A Collection Of Runtime Graphs

[BigWaffles]

Hi all from a longtime lurker.

I've finally decided to take the plunge and try to give back some info to this site after soaking up so much from the posts.

I recently constructed a light box (courtesy of flashlightreviews.com) and just finished runtime graphs on most of my lights. I would like to post the data (.xls format) and am not sure how best to proceed. I have a bunch of 1.5Mb spreadsheets that include the raw LUX data from a datalogging meter and graphs. What I need to know is where/how to post them.

Would these be posted in the Reviews forum or General? Also, what is the best way to attach/link to a spreadsheet?

Thanks in advance for any advice and keep the information flowing.

Hi and welcome to CPF !

Cool project, runtimes are always welcome here.

As to your questions:

Attachments are not possible on CPF, you'll have to host the files elsewhere and link them here.

You can post a pic of a table or of runtime graphs, but I doubt that the software can display spreadsheets made of raw data.

I think showing the result of the data is better anyway, since a lot of raw numbers are difficult to grasp. For me, at least

Plot in xls, do screen capture, paste in photo program, crop, save as png, host on photobucket free.

That's my method.

However, I'd appreciate the raw data too, if it works somehow.

Mods, feel free to relocate this thread if necessary. Thanks.

Ok, here's how I'll do it: I'll post each graph seperately with explanations and questions I have about the results. Also, I'll offer the raw data to anybody who requests it in .xls or .txt format.

First a little explanation about the graphs:

1. All graph values are in LUX on the vertical and Minutes on the horizontal.
2. The graphs start with the first usable reading and run untill 500Lux or 50%, whichever is lower. I chose 500Lux as a low for the graphs as this is the minimum amount of light I consider usable for most applications.
3. These are standard Excel graphs pasted into paint and then saved as .jpg files.

Ok, as soon as I figure out how to post pics I'll get started.

I'll start out with the venerable Surefire 6P with the standard P60 module.



Not sure about the initial bounce (batteries?) but it made over 1 hour until 50% on Surefire primaries.

I'll post more as I get them uploaded.

I'll post one more for tonight and give the Mods time to approve them.

Here is the Surefire 6PL with the P60L module on Surefire primaries.



The 2008 Surefire catalog states 11hrs runtime on this light, but I think that's until exhaustion. As you can see, I got almost 4hrs of regulated runtime and then shut it off at just over 5.5hrs at 500Lux. It might still have been lit at 11hrs but I don't think I'd want to try to navigate with it.

Has anybody measured longer than 4hrs regulated runtime on one of these?

Later.

Let me know if you want data in the raw .txt dumps from the datalogger or in the .xls format (1.5Mb each). I have runtime graphs on the following and can e-mail what you want.

6P-P60
6P-P60L
A2-Incan
A2-LED
Bolt 2A
Bolt 3A
E2L - High
E2L - Low
G3-P60L
G3-P90
G3-P91
Mag 3D Mag LED
Mini-Mag - Incan
Mini-Mag – Mag LED
Mini-Mag - Niteize 3LED

The graphs look good, BigWaffles. Thanks for posting them.

I will be interested to see the E2L and Bolt runtime graphs.

Hello BigWaffles --


Welcome to CandlePowerForums !






Thank you for your lovely Run-Time Graphs.


That's something we can never get enough of, here at CPF.




I, for one, would love to see all 3 of your Mini-Maglite graphs.


For the incand. Mini-Mag, can you tell us the color-band of the Lamp ?
That's how to identify "which" type of Bulb you have.
Believe it goes: Pink (original), Green (next), and Black (newest version)



Can you tell us, specifically, what device you employ
to measure & capture the Run-Time data ?


Thank you for your time and efforts.

The Mini-Mag was a Black Band. I'll reiterate this on the graph when I post it.

All measurements were taken with an Extech Datalogging Light Meter, Model 401036. I connected it to a laptop to log the data for the longer runs.

I made a light box constructed with instructions found on FlashlightReviews.com -http://www.flashlightreviews.com/fea...box_output.htm

The only difference in the light box was that I put my sensor on the side with the baffle and my lights in the end.

Hope this helps.

bigwaffles,

thanks for the effort and result..

Now you need a website to host them...

Bigwaffles,

A big thank you for the excellent work. Runtime graphs are gold around here!

Excellent data Thanks for your effort

I did not look at this thread for a long time due to the title. You may want to change the title now that you are beyond "wanting to post runtime graphs" to "a collection of runtime graphs" or some such.

To do this - edit the first post in the thread and select the "advanced" feature to get at the title. It is under your control there.

See Gene's website re specs for the M60LL. It will answer questions about use in a G2.
