Really??
Or maybe you mean this is the case in the range above very low modes.
Very low modes like ‘moon’ and ‘firefly’ give relatively more blue, i guess the phosphor is not excited by very low levels of 450nm.
That is the coarsest threading I have ever seen on a light… or… 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.
Yup. If those actually are double-o ring slots, that would be good design.
However, at the tailcap, the upper ledge of the “o-ring slot” 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.
I really don’t 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 don’t 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 doesn’t matter at-all to most customers.
It’s 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.
Really. I highly recommend looking through maukka’s 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. It’s very useful information, well beyond what the manufacturers provide.
