Lumens Factory IMR-9 Arrived! Beamshots, Current Draw, Median Luminosity, and Runtime

[RobertM]

It was quite a pleasant surprise to come home from work and see that my new IMR-9 had arrived from LF.

I just fired this bad boy up in my SF 6PL with two AW IMR16340 cells. Wow, it is very bright!

It has a beautiful, perfectly round, super bright, huge hotspot! This is awesome.

Time to go play some more. Beamshots to come tonight...stay tuned. :devil:

UPDATE: Current Draw
I just measured the current draw to be 2.3A on 2xIMR16340 cells on the Fluke 87 DMM.

UPDATE: Beamshots

Unfortunately, I couldn't take any outdoor beamshots since it's snowing, but here are some indoor beamshots. All camera setting were manually locked and remained constant for all the photographs.











UPDATE: Median Luminosity
Using Photoshop, I check the histogram for each photograph and thought that you guys might like to see the median luminosity value for each light/beamshot for comparison sake.

Median Luminosity:
12 - SF P60
19 - SF P90
37 - LF IMR-9
41 - SF MN20
77 - SF MN21

UPDATE: Runtime

I do not have any special equipment for doing any runtime tests, so I can't post graphs or anything cool like that. I simply turned the light on, and timed it until I saw it dim considerable. This bezel of my SureFire 6PL gets really quite hot after running for 5 min. continuously. After 5 min., I let the light cool for 7.5 minutes, then ran it for an additional 5 minutes. After letting it cool for 2.5 minutes, it ran for 2 more minutes until I saw it dim significantly and I terminated the test after 3 minutes.

In total: 12 minutes of runtime. After 13 minutes, I immediately removed the 2 IMR16340 cells from the light and found that they actually had different voltages: one was 2.56v and the other 2.82v. After letting the cells rest for ~5 minutes, they read 2.84v and 3.03v. Does anyone know why this would be? Anything to be concerned about?

Re: LumensFactory IMR-9 Arrived!

Do you have EO-9 to campare with , and/or P91 ?
can't wait to get my hands in my IMR...

Unfortunately, I do not have either of those. I plan to compare it to a SF P60, SF P90, SF MN20, and SF MN21.

So far, it looks to be about equal to the SF MN20, but it has a much whiter, rounder beam. The MN20 has a tighter (smaller), but more football shaped hotspot.

Re: Lumens Factory IMR-9 Arrived!

Nice , so it appears to outcome the P91 as the MN20 has 250 SF lumens...that would be great...

Re: Lumens Factory IMR-9 Arrived!

Just added current draw to the original post... 2.3A!

That's very low!
What's your reading with the SF P90?

I can't stop grinning when I play with this lamp

Paul5M,
I just tested my P90 on the Fluke... 1.15A

Re: Lumens Factory IMR-9 Arrived! Beamshots Included

I got my IMR-9 today, as well as the version for the E2e. Certainly noticeably brighter than the SF P60 that was in my SF 6P before. I guess I was expecting a bit more, but it's 500 bulb lumens, not 500 out the front SF lumens.

Can anyone guess the out the front lumens? 300-350 maybe?

I don't know what it's "out the front" lumens would be, but I'd say that it's ~250 "SureFire lumens." :thumbsup:

If only I had a light meter :laughing:

Hi RobertM,

Glad you liked the bulb. :laughing:

Tell you what, 2.3A is not the design current.
Go use 2 x IMR-18650 and try again.

Hopefully, AW will make some 17500 or 18500 so you can use a 9P or something and get the best out of the lamp.

Cheers,

Mark

Hi Mark,

Unfortunately, I do not have any IMR18650's yet nor do I have a 2x18650 host. Would you be able to tell me how far off my 2xIMR16340 setup is from what it's designed to run at?

Thanks,
Robert

The beamshot from the MN21 produced a spot in my vision and caused me to look away from the computer screen:naughty:

...nor do I have a 2x18650 host.

Hopefully, Lighthound still carries the Leef C-C or Fivemega 2x18650 tubes and has them in stock.

Last year, I was hoping to get myself started on experimenting the IMR setups. Your last three beamshot pics are really very seriously tempting.

Fivemega sells his 2x18650 tube with a 1794 lamp, which proves to be very impressive in its own light/right. The light itself is slim and handy. The beams it shoots out is floody and superb for general household use. My only complaint is that since the bezel is small and the actual lamp is very close to the pyrex glass, the front of the lamp gets hot very quickly. While it is cool and YouTube-worthy and all to have a flashlight that can ignite newspaper with its beam, I think of it more as a safety hazard during use.

Thanks again for posting the beam shots. Do you get the bulbs directly from LF or where would be a nice place to purchase them?

With Aloha,

Clarence

I got the IMR-9 today, and went out tonight with my L2D to compare. My first bright Incan and wow. I have the same set-up RobertM has, and his beam shots look like what I am seeing with this light. The LED is like having the moon, and the IMR-9 is like the sun about an hour or two before sunset. Very impressive.

But what's this mean: ' Tell you what, 2.3A is not the design current.'? The LF site says the IMR-9 is for 2 x IMR16340 or 2 x IMR18650. Are the IMR16340s really not a powerful enough battery for the IMR-9? What will the effects be of not running the IMR-9 at the designed current?

Re: Lumens Factory IMR-9 Arrived! Beamshots Included

I got two IMR-9s few days ago. These are my first incan modules and i like em.

I tested both of them with PSU and got these numbers out of it.

7.4V ~2.30A
8.0V ~2.40A
8.4V ~2.46A

Clarence,
I purchase my LF lamps directly from Lumensfactory.com, and occasionally from lighthound.com if I have other things to buy as well (i.e. IMR cells, etc.).

Jesseri, I find it interesting that you too measured 2.3A. Thanks for posting your findings. So it would seem that my IMR16340 cells are actually not sagging beyond 3.7v each?

Robert

Re: Lumens Factory IMR-9 Arrived! Beamshots Included

Yep, it seems so.

Those numbers are taken from PSU's integrated volt-/ammeter and i somewhat trust it. I even took my cheap DMM out from the storage (trash bin ) and measured current from two freshly out from the charger IMR16340 cells and IMR-9.

There it was, 2.33A. As i don't take the numbers from my DMM with a grain of salt, I hooked the other IMR-9 to PSU and upped the voltage to 7.4V (2.31A from its integrated ammeter) and then compared both beams. They appeared quite identical.

Now we know why Mark@LF refuses to publish the current specs of his so-called "IMR" lamps
