The CSLPM1.TG maxed out at 7.5A in djozz's test, while Texas_Ace tested an XP-L HI 1A V2 and it peaked at 7.25A. If you care for your leds, you have to set some limit in both cases.
I am working on a thread about the new throwers here
Let me know anything to change
By the way does the C8 holster fit M21A flashlight, or a little too short?
M21A has the same head as C8+ right?
Yes, but in the case of XPL-Hi the forward voltage was higher than open circuit voltage on fully charged battery - let alone on battery loaded with 7.25A. That’s why it’s safe to use XPL-Hi in single-cell lights with direct drive (no current limits).
For comparison, the 7.5A forward voltage of CSLPM1.TG was about 3.25V. We’ve repeatedly seen them over-driven or damaged by direct drive, with a FET and a half-decent cell you’ll get much more. This is why CC drivers are important.
All good - I’m playing with the Brinyte T18 now and once got it where it was defocused at full open. But I think I may not have tightened it enough or something.
That focus of the Z1 is not so bad, I doubt that you will see or even measure significantly less throw. I understand that he avoided a sharp focus, apart from aspheric flashoholics a sharp die projection is considered ugly. I made a few high CRI aspheric mods that I tuned to slightly off-focus too.
It is a bit of a disappointment though that the Z1 has a bit smaller lens and larger focus than the Cometa while not being significantly smaller in size.
I put white flat in a OTR Z821 recently and had to use thicker MCPCB (by 0.5mm) than stock. I found that after I shimmed the lens outward and adjusted focus manually I got ~7.5% more kcd and honestly I could not tell any significant difference in focus visually.
I just now tried another zoomie and ever so slightly defocused it and I see ~15-17% change in lux.
I guess ugly die projection and significant decrease are subjective but at distance these are intended you wont notice die anyways and it’s easy enough to underfocus LED manually after all this is what zoomies do.
For my comment on the above, see djozz's comment below.
I love the figure of the die projection, it's an identity sign of aspheric flashlights. It's beautiful.
As much as I understand that being judgmental is no good, there are times that I simply can't avoid it. To me, downgrading a product to meet the requirements of morons dimwits is a disservice.
Yes, the head of the Z1 is massive versus its lens diameter. Super thick edge. Could use a much bigger lens.
