Surefire KT1 Turbohead / Leef Combo - finally got everything!! (pics)

[RichS]

I searched and read, but unfortunately I couldn't find a definitive answer to this so I just thought I'd ask the experts a question. (please have mercy if I missed a thread answering this..)

I have several Leef/SF legos, and I wanted to get a SF turbo head to go on my 2x18650 Leef body. First, I want either the KT1 or KT2 head - I believe they are exactly the same except for the lamp that comes with it. Is that correct? If that's the case, I'll get the KT1 since it's a little less expensive.

Secondly, my 2x18650 Leef body is a C to M body. Will the KT1/KT2 fit the M head, or do I need to by a C to C Leef? I couldn't tell if the turbo head came with an adapter that just made it fit a C size head, or if it only works on a C head period. If that's the case I'll need to get the Leef C to C body.

Lastly - Do the standard MN lamps (MN16, MN21, etc.) fit in this? If so I can use the FM MN bi-pin adapter with this.

Thanks for your help!

-Rich

UPDATE: Well, I got everything and I'm loving this combo! Someone mentioned they wanted to see pics once I got everything so here you go..I actually bought an SW02 to go on this light, but I liked the SW01 on it better so I swapped tailcaps with my Leef/M3 host. I'm running an MN20 lamp in it right now, and boy is that beam pattern nice - the spill with this guy is HUGE! And of course it's throw is incredible.. Now all I need is for my FM MN bi-pin adapter to arrive and throw in one of my WA1111s....:devil:

Yup, the KT1 and KT2 kits come with the same turbohead.

Secondly, my 2x18650 Leef body is a C to M body. Will the KT1/KT2 fit the M head, or do I need to by a C to C Leef?

No. The adapter included in the KT1 and KT2 kits is threaded for C series bodies. The Millennium turbohead that comes with the KT4 kit is threaded for M series bodies.

Lastly - Do the standard MN lamps (MN16, MN21, etc.) fit in this?

Yes.

Make sure to post pics when you get it whipped together Rich!
Planning on using WA 1111 right?

Thanks so much! C-C Leef and KT1 kit ordered!!

Will do! Yep, the WA 1111 will definitely be one of the lamps I'll be using in this light. But actually, after using the WA 1111 in my M6 w/ 2x18650 and then switching to 3x17670 w/ HO-M6R, I'm pretty sold on Lumens Factory lamps. I like the HO-M6R way better. It has a much more focused hot-spot and a generally more throwy beam, which I tend to prefer in high power lights like these.

So, I may try the IMR-M3T (700 lumens) and I'll possibly also get the EO-M3T (450 lumens) for longer runtime.

BTW - anyone know where I can get a crenulated bezel for the KT1?

Re: Surefire/Leef Turbohead Question

Why not the KT2? would have come with a lamp that you could use as a LOLA on 2xli-ion

Oh, now you tell me!

I actually would have done for the extra$11 that had I known that ahead of time. But I do have a couple of SF MN10s. Would these work as LOLAs on 2x18650s as well, or would these push the MN10 too hard?

Re: Surefire/Leef Turbohead Question

MN10s won't fit. Those are for the M3, and are too short.

Ah yeah, that's right.. I don't know what I was thinking. So I guess no LOLA for me! :sigh:

Re: Surefire/Leef Turbohead Question

With 2x18650 you could use a MN15 or MN20 as LOLAs...

Good to know, thanks. I've got an FM MN bi-pin socket coming since I have a couple of WA 1111s already to run in it. Can you recommend any nice LOLA or medium output bi-pin bulbs that will work in this?

Thanks!

Re: Surefire/Leef Turbohead Question

I don't know about the bi-pin setups, but the Lumens Factory HO-M3T is a very nice, and safe(for the bulb), medium output option. It's what I use on 2x18650, and would be my choice for the M6 with primaries, too. It has a 2A initial draw, and should offer a solid hour of runtime in either, probably more in the M6.

Re: Surefire/Leef Turbohead Question

GE787 draws a little under 2 amps and performs as well or better than the MN20 in this application. I find it to be a nice medium-low bulb on 2 li-ion cells. It's not driven so hard that it's on edge either so I'd say it has some reliability on the table as well.

I agree about the LF lamps - the HO-M6R is one of my all time favorite's now. It is nice to be able to drop it in and go, with it perfectly focused. And how do the get all that throw?? I'll probably get one of these eventually, but the bi-pin bulbs are a lot cheaper..

Perfect, thanks FM! I was also glad to see you're offering a shorter neg. spring with your adapters now. These continuous improvements and adapting to the need is what makes your products such hot commodities!

Great option, thanks. This will probably be my most used bulb for this host. Very practical while still putting out plenty of light. Also, since I'm going for SF and Leef quality and toughness, reliability definitely does play a factor.

Not sure about the cost of bi-pin bulbs being much cheaper than the SF, LF, WE lamps. The average life of the more common WA bi-pin bulbs is about 4 to 8 hours from Luxluthor's data. The advertised life of most "lamps" is between 20 to 25 hours, so in reality, not much difference in which way you go.

Very good point. You know, just when I think I have this stuff figured out I find out I still have so much to learn...

Well I got my KT1 today!! This thing is just plain awesome! I don't have my 2x18650 Leef/SW02/FM bulb holder yet, so I thought I'd try it out on my 2x18500 Leef with the N1 that it came with.

My 18500 has an AW 3 mode switch on it, so I turned it on to low, then medium, then high...wow - look at that nice hot spot!....

Yep - took about 5 seconds to blow the bulb. I guess you can't run a 6v bulb on two 3.7v li-ions....Oh well, I didn't have big plans for the N1 anyway.. I went ahead an put in an extra MN20 I had per DM51's suggestion, and we're good again. :twothumbs

So, here's the interim build until the rest of my stuff gets here..this thing is going to be a beast!...

It's all business....

Luxluthor's data is very usefull for some people while confusing for others which needs to study more.
I have no idea where you got 4 to 8 hours bulb life but it depends on what level overdriving you push to, your set up resistance, battery sag and ...
You will get more than 40 hours of bulb life with 2 li-ion and WA1274 while you will never get such a life from P91 with same battery set up.
Generally (not scientificaly) any bulb which is rerated 4 to 8 hours in specific set up will most likely instaflash unless you have a soft start.
If bulb is rerated 3~4 hours may even flash with available soft start unless soft start is designed for longer time of 20% to 100% voltage raise.
Again all statements above are much more complicated that I explained but might be usefull for you.

I know what you are saying, the data is a guide only but I refer to it quite a lot.

A while ago I worked out the resistance drop on one of my lights and it was a loss of 1.2V. Since then I have used the figure between 7.2V to 7.4V on two Li-Ion cells as a guide, and 11.4V to 11.6V on three cells to select any future bulb purchases.

You are right about the 1274, at its default level of 7.2V the life is about 40 hours. Most others are much shorter than that; 1111 7.2V 11.2 hours, 1331 11.4V 4.5 hours, 1160 7.2V 6.9 hours, 1185 11.2V 7.9 hours, (no 11.4 in data) the P5761 7.2V 11.2 hours and the 1794 7.2V 7.1 hours.

I am sure that people will get more out of the bulbs than the data suggests but overall I don't think that they last as long as most "lamps" that are designed for two and three Li-ion cells.
