Looked dead flat. Then dead off! I’m always very careful when out and about with rechargeable batteries. There is absolutely no warning when she’s dead she’s dead.

Hi INFRNL!
I very much appreciate the runtime graphs! Apologize if this question is already answered somewhere but: do you know what's the runtime difference is between the M61T you measured and the new one with higher output? Is it otherwise possible to do a test?

I have the new M61T love it. Malkoff site list 1.5 hours on 2X123. Not sure what the old one was rated at. I normally run a 18650 in mine so not sure I can help much but, if memory serves the newer M61T was just slightly less runtime. Not much though

I'm sorry, I do not own any of the latest lights/modules. I think I did a test on the new M61 vs the previous gen IIRC. Not sure if I ever got the data posted (thought I did). From my limited experience, the new lights/modules run hotter and have a bit less runtime due to the increase in output

Have you had a chance to test the M61LL; apparently rated for 100lm x 10hrs.

I soooo wish I could read all them charts. On my iPhone there one big blur.

Wonderful, thank you. That's exactly what I was hoping for.
I wonder what the brightness/runtime is with a 18650?

I can read them on my phone but i have to select desktop site.
At one time i redid many graphs so they would show properly on a phone. Not sure if something changed but lately they first appear small
Sorry buddy, whish i would have been able to make everything better and easier
If everyone would get away from the iPhones, it's easy on an Android:kiss:

Okay guys, still alive as many know. I know it's been somewhere around 10mos since we had any progress and i apologize. Don't get your hopes up, but i might start trying to do a little more testing. I was working on cleaning out my message box and came across a message about a run I was going to provide.
I have 2 sd cards that i put test data on...so I took a look and am trying to make sense of it and i think I got it somewhat figured out. I just went and looked and I now know where I left off
I have a bunch more data from when I was comparing Moderns M61 425 to my M61 325...for those of you that don't know. 325 is the previous gen module and 425 is the current gen which started around the end of QTR 1 2018. Well I have the rest of the tests done (which were done last yr) but i need to transfer data from the SD card to my notebook, then make graphs.
Lastly, during this time or just after I got a request that many wanted to know how an LL module would do on 3x primaries. as well, test was completed last yr. Sorry it has taken so long and you probably don't care so much anymore or have given up on me, LOL. I have the data transferred to my notebook and just need to find a base graph to make the graph for it. It has been so long that my groove has been covered by new debris. This graph may not match that of the previous graphs but it should be close. I will finally post it up for you, but it will take me a minute to remember the coding for the links in the first post....
Be back shortly

It will take me some time to get the rest of the data for the m61 tests as there are several. I will try to get those done before I even think about any new tests
It appears that I have 7 tests i need to make graphs for. 6 are for the current m61 and 1 from previous gen. I will try to get these posted by sometime this weekend

Thank you for doing more testing of the M61LL series. Looks like there is a bump in output and a ~2hr increase in runtime with the 3 cell configuration. Meanwhile it looks like the 1xCR123 does not run regulated?
I'm not sure if you've gotten a chance, but have you tried M61LL with a 18650 battery? I'm curious how the extra capacity / lower voltage will effect output and runtime.

The M61 series is not really designed to run off of a single primary. They will run in direct drive below 3.4v, so it won't be regulated.
I did not have any current plans to run this module on an 18650. but going off of the test results; I imagine it will run for quite a while with output somewhere between the MD1/MD2 primary results. I can see about running a test.

So the LL will give you more output and several more hours of runtime! That’s a win win. I like that

The only last gen vs current gen test I was able to do last yr was between the M61. I believe I posted some results but I do know I have 7 more tests to go through and post for the m61 prev/current. This might be enough to help you with the T but not 100% certain

It is looking like things went south around the time I finished testing the current M61. I have 2 cell comparison graph but never linked the individual tests. I have most every configuration of the current M61 425. some tests I have data for which should mean I have graphs, but I have like 6 other tests in which I need to complete my work process for. I also need to see what tests for the previous gen M61 325 need to be done for comparison. I have 1 test in which i need to complete my work for to produce a graph.
It will eventually come back to me and i will get back on track

Hi,
When you test the lights, how hot do they get? And does the heat travel down the light body enough to bother you? Or does it stay at the head?
The reason I'm asking is because I just tried holding my Convoy C8+ on max output. After only a few minutes, the whole light became unbearably hot. The output didn't drop, to my eyes at least, which is a good thing. However, the heat! The Convoy C8+ is the size of the M61HOT MD2, except with a larger head diameter.
Does this happen to Malkoff, Elzetta, HDS, Texas Lumens, Oveready, etc.?

During my testing the heads do get really hot but I try to test during the colder season when my garage is really cold. sometimes i test when ambient temps are in the 70's but I have a fan that sucks air across the lights to help control temps.
some of the higher output lights like the wcv6, hound dogs can get really toasty and too hot to hold if there is not proper airflow. as long as the Malkoffs have good airflow, they shouldn't ever get too hot to hold, but they are capable of getting to over 140deg.
during my tests only the heads get hot and just at the top of the body but the head and just under the head get the hottest during my tests. If i didn't use a fan, they would get too hot to hold but my testing is also face down with no air to the lens part of the head.
