A Collection Of Runtime Graphs

BigWaffles · Feb 18, 2009

I ran into a little snag trying to upload the .xls files to Google Docs, it seems that there is a 1Mb file size limit on spreadsheets. The raw data in .xls format is exceeding this limit in most of my files.

What I'll do is upload the raw data in .csv format for each graph. You can open a .csv file directly with Excel and then just save it as a .xls. It will take longer this way but you will have all the raw data. This data includes date, time and Lux for the entire run for each flashlight.

The good thing is that Google Docs doesn't limit the number of files I can upload.

I'll get started on uploading the files and then group them in one post when finished. If I have time I'll also upload all the graphs in .jpg format so people can download the full sized graph files for viewing.

I found a better solution than Google Docs. It's called Google Sites. It allows you to make a web site and just post the complete files for download. The nice thing about it is that it just hosts the file, it doesn't make changes/limitations to it. You can go here to see what I've got uploaded so far:

I'll be uploading the complete .xls files as I get to them so keep checking back; these files will contain the raw data and the graphs. Once I get all the excel files posted I'll start posting the .jpg graphs for those who don't want all the raw data. Later.

22hornet,

Ok, this should be better for regulation. Here is the 6D Maglite with the Malkoff drop-in, I stopped this after 27 hours as it had entered Moon-mode and probably would have continued running for the next couple of weeks. Once in moon-mode the 4D and 6D were almost identical (you can't quite see it but both lights run to the end of the graph).

I'm glad I reran the Malkoff on the 6D Maglite, those extra 2 batteries made a huge difference; 13hrs of very flat runtime before dropping below 13,000Lux.:huh: It would seem that the Malkoffs perform best at or near their max voltage.

when you get your tenergy 12000 d's, run 4 of them and you'll see a runtime graph not far off from the 6d. they wont sag under the voltage. just make sure to break in the d's with a few runs before you run an "official" test. once you go rechargeable, you'll never go back.

What's the voltage on these fully charged? From my reading, most rechargables have a higher voltage than regular batteries. Won't be a problem in the 4D but might overload the Malkoff if I were to try it in the 6D.:poof::eek: Thanks.

Actually NiCd and NiMh cells fully charged have lower voltage than regular cells, but cab operate at higher discharge rates, holding their voltage for a longer period of time than regular cells, ie primary cells. The high discharge rate of NiMh cells, for example, will give longer runtimes at higher output in the Malkoff's. Six NiMh's in a 6D will read about 8.4 volts fully charged, maybe a little more, and rested will read about 8 volts.

So this week at work I got notified of an upcoming deployment I'm going on. Part of the equipment they issued me is a Fulton Anglehead flashlight. I was given the newer LED version so I thought I'd do a runtime on it just for kicks. Here is the Fulton Anglehead LED on Energizer alkaline batteries.

:sick2: I think I'll take one of my Malkoffs instead.

BigWaffles · Mar 1, 2009

Just out of curiosity I re-ran the runtime on the Fulton Anglehead with the incan that came in the tailcap. This is on Energizer alkalines.

It's hard to believe that the military got by on these for as long as they have. We've come a long way...

BigWaffles · Mar 1, 2009

So I noticed that I didn't have a 2D Maglite in my collection so I picked up an LED version (old style). Here is the 2D Maglite with the Mag LED on Energizer alkalines.

Not bad runtime for a 2D cell light.

C.P.T.

BigWaffles · Mar 1, 2009

Here is the same 2D Maglite with the Niteize 1W drop-in. This is running on Energizer alkalines.

Not a huge difference over the stock Mag LED.

BigWaffles · Mar 1, 2009

And here is the 2D Maglite with the stock incan (1K6) on Energizer alkalines.

BigWaffles · Mar 1, 2009

For comparison, here is a compilation showing all three tests for the 2D Maglite.

BigWaffles · Mar 1, 2009

I received my 'D' cell NiMHs this morning and am running them through a couple of charge/discharge cycles to get them ready. When finished I'll re-run the 4D and 6D Maglites with the Malkoff drop-in on NiMHs and post the results.

Also, when they're back in stock I plan on getting a Malkoff Drop-in for the 2-3D Mags. When I get one I'll run it in the 2D and 3D Mags on alkalines and NiMHs and post the results.

Back to the lab...:naughty:

Hello Big_Waffles --

Thank you for these wonderful graphs !

:goodjob::thanks:

Can you please tell us . . . .

Which type of incand. bulb was used in each ?

PR-2 ? KPR-2 ? any specifics would be handy.

(yes, i know it'll be tiny -- get yer' magnifier out) :eek:

Good Luck in your new deployment.

Stay safe.

Burgess,

Here are the Incans I used (hope I got the right number off the base)

Fulton Anglehead - PR6
Mag 2D - 1K6
Mag 3D - 1G4
Mag 4D - 1C7
Mag 6D - 1A6

These are the stock bulbs that came with the lights. I updated the posts I could find (I don't think I posted the 4D & 6D Incans). Hope that helps.

I finally got my 9P. Here is the runtime of the 9P with the Malkoff M60 on Surefire primaries.

Nice 2.5hrs regulated.

C.P.T.

BigWaffles · Mar 1, 2009

Here is a compilation showing the Malkoff M60 in the 6P and the 9P. Both tests were run on Surefire primaries.

That extra battery gives it an extra hour of regulated runtime. The 9P just kept going at the end and didn't want to die.

C.P.T.

Bullzeyebill · Mar 1, 2009

That comparison of M60 with 6P and 8P just throws me. I did not realize the extra cell with Gene's circuit would made such a difference in runtime, and I would have expected some higher output with 3 cells. Maybe it gets hotter with three cells dropping output and at the same time extending runtime. Would be interesting to see the M60 runtime with the module wrapped tightly with aluminum foil.

Any chance of seeing a Rebel 2D Mag on those great graphs?
