TITAN PLUS

My new Titan Plus, serial number above A00800 arrived today. The LED and white bezel O-ring are centered. The beam tint is good -- not green, yellow, nor blue. Pocket clip edges feel somewhat sharp, as reported by others.

No surprises so far, and I await darkness.

Runtime test results are in.

:thanks: Thanks for creating the runtime graphs.

Would be good to see if high would come back on full strength if turned off after 5 minutes then turned back on after being off for about 1 minute.

I didn't do any duty cycle testing, but I did try it with lithium primary and it came back to the same ~60% output after resting a couple of minutes (it seems like the Titan Plus generates enough heat to trip the L92's PTC).

Many thanks for your work and Graphs!. I see a very good performance of lithium AAA in mediun level, instead the poor performance in high; but on the whole, Ni-Mh offers the better income.

It's a race car, Noctiluco; it's got a threshold. High for the Titan Plus is like being in the red. It's not good for a race car to be in the red too long.

It's actually not poor performance, it shut off due to the battery's thermal protection.

Hi Robin24K

I tested mine with an energizer lithium on high and its running continually for more than an hour now on a somewhat tapering output. Unfortunately, I don't have any equipment to test exact lumen count but I'll post back in as to how long it will run down to the minimum usable output. Maybe, you can redo your lithium run.

Run completed at 2 hour and 53 minutes with a declining output from high and simply switched off with about 8-10 lumens. Resting the battery for 5 minutes didn't make any difference as it will only turn on and switch off in less than a minute. Overall, I'm happy with the runtime. :thumbsup:

Did you measure the voltage in the battery ipon completion of the test. Just curious how much was left.

Now that you mentioned it, it says 1.38 on my crap tester and it actually works on a Lumintop tool AAA. I will put it back in on the Titan plus to see if there's still some juice left to run it.

Thanks. Seems kind of high. Probably get a more accurate reading with a conventional DMM on battery directly.

It only run for 11 minutes on low and now the battery reads .70 on my DMM.

That sounds more realistic. Thanks for doing this test for us.

Picked up two last night. Gave one to a friend and playing with the second. A few initial observations. White o-ring - acceptable to me on both ( s/n 908 and 1982) head turns easily and fairly smooth. To me it's heavy for a keychain but fine for a lanyard or pocket carry. The 900 mA Eneloop Pro was a nice touch as the Titan A came with a Surefire labeled 750 mA cell and I expected the same. So far the only thing I don't like is the type style used for the name. Now to live with it for a few weeks to see if it becomes my go to light

I just ran it a third time with the same result. What's the expiration on your L92? Mine are 03-2026, which is the latest one that says "9x longer lasting".

EDIT: Actually, not quite...I thought it was going to shut off like the previous runs, but it just picked up to ~8% output. Did yours maintain about 25 lumens for most of the runtime?

EDIT2: It's back up to 20% now. I think that with each "ripple" in the runtime chart, output resets to however much the battery can handle. :thinking:

The expiry of the one I used is 12-2034. Majority of the runtime up to 2 hours is a bit higher than medium. The High is less than 30 minutes then dropping to between medium and high.

I guess you have even newer ones, which has a 20-year shelf life? Just finished the test, here's the updated chart:

How hot did the light get?
