Mini Turbohead M2-XML2 Direct Drive

[PoliceScannerMan]

I ran a 3100 AW I charged last night to see how long it would go. Battery was off the charger for 14 hours and maybe used for a minute before my test.

It ran full brightness it seems for at least 45 minutes. At the one hour mark it was probably 200 lumens. At the 1:15 mark it was 3-5 lumens. It was the same at 1:30, where I concluded the test. Wonder how long it would stay at 3 lumen??

Great to see these are reaching the hands of you guys.

If you want to lego, or use a spacer, a SINGLE CR123 primary cell will run this head for a couple dozen hours.

Really? At what kind of output?

Jeez, I have to stop reading these threads. I just bought an OR Defense Light, now I'm seriously thinking of pulling the trigger on this... killing me.

Darvis, go for it. You will be pleased. Worst case you sell it for $20-30 less than you paid.

Even after 2 years, there are more WTB threads for the original M2-50 version than WTS threads. Most seem still to be with their original owners.

Intriguing setup. I'm curious, does it use a dropin or is the LED sealed in the head?

I know I won't be parting with my M2-50 and M2-XML anytime soon, especially the M2-50...very well made and cool setup. The only thing missing is not having another mode

In an M2, the top of a P60 reflector normally stops some distance from the lens. The throw performance from this setup comes from the reflector being much taller/deeper than a P60 sized reflector, taking full advantage of the larger size of this bezel.

Like our Triple E2, the parts are built into the head (think ship in a bottle). They are to large to be inserted as a set and to reliant on the 'case' of the bezel itself to be removed. In fact, each head is sealed with Loctite during final assembly.

Will the Head be available by itself? I already have a OR Custom C2.

We're working to boost production and will have solo heads soon.

As a regulation-fan I prefer stable output, but think it's acceptable with a slight decline during a certain time if that is not much noticable for the eyes. Is there any information available of what I could except from this direct driven device?
A runtime graph or, for example, XX% of initial output after 0,5/1 hour with a certain 18650?

 

[lightdelight]

Runtime will be directly related to the cells, and I don't imagine this is a light you would leave on continuously.

I ran mine continuously with no problems, heat sinking is nice, the whole light warms up, pretty hot but not too hot to hold.

Brightness held pretty even to my eyes for 40 min, then gradually down for another 20/30 min then dropped to 5 lumens.

I rather it do that, then just shut off from 1000 lumens to 0 then your stuck in the dark. Nice IMO.

Impressive! I'll probably pick up one of the solo heads then.
Is it possible to replace the lens or is it in there for good?

We have installed top quality glass with a multi layer antireflective coating applied to both sides. This glass has 99% light transmittance.
If you happen to damage the glass in the head, we will replace it under warranty at no charge.
It is not user serviceable

 

[ElectronGuru]

Impressive!

We have a simple philosophy: first, do no lame

If the first one doesn't work well for us, we don't bother making a second.

Thanks for sharing that experience, pretty good description of a runtime graph!

Oh really?? Hmmm.... Time to free up some funds!!!

 

[Zigo45]

I was wondering if the inside measurments were the same for a M2 head and a M2 cryos cooling bezel. If so, would it be possible to build one of the M2-XML2's into a cryos cooling bezel?
