Shouldn't Lumens Factory Have a Turbo Head?

[ampdude]

Updated externals as in.. maybe a grip surface around the edge of the bezel would be a cool improvement. Even just lines would be fine.

I think even a 2.5in version that is very close to the SRTH would be awesome because it would be slimmer than the SF alternative and throw better. But a 3in would be cool as well. I'm up for both as long as they don't have the extra metal bullshit hanging off of it that most aftermarket stuff does.

How well it throws depends on the reflector not the size of the head.

I would be interested in one 2.5" M/C turbohead. Are they going to be black and natural?

Cheers,
Nova

I don't see how lumensfactory could improve much, if any, over surefires current 2.5 inch KT heads.

I estimate that my SRTH delivers about 2X the hot spot lumens (when using LED towers) vs the usual KT1/2 and KT4 THs. I forget what the improvement is for incan towers, but it is there. So it seems quite easy to envision how LF can improve on the current 2.5 inch KT heads. In addition, if the LF head is optimized for LEDs, I can easily envision even greater performance vs the SRTH (which was designed for incans). And for optimized incan use, a slimmer profile head vs the KTs IMO would be a big win. I dislike the chunky size and sharp edges of the KT1/2. A glass window vs the SRTH´s Lexan may allow even higher powered lamp usage.

Hi Justin, just wondering, if the SRTH is the superior turbohead then is there a particular reason why surefire discontinued it and chose to replace it with an "inferior" turbohead, the KT design?

 

[ampdude]

Yes, I doubt Mark would use lexan. I would imagine some type of glass, probably borofloat. Though I think hardened mineral glass would be the best for overall toughness and could be thinner than borofloat.

And I'm hoping the glass is easily removeable for cleaning and replacement. That's almost a must for me. Hopefully it will use some type of removeable retaining ring.

 

[ebow86]

What is it about the SRTH that makes it supposedly superior to the current KT offerings? A deeper reflector? A smoother, less textured reflector? I never used one so I can't comment on it's performance, I just don't understand why surefire would discontinue the SRTH and offer a supposedly inferior design, the KT.

I don't see where that would be nessecary. As long as the glass is clean when it's installed, which it typically is, the shouldn't be any reason to clean anything but the outer front exposed glass.

Hi Guys,

Sorry for the delay in this project.
We have been busy with the E Series LED Heads recently and experienting on warm tint LEDs as well.

We have this planned and I will get back to it tomorrow and hopefully bring it out soon.
I am looking to make it in a M thread platform, so it can be used on both the M Series and C/P Series with a M to C Adaptor.
Rest assured that we will not let the mighty incan die off that easily, we are a bulb maker by trade so we will do our best to keep it going.

Off topic a bit, we have got emails asking if we will discontinue our incandescent lineups since Surefire seems to be fading them out.
The answer to that is NO, we will keep our incandescent lineup available and will expend it even if we need to.

Cheers,

Mark

Just a friendly bump. Since I'm sure all of use die-hard Incan fans are still drooling over a Incan turbo head!

Still nothing???

I was just thinking about this thread the other day. I'm seriously doubting this will ever happen since it has been so long now and Surefire has pretty much discontinued everything incan, except the 6P and G2 from what I can tell.

On the other hand locating even a Surefire KT turbohead is getting difficult. I good sized run of these I'm thinking would sell out quick..

I'm still hoping LumensFactory creates a SRTH 3" head

I think that one would for sure get added to my spare parts stash if and when available.

 

[Mark@LF]

Wow, this thread got necro'ed?
Well, someone actually called me the other day to ask about these.
I am still interested in making them, just not sure if they will sell.

The other problem is that "Old School" Flashaholics that actually know what these are are getting scarce and people who actually want to buy these are even harder to find.....
The M Series lamps and MN lamps are probably the only lamps even available now.
If I duplicate the exact reflector of the SRTH that is for the N62, it will not yield the optimal results. (although it will still be pretty good probably better then most turboheads nowadays, just not as good as the N62)

So yes, I am still interested, but there are much to think about before I actually make these.

Cheers,

Mark

 

[Juggernaut]

Still interested!:twothumbs

 

[Mark@LF]

Love that signature, Juggernaut. So true. :twothumbs

Well, I'll look into it then.
Probably need to sacrifice a SRTH in my personal collection to make this happen, but I guess what needs to be done needs to be done.
For some reason, I always feels good with Incan projects.
Got a feeling that we might not sell much of this, but I will see what I can do here.

I need to ask you guys a question though:

Would it be better for this to be on an M Series thread or C Series thread if we were to recreate the SRTH?
Also, would it be better to make the 2.5 inch SRTH or the 3 inch turbohead?

Read some of the old posts as well, sure as hell I will not be using Lexan for the lens.


Thanks.

Mark

3" M-series for me. I've always been under the impression that the LF 3" Turbohead would be an "improved" beam version of the KT4. If users want to attach it to a C-series head, just use the C-M adapter.

You reckon that this wouldn't sell in large volumes? Maybe, compared to all those new fangled LED thingys, but wasn't this project about a passion? Perhaps I liken this incandescent vs LED thingy to old school V8 muscle cars vs multi-valve high boost turbo rice burners... there's till no REAL substitutes for incandescent or cubic inches and cylinders.

If you could work out the price of each turbohead would a 50% paypal deposit(refundable) be enough to determine if the project will go ahead?

I'd be in and 2.4 or 3 inches is fine by me though we must consider that 3 inches means we can't use our FM24 diffusers. I'd vote for M-Series compatibility too because you can always fit an adapter to use on a C-body.

Besides a turbohead, I was hoping for someone to make a P60-drop-in-compatible M-series head so we can use Malkoffs, Oveready triples and other drop-ins that can accept two or more li-ions in series. Good, compact back-up in case a bulb fails. The extra mass and surface area of an M-series body also helps with the triples and higher-powered Malkoffs to dissipate heat. Technically, it's difficult given the depth of the M-series head/collar but I think it can be done. An alternative to this is to design a special adapter to fit a Z44/C/P/Z-series head on an M-body but that would be more complex and add more contact points as a piece of brass will have to form an interface between the battery positive contact and the spring of the drop-in.

Definite interest in a 3" TurboHead !

I understand the preference of many for the M-series threads, but I have so many more C-series hosts than M-series, and I dislike the added resistance / decreased body strength / increased complexity / increased cost / mismatched appearance - (pick one or more) ... of having to use adapters

I would like to lodge a friendly protest against this!!! The C-series bodies already have the KT1/2 heads which do not have the pesky shock-isolation foam that the KT4/M-heads have! Although they're rare, they're more common than SRTHs and do show-up in the marketplace. Moreover, all the recent M-series heads have shock-isolation foam. Again, you can always screw an M-series head on a C-body but a C-head can never be placed on an M-body. M-series users have been neglected with regards to aftermarket accessories compared to C-series users!

OK, ok ... I'd probably "buy both" - :devil:
