KT2-BK TurboHead Conversion Kit question

[Nite]

LF EO-M3T (9V, 450 Lumens) Extreme High Output Lamp Assembly

will that fit into this KT2-BK TurboHead Conversion Kit For 9-Volt Flashlights (KT2-BK)??:shrug:

Is this a "M"series head?:candle:

i think this is the right place for this question

the above Head uses the N2 Lamp....are there some Lumens factory equivalents.
what else can this head be used for?

The KT1/KT2 Turbo head will not take the LF EO-M3T lamp assembly. It's a C-series turbohead which takes a tower-type lamp or LED. The reflector is built-in to the head, and the tower is inserted into the back of the reflector. FM's bi-pin adaptor will work in the head.

thanks

The KT2 TurboHead Kit comes with the MN15 Lamp Assembly (previously it came with the N2 Lamp Assembly). The Kit comes with an adapter collar to attach the KT-TurboHead to standard bodies such as C3, G3, 9P.
There are no adapter collars to attach it to the E-Series or Millennium Series threads (of the M3, M4, M6).

The "M-Series" TurboHead is called the Millennium TurboHead. It is shock isolated and requires no adapter to attach to the Millennium Series threads.

The KT2 TurboHead...
There are no adapter collars to attach it to the E-Series...

Actually, there are, but not from Surefire. Both TnC and Vital Gear make E2C adapters which will work with the KT1/KT2 TH heads, allowing them to be used on E-series tubes.

Actually the KT1/KT2 Turbo head will take the LF EO-M3T lamp assembly. You can then fire it up with any body that takes 3 X CR123 or 2 X Lithium-Ion rechargeables.

Ah well - my interest doesn't extend much beyond SureFire products does it!
Of course these aftermarket adapters require the SureFire adapter as well right? I was considering only one-piece solutions.

You're right. I was thinking of the shorter HO and EO-M3s.

Correct. They require the female C-Series threading.

will this fit also??

Until IMR lamps come out this would rock

SF MN21: 37W, 600 - 375

thanks again

Yes. I used that setup for some time. It used an MN21 in a KT2 on a Leef 2X18650 tube with two AW unprotected 18650. It was amazing but I have now changed the cells to AW IMR18650 which are much safer. Still just as amazing. :twothumbs I don't think the new LF IMR bulbs are going to be brighter than the MN21.

 

[Nite]

soft start or twisty?

 

[pete7226]

Nite, all of the bulbs you mentioned fit. I've used them all with twisty caps.

TnC also makes adapters (black and natural) that will connect a KT turbohead directly to an E-series body.

brunt, how are the IMR cells compared to those 2200mAh 18650s--shorter runtime but stays brighter? Safer because of the discharge rate being too high for the old cells?
I had the same setup as your old one with the KT2, but got stupid and sold all my stuff. Am about to be running the MN21 again on 2600mAh cells in a C-M body with Millenium Turbohead I miss it.

 

[brunt_sp]

I don't notice any difference in brightness. The runtime is a bit less but I haven't measured it. I did not have any problems with the unprotected cells but it appears that people in the know are saying the IMR technology is safer both in charge and discharge.

 

[mdocod]

To run the MN21 18650 is the minimum size, as mentioned, this requires either unprotected LiCo or LiMn cells. The LiMn (IMR) cells will drive the lamp a little harder (this is based on comparing discharge graphs of various cells).... I have been running the MN21 in an M6 on a pair of Emoli brand LiMn cells for quite awhile and haven't had any problems, but my usual practice is to rest the cells for 12 hours or more before using them in this configuration as the bulb is seeing a lot of overdrive. We have reports of the AW brand cell flashing the MN21 in this configuration, so even pulling it from the charger a little prematurely wouldn't be a bad idea.

Do NOT try to run the MN21 on any smaller configuration on lithium or li-ion cells than this.

Also... when used in "C" size bodies, the tailcap should probably only be a twisty, the Z59 would probably die immediately. The load of the MN21 is higher than any of the IMR lamps that LF is coming out with and they have already had problems with clicky switches on their prototype lamps.

That's pretty cool

With two IMR 18650 and a soft Start Z59..wouldnt this be great either with MN21 or LF equivalent?

Your specs says in your guide that this would use the cells up in LiCO in less than 30 minutes, much less than is safe

SF MN21: 37W, 600 - 375 lumen in 15-20 minutes (unprotected cells required, dangerous configuration)

And with IMR id get one third less runtime~!

Not worth the 150$?

 

[mdocod]

15-20 minutes is a conservative estimate and is also considering that it should be terminated early to keep the cell health up in this configuration. Some of the better unprotected 18650s with higher capacities could probably run this for 25 minutes... The LiMn (IMR) cells will run the MN21 for at least 15 minutes. My Emoli cells give me right about 15 minutes and AWs brand out-performs them capacity wise by a good 15% or more IIRC...
