Re: New Ra Lights products (Bean #4)
Jeff, I count 23 different primary runtimes over on the Ra info thread. Maybe you should try reading the other peoples posts on this thread instead of staring "into the light". :nana:
Agreed! This reminds me of the immortal question that has been asked by humanity for millenia....."does anybody plan on doing a runtime test on any of the new Clickys, using a CR123 cell?"

I can do both, but not at the same time. I meant CR123 runtime tests, using the four new Clicky lights.....EDC-E, EDC-T, C-E and C-T. Who knows what Henry has incorporated in the electronics of these lights, being that the original Clickys had boo boos? 😱

Re: New Ra Lights products (Bean #4)
Both my lights 100CnWW and 170Cn have the latest electronics /Firmware. Although neither is technically one of the four latest products. I wouldn't expect the new firmware to change the runtime to the first drop though.
Damn the new naming conventions are confusing.

Re: New Ra Lights products (Bean #4)
Actually I have some primary Cr123 results I did a while ago and never published. After I did the run to first drop (which I published), I did some additional runs at lower levels on the same battery.
Results of SF primary (dtd 2014) using Ra170cn
120lm for 73min till first blink
then I turned it off and back on on my Med-high lvl
60lm for an additional 32min till blink down.
then I turned it off and back on on my primary lvl
15lm for an additional 105 min till blink down.
At that point I could have gone down to lower levels but I was sleepy and the battery read dead on my ZTS anyways.
Total runtime 3hr 30min.

Re: New Ra Lights products (4th Bean)
here i am... whew... i did not think that EDC T could make that long on a RCR battery. your test was even more that i espected.... the Ra's kick butt.

It's 10:00PM EST, do you know where your sappy is?

Re: New Ra Lights products (4th Bean)
I am just as surprised as you. But note that the start level was 85lm and not 100lm. My 140C lasted 67 mins. with the same battery, starting at 100lm.
Numerically speaking, my light's runtime increased 46.2% as a result of a 15% output reduction. I'll take it! It's non-linearity is in our favor.

Good to see you. I was about to file a Missing Person Report!

Re: New Ra Lights products (Bean #4)
My goal was to leave the light alone, and see how long it lasts before the once a second warning blinks start. I could have let the light run longer, because the AW cell is protected and will shut down at 2.5v anyway.
Recall that my cell ended up at 3.18v when I stopped the run. The cell had more life in it. But if one uses an unprotected R123 cell, you may want to heed Henry's warning and remove it when you see the once a second blink commencing.
Jeff
I welcome comments from all, concerning my belief that a runtime test of this type should be continuous from the start to the finish. This alone will demonstrate the efficiency of the light and the capability of the battery, as a team.

Re: New Ra Lights products (Bean #4)
A continuous runtime test like this isn't practical for me for two reasons.
1) I don't have a light meter so I am counting on the drop and the double blink as a warning that the light can no longer sustain that level.
2) Nobody would use the light in real life like that, the double blinking ever minute would drive them crazy. If I was out in the woods and the Ra indicates it can't no longer sustain max I would turn it off then back on to the lowest level I could practically use or change the battery. I would never just let it drop down one level at a time blinking away at me the whole time.
YMMV
Looks like you got an "XR", i don't see any reason that emitter couldn't have been a 140lm model, it should have been able to maintain a full hour easy.

Re: New Ra Lights products (4th Bean)
a very valid goal and your method was sound. this data expresses exactly the capability of these new Ra's and what can be expected of them. :twothumbs
me too.... i don't have a light meter so luxlover's run test is very worthwhile to me.
real world testing is just as important. it's good to know you can count on a Ra for well over an hour with very usable light from a half dead old battery. i don't have enough patience to do a real world test on one because i can't stop goofing around with the settings and i'm constantly switching the things on and off.

