as the T20C2, consider a P20C2.

 

[JustG]

It's too bad I came across this thread after I ordered a RRT0. I had high hopes of running rechargeables in the light.

 

[Surnia]

JustG, I have a thread running in the battery forums about Li-ion cells pertaining to the RRT-0, and 45/70 has a good reply on the subject. Not all is lost, so there's still a good chance of hope for the RRT-0! As daberti says, just don't run it on max for too long as the 16340 or 14500 are rated to 1.5A max (and according to 45/70, it'll just shorten their life with the high drain)

 

[JustG]

Surnia, thanks for the heads up on the battery forums. 45/70's words are reassuring.

 

[Moriarty]

I run mine on an AW RCR123 and work on the basis that 'maximum' is only intended for short periods of time.

Used sensibly, it gets warm but not hot.

If I need circa 500 lumens for a long period of time I use an RT15 XML driven by two AW 18650's.

Don't get me wrong Warp
First of all let me correct myself: T20C2 MkII XM-L delivers 580Lm (Ansi) and not 480 as I wrongly stated above.

Then:
T20C2 MkII XM-L specs

	Body diameter	1.0 inch (2.54cm)
	Bezel diameter	1.3 inch (3.3cm)
	Length	5.5 inch (14cm)
	Weight	4.25 ounces (120grams)

RRT-O XM-L specs
Body: 20.5mm
Head: 25.4mm
Total length with extens. tube: 116mm (I consider this as its max length and please note that at less than such a length there are VERY GOOD 17670 capable hassle free XM-L flashlights around)
Weight: 83g (with ext. tube without batts)

I inch longer and 1/3rd" greater bezel don't make it a one order greater and beefier device.
Admittedly weight might be.
But it is a true tactical, reliable, thermally managed, upgreadable, weapon mountable flashlight (heavy recoil ready) and there is evidence that RRT-0 XM-L it is NOT.

The RRT-O is small enough to be a pocket light.

The T20C2 is not.

Holding two lights of those dimensions side by side, let alone putting them in your pockets, demonstrates this conclusively. Sure, the T20C2 is a fine light. But it is not a pocket light and it is a different size category than an RRT-0. That's all. Saying otherwise is, IMO, grossly misrepresentative and the last thing I want to do on CPF is mislead somebody into spending $90+ on a light that doesn't meet their needs.

I have a T20C2, as my signature shows. I even carry it in my cargo pocket at work and at night, etc, but it is purely supplemental as it is far too large/bulky/obtrusive/pointy/etc to be a true EDC/pocket light, which is all that my point was meant to confer initially.


Also, why do you bring up weapon mountable? The OP never said nor hinted at anything like that.

Sorry, you look like not getting the WHOLE picture. I.e.: actually RRT-0 XM-L is not even worth being bought. Too much issues with RCRs no thermal protection and low voltage cutoff (thus no safe IMR usage). Period. JB endorse usage of cells that can actually be dangerous (RCR) or costy (driving IMR dead).
I'd like to hear from you something about this.
Then: why spending more for getting less? RRT-0 xm-l is sold at USD102 while Eagletac at less than 90USD...go figure!! More for less means also that if you're paying less for a flashlight that is weapon mountable and heavy recoil ready...even if not initially planned...why not?

The only safe usage of RRT-o xm-l is with primaries but then it delivers only 260Lm OTF with a draw of 0.85A (wisely enough). Period.
But in the same form factor comes the Ralight Rotary 200lm. Better spending 108USD on RRT or 200USD on the former?
47's Quark "X" (XM-L as well) 123x2 is even shrter than RRT-0 with extension tube and can even use 17670. And costs way less.


If T20C2 is so much longer to EDCing is a matter of dressing (clips combat grip and so on can be easily taken off BTW). If it is safe and offers more you could write it on marble
And safe are 47's and Ralight.

Talking about signatures: see what I sell and see what I recommended...just to guess if I'm biased....

 

[kreisler]

mine eats AW's 2900 flat top 18650. Not bulky at all.

your Eagtac T20C2 mkII eats AW 2900 with flat top? how come? the 2 plastic rings prevent contact:

The topic was a small light (RRT-0). A much larger light (T20C2) was brought up and claimed to be "not bulky". I disagree with that claim, given the circumstances/situation. That's it. It's very simple.

He probably removed the ring

 

[member 6142]

Nope. That came to my surprise but rest assured. It is true. No contact ring removed. Nothing modified.

 

[member 6142]

Warp keeping off from the huge eagletac. The thread talks about what someone else here defined as garbage. Come on let's face it. 108usd for it it is stealing to say the least. Or bucks for danger if you prefer. JB endorses usage of RCR out of specs. That's it and now at least every wise average Joe is warned. But me and you have a common view. Glock.

That is surprising. I had to remove mine, and not just for my flat top AW but even for my "button top" Redilast as it only worked intermittetly (sp?).

I have a 26, 19 and 21SF and have previously had a 20 and a 30SF as well plus I was, for a very short period, issued a 17. They are very nice.

 

[Phil40000]

Slightly unsettling results there, you would think that they had put a bit more thought into that. Thanks for the results daberti!

How well can LiCo handle short high output bursts? Its highly unlikely I'll ever run it at max for extended periods of time, but maybe for the occasional short bursts it'll be interesting...

Or maybe I shouldn't bother and just get an S2 instead =T


Phil40000 sorry if I came off as offensive about your posts regarding the dead IMR, its just a bit difficult to read results without numbers. thank you for doing the initial tests, and wasting a battery in the process =(

No problem mate, i do not have a multi meter to record measurements. The cells i were using were very new and had only had a couple of deep cycles before proper use. i fully understand why people record voltages etc but there are probably many average Joe's such as myself that buy the light online and try it on RCR's because the manufacturers blurb says so. The light is heavily marketed with the 550 lumen claim to help it stand out in the marketplace. I buy lights like this, put the correct batteries in according to the maker and run it. I do not have the time or patience to keep checking voltages etc. If it was a custom light then i could understand it. As i said, it may have been a one off with my light or the cells. I tried to use common sense with running it in bursts etc.

Regards,

Philip

Yes Warp. They are all pretty functional and easy to field strip. I own a G21 full frame. With DPM recoil system. What a nice and reliable life insurance it is! To be honest I own an H&K Mark 23 as well. It is so deadly accurate and not properly gifted

Said that. Please believe me. My eagletac xm-l as stock works smoothly with no mod with AW's 2900. This was not with other led assemblies. Please note that with this new release also the u.i. has been changed to some extent. Time to go to sleep here in Italy now. Read you with joy (not kidding or laughing at you) tomorrow. Best.

My friend received his brand new AW RCR 750 mAH Protected, and AW IMR 550 mAH batteries.
We tested his RRT-0 XM-L on all types of batteries.
On disposable CR123's, the the RRT-0 XM-L was dimmer @ some 260 lumens.
On rechargeables, there was NO difference in maximum brightness between the RCR and IMR chemistries.
We though we may as well use the RCR with the Protection Circuits from here onwards for safety...

Did you test the amperage draw at battery end with RCR?
AW does NOT endorse such RCR at more than 1.5A, so without any DMM reading use them at your own risk.

Unfortunately, I haven't gotten around to purchasing a Fluke digital multi-meter and learning how to use it.
However, I am keen on buying one soon, and learning how to use it too.
Will let everyone know if something goes wrong with AW RCR or IMR 16340's on the RRT-0 XM-L...
