Agreed. That would go against the whole concept.
I tend to agree with you, and if so, it is quite a departure in design.
Please add me to the list.
Thanks
When comparing the proportions itās pretty obvious that, like it was said, head and tailcap are unscrewed.

Have a look above and next pleaseā¦
Really??
Or maybe you mean this is the case in the range above very low modes.
Very low modes like āmoonā and āfireflyā give relatively more blue, i guess the phosphor is not excited by very low levels of 450nm.
But why post that ?
Makes no sense.
Screw it.
And please someone send some proto 4s to the people who are still trying hard, not being lackadaisical.
Sure hope so !!
That is the coarsest threading I have ever seen on a lightā¦ orā¦ possibly an o-ring slot and a slot for a snap-on-clip. If it does screw together and cover the two slots, that seems like wasted space.
*I reserve the right to be completely wrong.
Double o-rings, good design.
Yup. If those actually are double-o ring slots, that would be good design.
However, at the tailcap, the upper ledge of the āo-ring slotā seems like it would be too shallow to actually hold an o-ring. Screwing in the tailcap would push that o-ring out of position.
Thinner o-ring 
I really donāt think so. Unnecessary, and other aspects that I have observed on this image are troubling.
For starters, putting an o-ring into a rough bead-blasted groove with some shonky anodising is really not cool. If you want to create a seal, do it competently, or donāt bother. That means precise machined surface finish and materials selection. Slathering it with grease may also help. If you dive, you might understand this a little.
But since this is what it is, it probably doesnāt matter at-all to most customers.
Itās not as if we have even seen these supposed double o-rings in-situ. Well if two are better than one, why not three, or four where do you stop ?
Do it properly and one is enough. Two maybe for a dive torch, but that comes with downsides too. Double the maintenance, and you never really know whether either, or both, are serviceable. A bit like flying twin-engine planes.
Is that a piece for sale?
What do you want for thirty odd dollars, rocketship precision?
You could maybe take it diving with double O-ringsā¦ 
Btw, talking about double O-rings in non-dive lights:
Lot of maintenance thereā¦
I heard back from Neal: āthis is not the final verison, they are test the colorā
Also, I hope this answers some questions:
(before anyone asks, this is one light photographed twice, not two lights)
What sorcery is this???
Really. I highly recommend looking through maukkaās reviews to see graphs of the exact path the LED tint takes through color space as the power increases. In great detail, he has published quantified measurements of many different types of LEDs. Itās very useful information, well beyond what the manufacturers provide.
