Hi all from a longtime lurker. :wave:

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.

Re: Wan't to post some runtime graphs

Hi and welcome to CPF ! :wave:

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 :D

Re: Wan't to post some runtime graphs

:welcome:

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. :grin2:

Re: Want to post some runtime graphs

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.

Re: Want to post some runtime graphs

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

6P-P60.jpg


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.

Re: Want to post some runtime graphs

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.

6P-P60L.jpg


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.

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

Re: Want to post some runtime graphs

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

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

Re: Want to post some runtime graphs

Hello BigWaffles --


Welcome to CandlePowerForums !


:welcome:



Thank you for your lovely Run-Time Graphs.


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

:thumbsup:


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.

:goodjob::thanks:

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/features/lightbox_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.

Re: Want to post some runtime graphs

Here is my second favorite light, the Surefire A2 with white LEDs. This graph is of the Incan & LEDs on Surefire Primaries.

A2-Incan.jpg


Some interesting regulation on the Incan. Mine cut off at appx. 45min after which the LEDs didn't last very long.

Re: Want to post some runtime graphs

And here is the same A2 on LED only with fresh Surefire primaries.

A2-LED.jpg


Again, I think Surefire rates their runtime until exhaustion. I hit 50% at 15.5hrs. I'm sure it would still be lit at 20hrs but not very usable.

Re: Want to post some runtime graphs

Here is the Inova Bolt 2A on Energizer Alkalines.

Bolt2A.jpg


This light and the Bolt 3A are my go to lights for around the house. I was a bit dissapointed in the 2A runtime, I was hoping for closer to 3hrs. I'll have to re-test it with different brand batteries. Has anybody had different experience with the runtime of this light?

This is a great light for working on computer equipment. The rubber grip makes it easy to hold in your mouth and the beam seems spot on for close work.

Some interesting jitters in the graph. Not sure what the driver circuit is doing but it doesn't seem noticable in the beam.

Re: Want to post some runtime graphs

And now to my favorite light, the Surefire E2L. This graph is of the High level with Surefire Primaries.

E2L-High.jpg


I purchased this light about 4 months ago and it has been my EDC ever since. The regulated runtime is every bit as advertised (6hrs) and it even ran an additional 90min after it dropped out. Very usable light for low speed trail navigation in the dark and general purpose.

Re: Want to post some runtime graphs

And here is the same E2L on Low with Surefire Primaries.

E2L-Low.jpg


This is why I EDC this light. Just over 63hrs regulated runtime of very usable light. Unfortunately, from the way the output fell after dropping out of regulation, I highly doubt this would make the claimed 100hrs runtime. If it did, I don't think you'd be able to see the light with your bare eyes.

Has anybody had a different experience with this light?

Re: Want to post some runtime graphs

Ok, onto the G3 series. Here is the G3L with the P60L LED on Surefire Primaries.

G3-P60L.jpg


A good general purpose light. Regulated runtime was spot on at just over 5.5hrs with an additional 2hrs of usable light after falling out of regulation.

Re: Want to post some runtime graphs

Here is the G3 with the P90 Incan on Surefire Primaries.

G3-P90.jpg


This light shows the same initial bounce as the 6P with a P60 Incan. Again, not sure if its something in the batteries or just the way Surefire Incans work.

Runtime was good, lasting appx. 70min to 50% with an additional 30min of usable light.

Re: Want to post some runtime graphs

Here is the G3 with the High Output P91 lamp.

G3-P91.jpg


I was a little disappointed with the runtime on this one. Surefire claims 20min and mine died at just over 14. I noticed that the batteries were VERY hot when this was run (probably due to the high drain). Would an aluminum 9P body dissapate the heat better and give longer runtime?

All in all, the additional 6 minutes isn't a big factor. I only use the P91 lamp when I need to scan a hillside; looking for the best way down or to find camp. It rarely gets used for more than a few minutes at a time.