Re: New Ra Lights products (Bean #4)
1. My luxmeter has one purpose, to confirm that I saw a level drop, and not that I imagined it. I used to do a run without the meter in the old EDC days, without any slip-up. It is not a necessary tool.
2. I just realized that my light didn't do a double blink every minute after it dropped to 60lm. There is a reason for this. My light dropped one level eight times, and they occured less than a minute apart. If my light's runtime at 85lm was exceptionally long, then it really depleted the battery to a point where it couldn't sustain any level for an entire minute. Look at my times, with eight level drops in four minutes. Once the eighth drop occurred to 5.3lm, the battery was dead enough to trigger Henry's rechargeable battery protection circuit. If anybody wants to become nutso, just fixate on that once a second blink and you will be well on your way!
In conclusion, my mileage did vary from yours, and yours gives more miles per gallon than mine, because you drive your light in the real world style while I drive mine in the laboratory style. I see your point and fully agree with your method. This can only mean that running down a cell as I have, will yield the lowest runtime possible. (102 mins.) All other methods will yield greater runtimes. You taught me a lesson. :twothumbs

Tell Henry! Do you need his email address? I have it right here..... :nana:

Re: New Ra Lights products (4th Bean)

I approve of my method for the sole purpose of determining the shortest runtime capable of the light. Now that we all know that an EDC-T can run for 102mins. before the warning, we should use our lights as Dave has, conserving battery juice by using the lowest output that we need at the time. To quote Henry in the Introductions of his User's Guides, "You can maximize battery life by selecting the optimum amount of light for your task. Too much light wastes battery life while too little light makes it difficult to see."

Re: New Ra Lights products (Bean #4)
Jeff,
My millage was different because I was running a primary non-rechargeable cell. When using a rechargeable I experienced a similar drop sequence. Over the course of maybe 5-10 min the light went from full power down to minimum. Your Runtime data is useful because it lets RA users running a rechargeable know that as soon as they see the first drop in output (or the double blink) that they only have a few minutes of light remaining and they should lower the light to the lowest level usable to get to a safe place to and find and change batteries.
On a Primary battery after the first drop I got 6 more hrs of 9 lm light. (See my other tests in the info thread)

Re: New Ra Lights products (4th Bean)
Correction Jeff,
Now that we know your EDC-T can run 102min.
Folks, keep in mind the LED lottery is still alive and well. Henry's designs handle this different than any other LED light today. All his lights are designed to produce a specific amount of Lumens. This means all variability for Luminous efficiency and Vf ends up as runtime differences from unit to unit. Each Ra flashlight uses a different amount of current drain from the battery to produce the same amount of lumens. The only guarantee is that it will produce the max continuous for at least 1hr. (my 100ww won't even do that on the batteries I've tested) Expect a high degree of runtime variability from unit to unit as your tests show.
Its good to read the white paper that Henry wrote to better understand this concept.
Furthermore, I recommend everybody test there own light to see what its characteristics are on the battery and usage of your choice. Mine does not drop as fast on RCRs as Jeff's because I do see the double blink between drops. Also my battery read 3.24v upon removal, so it doesn't seem to drain them down as far either.

Re: New Ra Lights products (4th Bean)
Sent my RaClicky 170Cn to Henry last week for a software upgrade.
I've been meaning to do it for a while, but could not bear to be without it.
Anyway, got it back in the mail yesterday. Left my hands and returned in under 7 days....NICE!! :thumbsup:
No more flickering on low....LOVE IT EVEN MORE lovecpf

Re: New Ra Lights products (Bean #4)
Mine did. Ra Clicky Tactical (140). Arrived yesterday. Shipped with an Executive Manual and Quick Ref' Card though. Gotta say I like the clip in black.
I'm pretty sure I read in the contest notes that both the Ra Clicky 170s had the narrower beam pattern.
I did. I went for the Ra Clicky Tactical (with a flat tail cap this time).OK, who are the two lucky bananas who won the 170Cn Clickys in Henry's contest this morning? Come on, don't be shy!

i'm happy with the ones i have. are those 170's so rare that they have to be sold on a lottery?

I am happy with my two as well. No, they are not that rare anymore. Henry is selling two more in a contest this Sunday.
