IMR-9 in an E2X?

I was bored today and fitted a spare p60 into a E series head. I know that I didn't gain much since the output of the MN03 and the P60 are about the same.

This got me thinking has anyone tried putting a LF IMR-9 in an E2X host? I'm thinking that this should be noticeably brighter than the IMR-E2. You would lose about 5 minutes of runtime, but would gain 150 bulb lumens (75-90 SF lumens).

I guess what I am really asking is if the size of the actual p60 bulb the same as the IMR-9? From the pictures it doesn't have the tip like my P91 does.

So will it fit (with some modification to the springs)?
 
How did you get a P60 from Surefire to fit into a stock E series head. Is this the E1e, E2e, ect....?

Please explain and pictures would be cool too.:D

I came across the idea from a post from 05 and did a search and found this:

Its essentially the same with the P60. I just had to trim/bend both of the springs. I didn't use any washers though to focus it. So it's not quite focused yet, but I like it because it gives a brighter spill than the MN03. I might just keep it like this.




Oh and this is with my E2D.
 
Where did you purchase the McLux?

was it this item here?

Edit: I have LU60 collars that would accept the P60 xenon from Surefire easily. To fit the P60 LED drop-ins I grinded the circumference of the LU60 a bit. If the LED P60 doesn't fit the circumference of the LED reflector could be grinded a bit. Kramer5150 did this on his DX P60 Drop-in to fit inside a TOP xenon P60 flashlight. So, it is possible.

I have fitted P91 into E2D head 9 but the old version with aspheric, domed, lenze.

Havent seen the IMR lamps, but sounds do-able though.

Its possible to sand of the tip of the P91 to get it to fit....

Search E2+ or e2e P61 for old threads on this. :devil:

I have the IMR9 D26 and it is closer to the size of the LED P60 than the Xenon P60 from Surefire.

LOL....

I just realized the OP just used the lamp from the P60 not the whole P60 drop-in. For a minute there I thought he had figured out a way to make a Surefire E series P60 compatible..:confused:
 
You are using the only the bulb from your Xenon P60 drop-in.

I was refering to the P60 lamp/reflector. The P60 xenon reflector is thinner and shorter than a P60 LED drop-in. The D26 IMR9 is almost identical to the size of the LED P60 drop-in.

Now, I haven't noticed if the lamp within the IMR9 is the same size as the P60 lamp. I will have to wait till I get home to check.

Oh, cool then. Sounds like I got a new project coming up :twothumbs
 
I wonder if Lumens Factory would stick the IMR9 bulb on an E tower and save us all the hassle?
 
The lamp assembly inside my P60 from Surefire looks the same size as the lamp inside the D26 IMR 500 lumen.

I did a visual isnpection and size wise they look the same. If I hacked off the bezel It would be more accurate description, but I need it in P60 format.

It sounds like I will be doing that if I can't get LF to put to IMR-9 bulb in a E series format.
 
You guys just never can get enough output off those E Series, eh? ;)

No, we wouldn't make one because of the concerns on heat and tailcap issues.

Cheers,

The difference between the IMR-E2 and IMR-9 in output would be just barely enough to see with your eyes. if that....

Remember, the IMR-E2 has more than likely been optimized for use on the smaller IMR16340 cells, while the IMR-9 has been optimized for a broader range of cell sizes, including up to IMR18650s, with that in mind. Going from an IMR-E2, which runs brilliant white on a pair of IMR16340s, to an IMR-9, on the same cells, may not generate ANY noticeable difference in total output. Remember, lumen ratings are based on achieving a particular voltage at the bulb, and are not a given. Some configurations might be over those stated numbers on fresh cells, while some will never achieve them.

Thanks, I guess that makes sense then. Now to get the IMR-E2 :twothumbs
 
A question about tailcaps - how much current can a tape switch handle? The IMR-9-E bulb would be truly awesome for a ScoutLight setup - wicked bright, and very light. Also, it wouldn't have the sort of thermal issues present when running the bulb for anything but momentary use (which the tape switch is for). Also, the ScoutLight has the extra metal of the Picatinny mount (and the rail it's mounted to) to dissipate heat. Since my application is a paintball gun running liquid CO2, the more I use it, the colder the gun (read as: heat sink) gets...

Edit: I may have just been the first person here to seriously propose cryogenic liquid cooling for a flashlight just now. :D I've read about repurposing CPU heat sinks, custom heatpipes, even peltier junctions, but never cryogenic liquid air.
