Ok. But I don’t wanna buy another dam flashlight. I wanna buy JUST a Wavien Collar so I can stick one in my C8 and kick Endermann’s Synios Beam’s Ass!!! 
Is that too much to ask? (Picture Jack Nicholson saying this.).
Notta.
Here’s an article on the MarineBeam.

IDK. Sounds like an aspheric to me. But assuming there’s indeed the much vaunted yet mysteriously elusive holy grail Wavien Collar in it then I guess at only 300 lumens and 700 meters throw extrapolating its performance over to an Endermann creation his throw numbers would then blind an alien on Mars. :laughing:
An excerpt taken from the Product Description link of MarineBeam’s website……
“Notice that nowhere in this description, or in the specs, will you find any outrageous lumen claims. That is because the long-range illuminator uses its efficiency to gain beam distance, not battery draining LED power. In fact, the best part of the technology is that the power consumption and lumen output of this lamp do not need to be unnecessarily high, because the lumen-density (Candela) is off the charts. So, please do not use our lumen figures to compare this lamp’s output or its long range illumination capabilities. Use the ANSI FL1 standard, which was devoped for the purpose of comparing flashlight beams against an international standard. As a point of reference, the Streamlight Stinger HPL, which is a very high-end, high-lumen LED flashlight, with a specialized long-range reflector, has an efficiency of only 64 Candela/Lumen. By contrast, the Marinebeam Long-Range Illuminator has an efficiency of more than 166 Candela/Lumen, so it can make two-and-a-half times more brightness with much less power, meaning fewer battery changes, and longer battery life.”
Geez. What’s not to like? I mean imagine if Wavien Collars were prevalent in the market in a bunch of sizes. Current BLF GT’s confirms could be considered equivalent to a penlight.
Lux progress is being held back!!! It’s outrageous!!! (Picture Al Sharpton saying this.) 
:person_facepalming:
Recycled light technology (wavien collars) are used in conjunction with aspheric lens. If you want to build something to compete with the GT or Enderman then I applaud you but I think you’ll find it harder than expected.
waviens have been researched by BLFer’s a lot - budget light forum wavien collar site:budgetlightforum.com - Google Search
“Recycled light technology (wavien collars) are used in conjunction with aspheric lens. If you want to build something to compete with the GT or Enderman then I applaud you but I think you’ll find it harder than expected.”
Hell ya it’s gonna be harder than expected when I can’ t even buy a 12mm Wavien Collar from anyone!
(Not that I could beat Enderman with a nuclear powered flashlight anyway. :weary: ). :laughing:
Heck Fire PinkPanda, even THE MAN himself is practically groveling to buy one of the dam elusive unobtainium friggin things. I kinda feel sorry for him. Reminds me of the mythical Tantalus. :laughing:
PS……
I can almost picture sum guy at MarineBeam going, “Nyah Nyah Nyah Nyah Nyah. Yoooouuuu can’t have one!” Well he CAN apparently he just has to buy the flashlight in their link and then take it apart. Maybe. Prolly welded together with titanium and inconel with red Loctite as a lubricant.
Look the Wavien Collar lust is prevalent everywhere!!!
This poor guy’s nearly gone crazy chasing this Ark of the Wavien Covenant. I mean it’s like trying to date sum hot female celebrity who also happens to be a billionaire while he flips hamburgers at Wendy’s.
Shirley sum one can talk sum sense into MarineBeam here.
People’s mental health is at stake here for Peet’s Sake, man. :cry: :person_facepalming:
So they’re “available” from several places, technically…
The small one can be extracted from the Marinebeam flashlight:
Unfortunately they aren’t allowed to sell them individually, and they don’t have the medium or large sizes anymore.
I asked them if they would sell me some for university research and they said they would check with the patent owner for me (Meadowstar), however it’s been a month since then and no news yet.
Projector back-reflectors can be ordered from places like this but will likely cost a lot of money, and they are also huge, like 6-12”
If you have access to some diamond hole saws or cutting discs, or EDM wire cutting, you cound get something like this and slice the top off to get a collar:
http://www.optolife.com/diy_projector_lens/M074.html
The final option is to get Phoenix Electroforms to make some custom collars for us.
It would have to be a group buy, because making the mandrel will cost ~$1500 upfront, however it would be less than $50 per collar and they would give a discount for large quantities so possibly down to maybe $25 per collar (for something about 1” diameter)
Factually Enderman I sit corrected. MarineBeam merely licenses the collar from Meadowstar Enterprises of East Meadow, NY., as stated in their Product Description.
Maybe one can talk directly with them first since MarineBeam really IMO shouldn’t be in the middle unless there’s sum exclusivity arrangement with them and Meadowstar.
What I really want is a collar with a smaller opening than 60 degrees, less lumens but more intensity for use with longer focal length lenses.
PS- the reason I made a WTB thread is because I don’t like taking apart old projects to build new ones, and I will 100% need a collar for my next project.
Also I dropped my large collar from like 2m high, luckily it didn’t break, but it scared the crap out of me and it would be nice to have extras 
Well let me ask you this. What kind of numbers could you achieve?
I believe what prevents Chinese from making their own collars is obscurity more than legalese. But I may be wrong.
Making a similar device as a simple aluminium reflector is simple and cheap. Not as good as the original, but way better than nothing.
This is a cheap price, and it’s not that hard to cut glass even with a Dremel.
I already cut some ZWB2 UV filter just with a standard cutting disk and then a grinding drum on my Dremel.
I would try it
No idea, because it’s a non-linear increase per angle of light collected.
And the only “collars” tested so far have all been 60 degrees opening.
60 degrees is pretty good, allows for a reasonable focal length, and doubles the intensity, but it could be more than 2.2x if the opening was smaller.
If I could get a custom collar made by phoenix I would test stuff like 30 or 15 degrees to see what the trend is like.
Don’t really have a spare $2k at the moment though, and I doubt there would be hundreds of people interested in a group buy of a $50 reflector, this is budgetlightforum after all.

I think X3 may be on to something principally becuz doing the rough top cut shouldn’t be difficult but most importantly the center hole can then be micro-incrementally sized/centered as you see fit. I think that’s huge.
Prolly need a real machinist like a MrsDNF or VoB to chime in here perhaps. IDK.
Of course 64mm-68mm may not be there to begin with for what you’re trying to achieve either. But as you say establishing a trend could make even those restrictive sizes useful.
Good to know I can cut glass with a regular dremel tool.
I would probably put the cutting tool on a mill at high rpm and then just go really slow to slice the top off.
And yes, slicing at different heights would give different size openings
The only problem is that (based on the images from optolife) that focal length number is in front of the reflector, not the actual focal length of the reflector.
If you take a close look you can see that it’s not a perfect hemisphere, and if it was the 68mm diameter would make no sense, because the focal length should be half the diameter (not including the thickness).
So yeah, maybe I need to keep looking for true hemispherical reflectors.
They are really cheap though, maybe I could use them for testing regardless.
Not a lot of light is emitted at those extreme angles anyway.
Never mind, I found more spherical reflectors! Just on a different part of the site:
http://www.optolife.com/front_surface_mirrors.html
They’re really cheap, it’s worth to try it IMO 
Yeah I’m just confused about how the diameter is 4x larger than the focal length 
it shouldn’t be much more than 2x the focal length (aka radius)
Also more spherical reflectors here, but none that make a perfect hemisphere, they are all slightly less: http://en.hb-optical.com/products_detail/productId=145.html
Next time I order form optolife I’ll get a bunch of different spherical reflectors to test out.
The products are cheap but shipping isn’t
