The Miller…. the Cometa pill was made WRONG…………. nothing more nothing less.
The problem had Nothing to do with battery contact point sizes. End of story on the Cometa. No reason to post anything other than the Cometa pill was made WRONG.
And because one person has posted he bought a 22mm driver does not make this a “no brainer” to make it 22mm.
Making it 22mm has nothing to do with “safety”, otherwise there would be no 17mm option. :person_facepalming:
Now if it is because the 22mm option offers “more options to more people”…. fine. That is fact and I would have to agree. I just hope it does not significantly increase the price.
Hmm I only referred to the Cometa as example for possible dangers.
It is simple logic to me that a - connected ring with a size lots of + sides of 26650 cells can easy touch poses a non ideal situation being most drivers we use have a spring to connect the + side with the driver and springs are made to be compressed. If a brass/copper cap would be placed on that spring yes then it would be certain the + connecting side is highest part of the driver and thus safe.
None of my decent 26650 lights have a 17mm driver (or it cannot be seen thanks to a plastic protective disc covering all but the spring to the driver), off the top of my head Orcatorch WR10, Convoy BD01, Convoy BD06, On The Road X5, No name dual LED, Jaxman Z1, Convoy L6, Thorfire S70.
I do have some 26650 lights that have a pressed in driver (those G700 Ultrafire ones and the not easy to take apart Warsun X65 seems to have a pill pressed
And some other cheapa$$ 26650 zoomies
In these cases the spring ia (even fully compressed) the highest point
So that makes them all safe on this part.
Please point me to a decent 26650 light with a 17mm driver held into place by a ring and I stand corrected that it can be done safe.
22-17mm adapter boards are cheap and easy to get. So I really miss why a default 17mm hole is more versatile then a 22mm hole.
Also I miss why drilling and threading a 22mm hole would be more expensive but I am not a machinist so apologies for not understanding that.
HOOP, I thought that ALU is better in heat transfer then brass so maybe make ALU pills? That would be an improvement to the stock pills, easier to make and cheaper right? (Again please correct me if I am wrong here )
The brass post is the diameter of the spring, typically, and enough length that the cell cannot possibly touch the retaining ring… this post replaces the spring on the driver, and as such, you must have a spring at the switch or you’d have a battery crusher style which could be compromised by a drop, breaking contact and rendering the light unusable.
I have, on an occasion, drilled a small hole in the brass post on the underside to line up with a through hole in the driver such that a wire could be passed through from the brass post directly to the emitter for best possible current transfer…
The Miller, I am not trying to argue. I am simply saying if a pill is made correctly and the proper spring is used on the driver…. there will be no issue no matter what battery is used. Or in place of a proper spring use a brass button like Dale suggested.
The Cometa is only an example of complete failure in the areas mentioned above. Nothing was done correctly. :person_facepalming:
Took my 2 Z1’s to the lake a week ago. Wanted to see what the difference in throw would be. Here are the results:
XML2 U4 1C on the left
XPG2 S4 2B on the right (old stock)
Both are dedomed
To the naked eye, they both look to be about equal brightness. The XML obviously has a much larger die so it produces a larger “square.” But side-by-side, the lumens on the trees look to be equal.
Those trees are about 600-650 feet away according to Google Earth.
I just got back from testing my Z1 down in the ravine. Awesome!
The HXP-35 HI is about as perfect in this light as you can get. The throw is amazing when zoomed, lighting up the distance with full clarity, and there isn’t any annoying visible matrix.
When deployed in spot mode, it will easily illuminate the entire infield of a ballpark well enough to play. (I was standing at home plate)
I do love what’s coming out of this build, but you also have to realize that I have nothing to compare it to, such as the same Z1 host with an XPL HI. Besides the XHP-35 being 12V with four mini dies, I have no idea what the visual comparison and output would be between the two. Besides that, I’m impressed enough that I ordered another host last night.
Now I have to decide what to put in it.
