😊 thanks in advance for you awesome work.
 
Re: Malkoff Runtime Graphs - Ongoing Adventure

I don't know why I didn't do this earlier...

ok, I just checked voltage on 2x eneloop fresh off the charger. 1.45vea=2.9v

So 2.9v:
High mode is approx 155lm and 0.325A current draw. so that is 325ma

Low mode is approx 7lm and 0.019A current draw. so this is 19ma

now for the real testing.... stay tuned. Going to try high mode first and see how long it goes for. my guess is for a long while


I guess we should have clarified...My data is for the Neutral HD 18650. I am not sure which tint you have; hope it's Neutral because that is what i am testing.

Finally motivated myself to start working on some graphs. I have data moved to the notebook for several recent tests but have only made a few graphs. Will work on more later today.

Re: Malkoff Runtime Graphs - Ongoing Adventure

Your work and effort you put int theese test has helped many of us. My thanks again. Also I noticed in you test going back awhile that you were getting much higher output from your M60’s then Gene had them listed at. 400-430 range which is what he is saying he has bumped them up to now. That’s great work
 
@thermal guy: HD 18650 neutral 2x eneloop pro in high mode is still trucking along after 12 hours. It is only at approx 5 lumen but it's still going. I imagine it will still run for quite some time, if not another 12 hours.

@ETC: yes, Malkoff Nichia are not very efficient. I guess i will have to test M361N and M361 for comparison.

Luckily I do not own my lights for runtime and i do not use my lights for hours on end; so this does not bother me at all.

Wow! I never would of believed this would work with 2XAA will you be putting all this info in to chart form when the test are complete? And agin I/we appreciate all your hard work
 
No graph form...just going to torture you with subtle details/info...HAHAHA

I already have a graph that will look similar to this one. Let me think of what it is so you have an idea. I will tell you that within an hours time, It dropped down to 30 lumen I think...guess we will have to wait for the graph.

I am not sure i am willing to run this test in low mode though, that could possibly run for a few days.

Basically with this setup, the graph will show a huge drop shortly after the start of the test (within the 1st hour)then level out for the remainder of the run. So it would be like driving down the backside of a mountain and leveling off in kansas...maybe wyoming would be better since the I-80 actually does exactly how this graph will look.

just to be clear, i will make a graph for this test. :p
 
hound dog 18650 with 2x AA?!

woooow!!

Why did not I think of this before? lol


It's great to know that this is possible.


I would particularly use 3xAA because the flashlight supports up to 6v.
with 3AA the runtime should be very interesting ... :)
 
possible yes, fit your needs, IDK. in an emergency situation, definitely.

with many playing with different options for power, I will eventually have to see how much voltage is required to run all these modules. there are definitely options that do not agree with the voltage ratings but work

Yep I have been looking for my ultimate survival light for a while and might just of found it. You get full power plus a great low with 18650/123. And the ability to use 2XAA in a pinch. I’m trying just regular Duracell alkalines now. If I get good results with them I will be very impressed
 
thermal guy


certainly the lantern hound dog 18650 is one of my favorites.
I had never thought to use AA batteries with this flashlight. this possibility opens new horizons and so I agree with you that this model is one of the most versatile.
It is not without reason that I have two of them. lol


for me the lantern hd18650 enters the hall of fame along with the dropin nichia m61lll :)

Saw that woods walker put together something like this with a G3. Love the idea of having multiple batter options.Now I have a light that will reach out there and if need be run for days on readily available cells.
 
SF G3 with a variety of low power dropins is a fantastic emergency host.

I have recently added several to my collection, especially for vehicle kits.
 
impressive.
I would suggest a test with 3AA but I believe it would be time consuming.


knowing that it is possible to use 2AA and get a runtine of more than 15 hours is enough to know the potential of this flashlight.
 
I agree that the numbers do not sound bright, but as you have seen; it puts out more light than one would imagine. We are between 3-4lm...more on the lower side of 3 but I could easily use the light still. Reminds me of the Super. maybe not a ton of lumens in different variations but it still holds its own
