When You Want Long Runtime...

[etc]

I did the same thing with with a 3D mag. I think the rated runtime is about 100 hours.

My longest running mods take the form of a 3D Mag with a 3 mode AMC7135 based driver. I use 3 D AccuEvolution 10,000 mAh LSD NiMH cells to power the mods. I have made 4 of these to date and they work well. Here are the runtime specs. 140 mA on low mode. This gives you about 50 lumens with a 70+ hour runtime. 1000 mA on medium. This gives you about 300 lumens with a 10+ hour runtime. 2800 mA on high mode. This gives you about 700 lumens with a 3.5+ hour runtime.

Happy mods!

The 10MM Nite-Ize drop-in will run for a couple of weeks :candle:. A few guys tried doing runtime tests on it one time, but gave up after the first couple of days. :twothumbs

I thought there was a test done by BigWaffles and it indicated about 90-100 hours. pretty good but not really as good as I hoped. 100 hours = 4 days. I don't think its a few weeks. Do you have a link where it ran for weeks? Unless it drops into the way sub 1-lumen moonlight level.

I put a floody reflector in it and it made it much nicer.

You're right, it did run for 90+ hours (IIRC that was a 3D mag). So on 4D it will run a little longer, on 2D it will run a little less.

I don't like runtime given in days because I can't think of anyone who uses a flashlight for days on-end. Usually you just use it between dusk and going to sleep. So if you ran the nite-ize 10mm PR dropin in a 3D mag for 6.24 hours per night, it really would last two weeks.

freeplay kito(crank flashlight).


go on forever or til my arms fall off. whichever comes first.

or

how about a fully mirrored room filled with a hundred solar powered flashlights. you'll look like george hamilton in a week.

Yeah, I read the one BW did, but I think there was another I read 2 years back (:thinking:), where he basically gave up on it, and stated it in the thread, but it may have been where it hit the "bottom" and he figured it would run at that lowest of low's (although useable) for who knows how long...1 lumen ain't much, but when all the batteries are gone and it's pitch black in a basement or attic...

I wonder if you soldered a resistor to the bottom or inside of it, if you could double the runtime at half the lumen out-put???

Ditto...unless it's hard to get an accurate reading, I can plan how long to use my light each night (ration it if batteries are low and the whole city is gone and everythnig locked up or already stolen), and secure myself by saying "If I limit it's use to 4 hours a day, it will last me approx. 4 weeks", etc.

anybody in the path of the hurricane going up the east coast now? Might get to test some of these theories.

Where does one get good alternate reflectors for mags these days BTW?

I don't recall exactly but it may have been lighthound. One of the major vendors here, anyway.

My Novatac 120P on low (.08 lumens) runs approximately 750 hours on a single CR123. If I spend 30 minutes in very low light (moon), the .08 setting appears bright enough to navigate well.

My TNC light also uses a CR123 or RCR123 and runs for 6000 hours on it's lowest level and 600 on the second to lowest. Yes, 6000 hours. At 8 hours per night, that's two years of run off a single battery. I have 100 lithium batteries in storage, rotating in new ones as I draw from the supply. I guess I'm all set for the next 200 years or so. :)

x2... this is a really nice general-purpose setup. Its around 50L IIRC. You can also lego a 1x18650 extension, and run it regulated off 2x18650.

Yeah, I do both. M60LL is a surprisingly versatile module that plays well with any configuration.
I have a large supply of unprotected 18650 cells, I am confident M60LL and 18650s can get me through any power outage. Just that lite alone can generate 1000+ hours of runtime with 18650s I pulled from laptop battery packs.
When that's over, I can go to primaries, which I have hundreds of...
When primaries are gone, I can go to Lihium AAs.
When that is gone, I can use Alkalines.
When Alks are gone, I can use Carbon Zinc heavy duty.

Plus the tint is very nice and the lumens are not a joke. Really a step up above something like Infinity. Mine is blue and dim (of course).
I don't think I can deal with less than 40 lumens in the primary EDC lite. So for me, this is as good as it gets.

About the old MiniMag with SMJLED module, I hear the runtime was supposed to be close to 40 hours?

How does it compare to the "Low" runtime in the new Minimag with Rebel and Multi-modes? I think the high is probably 50 lumens. If the runtime is about the same, it's nice, since you can also use the high mode.
