Lumens Factory M series type bulb

[the fuzz]

Im getting abit confused b/c in the 1st page of this thread

Mark@LF

vbmenu_register("postmenu_1989403", true);

stated normasl configs

EO-M3T 7.2V 2.4A 450 Lumens

This was then questioned then afew post down from that page he states

"The EO-M3T is designed for M4 that uses 2x17670 Rechargeable batteries configuration or 3xCR123A configuration in M3T.

The lamp assemblies for M3T and M4 have the same LCL, and use the same type of base. The HO-M3T can also be used in M4 using two 17670 Rec. batteries for longer runtime."


But this new info hasnt been amended to Mark @LF initial lamp config 1st post

 

[mdocod]

and possibly the MN20 (but don't quote me on that last one)

BUAHAHAAHHA I quoted you !!!! you can't stop me!!! muahaahaahah!!!


ok ok..

I can confirm that an MN20 can be used with 17670s, it just won't be as white and bright and efficiant as a MN11/MN16/EO-M3T, but would have longer bulb life.

 

[defusion]

ok, lets make a list of things that should work (i'm not saying these are officially supported)

HO-M3
M3 with CR123's or 2x17500's
M3 + extender with 2x17670's
2x18650 leefbody + m3 bezel with 2x17670's or 2x18650's

EO-M3
M3 with CR123's or 2x17500's
M3 + extender with 2x17670's
2x18650 leefbody + m3 bezel with 2x17670's or 2x18650's

HO-M3T
M3T with CR123's or 2x17500's
M3T + extender with 2x17670's
M4 with 2x17670's
M6 on primaries

EO-M3T
M3T with CR123's
M4 with 2x17670's
2x18650 leefbody + kt4 on 2x17670's or 2x18650's
M6 on primaries

HO-M4A
M4 with primaries

thats most of them, I'm sure i left out some really obscure one's.

[edit in 6-22] inserting disclaimer:
LF lamps were originally tested for fitment and compatibility on only stock M3, M3T and M4 flashlights. As it stand now, there isn't a 100% guarantee that they will work on KT series turbo upgrade heads. It's theoretical.

 

[the fuzz]

thanks defusion and mdocod and the rest of your input looks like its the 17670 all the way



BTW

How do u bore out the tubes , do you need to take the tubes to a metal Smith ??

 

[Owen]

Well, I got my lamps yesterday as I was leaving for work.
The good news is that one of the HO-M3s gives one of the most perfect beams I've ever seen from an incan, with bright, perfectly even spill, not a single artifact, and a bright hotspot that fades into the spill, and a slight oval shape, not nearly as pronounced as similar SF, and most of the other LF offerings. Like a Wolf Eyes D26 on steroids, with great overall output assuming the current draw numbers are correct(I haven't checked). I love it.

The bad news is quite bad. The other HO-M3 doesn't have a perfect beam, matter of fact the hotspot is off-center and has a hole in it.
The HO-M3T got its keeper tube crushed and splintered at the top, along with the negative spring getting screwed up in shipping, but the springs are easily removed, and the one from my bogus HO-M3 fits it just fine. The globe is crooked, but I don't know whether that affects the beam or not. I never will know, since none of those things matter, as the pedestal that the globe is mounted on is too big, anyway, and doesn't fit in either my KT2 or KT4 turboheads.
Probably be a good idea for everyone to check each of their lamps rather than just sticking one in a spare carrier with the assumption that it'll fit in their lights--just tried the HO-M3T in a SC2 while typing this up, and had to use a screwdriver to pry it out after forcing it in.
I actually bought a M3T in anticipation of these bulbs, so I'm more than a little displeased.

 

[NYCblue]

I too was prepping the funds to purchase a turbohead for these bulbs. I guess I'll put the money on hold until (no pun intended) we can shed some more light on this.

 

[sixshooter_45]

I just received my EO-M3 7.2V 2.0A 380 Lumens, :twothumbs, from LF and it has a very nice round hot spot with excellent side spill and noticeably brighter than my M-10 LA in my SF M3-CB using two AW's 17500.

 

[Mark@LF]

Owen,

It seems like your lamps might be mishandled quite badly during shipping.

If one of your keeper tube is crushed to the point where the spring is messed up, then it has a high chance of moving the position of the bulbs in the package as well, resulting in bad focus.

About the fitting problem on the KT4, I would like to know a little more detail on this. As you know, I have checked every single one with my own hands.
Please sent me a PM on this issue.

Don't worry, I will get this solved and make you a happy customer at the end.


Thanks

Mark

 

[adamr999]

All four of the lamps I purchased fit in my SC2.

 

[mdocod]

Howdy Owen,

I'm curious about your experience there... Sounds like you have some major shipping damage or something there.. But the main thing that concerns me... is that the one M3T lamp is not fitting anywhere....

Just to recap: you have the following (you kinda threw it all in a flowing paragraph, I want to make sure I understand the cercumstance here)

1 perfect HO-M3
1 bent HO-M3
1 HO-M3T that does not fit into a spares carrier, a KT2 or KT4,

Now... yo mentioned that you ordered an M3T in anticipation of these lamps.... Has that arrived yet? if you get a chance please try to see if it fits there, so we can rule out all possibilities.

I'd love to see a picture of the offending M3T lamp next to one of your other MN SF lamps...

 

[defusion]

my plastic tube was cracked too, but didn't think too much of it, as it isn't exactly the sturdiest thing i've ever seen. it's just there to keep the foam protection in place IMO.

 

[Owen]

1 bent HO-M3

No bent HO-M3. It just doesn't focus like the other one.
I do have the M3T. That's what my KT4 is on.
A pic really won't show anything except a bent spring. I can do a pic later if you just want to see these lamps side by side with SureFire LAs.
I'm not having any luck with turbohead lamp assemblies right now. In the past week, I also fried two MN16s(the second one last night at work) on 2x18650 that I need to post a warning about

Since my package obviously suffered some damage during shipping, I'm going to avoid speculating about what might have caused "this and that" about my HO-M3T, and PM Mark to see about getting some replacement LAs.

 

[Manzerick]

Hey Folks,


Is there a bulb that will work with a M4 that uses 3 Pila 600s's?


If not, I can easily take out the A19 extenders to get more lumens

 

[mdocod]

I guess what I am confused about is, if you have a M3T, then why did you need a KT4 on it? Or was it an M3 upgraded to M3T with a KT4?

 

[adamr999]

I guess what I am confused about is, if you have a M3T, then why did you need a KT4 on it? Or was it an M3 upgraded to M3T with a KT4?

I believe the KT4 is the standard bezel on all of Surefire's turbo lights.

 

[mdocod]

well... As I understand it, the KT1, KT2, KT4, and Milleniom heads should all fit the same lamps, regardless.. I wasn't sure if there was a cosmetic difference of the KT4 compared to what would normally ship with a M3T/M4/M6... trying to figure out some stuff is all... Think it's a bum lamp.

 

[senna94]

This may have been covered already, but I was wondering how long it for most of you to get your lamps in the U.S. from Asia. I ordered mine yesterday and was just wondering about how long I will be waiting.

 

[Owen]

I wasn't sure if there was a cosmetic difference of the KT4 compared to what would normally ship with a M3T/M4/M6...

The KT4 is what ships on the M3T, M4, M6.

senna, usually ~10 days for me.

 

[tick398]

A question for those who have been using the EO-M3T in an M6 on primaries. How long of a runtime are you getting from this particular combination?

Also, would it be fair to say that the output of the EO-M3T would fall between the MN20 & MN21 in an M6?

Thanks!
