I personally don't care about the darn Donut... This is not a light made to win White Wall Hunting at 3 meters contests.

I dunno, I tried using my SMO reflector with the Tiablo ACE module and the resulting donut hole was very noticeable even on trees and rough terrain - quite annoying actually.

How any self-respecting "flashaholic" could not care about a big F A T black spot dead smack in the middle of the beam is beyond me.

..are we looking at the same picture??? :nana:

Try making a hybrid reflector, half SMO reflector on the outside and by the MCE OP.

Olight does this with some of their lights.

This is the Olight T15.

Something similiar to this reflector.

This many help eliminate the hole in the beam while increasing the throw of the light.

I think that although the donut hole is by no means a deal-breaker, a simple
alteration in reflector design may help to reduce it significantly.

Whether its by sputtering or by a slight alteration in the geometry of the curve.

Surely, if this is all this takes, then its worthwhile for everyone?
I mean nobody is going to complain if is less pronounced,
even the macho, "I'll take it how it comes" amongst us. :nana:

Perhaps neoseikan has already exhausted all the possibilities, but I don't know that.

I am sure he is looking at the feedback and considering the options.

I know this is kinda late, but I think the regulator needs to be redesigned to work in boost mode to supply 18-20 V to power this sucker that I just came across on KD: http://www.kaidomain.com/ProductDetails.aspx?ProductId=6809 :crackup::tinfoil:

Yikes, that would be one powerful light. My P7 & MC-E lights now look terribly weak :sick:

BTW, anyone know the model number and who makes that led - looks crazy. Smaller than that huge & inefficient array on DX. This thing is quoted to have between 53-79 lm/W, not too bad.

No alterations in geometry will work, because whichever way you project the image of the emitter, it will still remain an image of FOUR (separated) dies. Hence, there will always be a doughnut. That's the way it is with multi-die emitters.

You could alter the reflector shape to get a more defocused hotspot (which would eliminate the doughnut), but that would yield you extremely reduced throw.

Hi. People. We just completed the new feature:

You can unscrew and remove the battery tube of Legion II to clean the ring or replace the spring now. The design has been applied to all the new Legion IIs.

This is good news as it was much harder in the S2 although it can be done.

Can I ask if you will be including a spare ring and spring,I feel this would install confidence even more in this design and also save on down time of the light should either fail.:D

Great job so far Neo :twothumbs

Yes. Spare Teflon ring & SWP-B spring will be provided.

Emitters such as that one are old news, really.
Check the dimensions.

Didn't see this particular unit before - the other 12W+ ones that I have come across before had distinct dies visible ala P7 & MC-E (plenty on DX), this thing looks like a continuous slab of substrate with connection pads or would those be the actual blue led emitters ? scattered around.

Oh, but yeah, see dimensions now ... bummer.

Re: NEOFAB Legion II, the powerful MC-E light &COMP with M1X, pic heavy!

I've seen some that look like a bit like crackers up close. Similar to Lux K2's, only with actual patches of semiconductor (blue LED's) in place of "holes".

Those darkish blobs on this one look like something similar.
48 visible blobs = 48 emitters in 6 groups of 8, probably connected as 6S8P, that would be 3-3.3V, 350 mA per emitter.

I'm not saying that the donut or the cross can be completely eliminated, but a change in the curvature of the parabola will alter the size
of the projection of the donut, just like the image of oneself in a mirror would change depending on the curvature of the mirror.
The idea would be to make the null area projected smaller, if possible.

Re: NEOFAB Legion II, the powerful MC-E light &COMP with M1X, pic heavy!

But that would make the doughnut appear even sharper!

Perhaps, but then use judicious sputtering in conjunction, as one or two of the previous posters have said.

Its a balancing act as I'm sure you're aware, but I have several lights with P7 emitters that have achieved a reasonable combination
of throw and spill without a very obvious void.

I'm not sure looking at the bottom beamshot, that I would say that is the case here which is why I think its worth trying for a better balance.

Yes, it's a balancing act, but Legion II is all about throw, not balance :)
On top of that, this isn't a P7. It's pretty much uncharted territory as far as reflectors are concerned.

Updated:
OP reflector has been test. The donut hole was reduced to the level of M1X.
Users can choose their favorite reflector, or purchase both of them.
