Relevant for monochromatic sources or applications where radiated energy is important - watts out vs watts in. Less so for determining the performance of white light which needs a good distribution across the visible range to be useful for human vision.
Standard for flashlight advertising ever since we stopped obsessing over candlepower from low-lumen incandescent filaments 20+ years ago. At least today’s “low CRI” LEDs are typically ≥70 as opposed to the ≤60 CRI of a decade-plus ago.
A KR1 style light with head diameter <28mm, and would make it more useable for light painting.
So meaning, from members knowledge. the new boost driver will have gain and lose and also how much gain/lost depending on LED option. How much gain and lost will depends on individual needs.
For the options now, the gain(significant), the lost(insignificant) will be the Nichia 219B from a 9A linear to a 8A booster….
Will we ever see an all brass KR4, or is that option in the Secret Menu?
So why new boost driver is limited on 2A per led? It is impossible to put inside flashlight bigger inductor? Or does the price and complexity of the driver increase noticeably with more power? Does it make sense to wait for a new driver for, let’s say, 2.5 or 3A per led in future?
Using charts from reddit, I calculate that in best case we will get 2400 lm from 4x 519a with 2A per led. Of course, I wish there was more.
3A12V/6A6V is about the maximum reasonable power with the MP3432 boost converter used in these drivers, but indeed it would require a larger inductor than the one currently used, pictures of the D4Sv2 driver were posted and reddit and it looks like a 6030 sized inductor (~6.5x6.5mm, 3mm tall), something like 6060 or 7070 inductor would do but the D4S is limited to ~3mm, the KR1/KR4 body has been updated for the boost driver but probably just to 3~4mm (?) and not to 6~7mm driver cavity height.
i had been thinking Lately how awesome a 14500 KR1 would be!
OR,
a 14500 version of the D1 !
Reflector please!
I personally don’t think 14500 (or 18350) have enough capacity for hotrod lights - it’s like trying to power a Ferrari with a 10litre fuel tank. I don’t go smaller than an 18650.
On top of that. How’s the focusing of the beam going to be? Even the Antman, which is a LEP struggles with focusing.
Ain’t gonna be a pretty thrower.
well that's the thing, I've been on a "lower power / sustainable / less heat/ small light" kick. So I wouldn't want this Emisar/Noctigon 14500 to be a hot rod (my opinion, i may be in the minority here)- but i would love a sustainable, superbly made 14500 single emitter light (thinking Skilhunt m150 or ZebraLight or picl one), but with all of the amazing custom options Hank offers (emitters, tints, cri, drivers, ano colors).
basically everything there is to enjoy about small lights (pocketability, light weight) but with Hanks plethora of options. THAT would be the selling point in my mind! No V10 needed :))
basically - no other company is offering all of these options in the AA / 14500 size. Hank making a single emitter light with his "normal" options would dominate that market!
Not really honestly.
I believe Emisar is at a point where there are too many choices for LED, options, secret options, etc.
If he wants his light to dominate a market, he needs to go mainstream. That’s it, that’s all.
ehh, I mean maybe I misspoke. It would dominate the enthusiast market. Not mainstream, but we aren't the mainstream flashlight crowd (if there is such a thing). We are enthusiasts. I don't think there's too many options, only for the new people. But once you get the hang of what cri and tint are, then it's not bad. I mean the new boost driver stuff throws an added element of complexity, but to the average user or a newer enthusiast, the boost driver is a territory they need to not worry about (at first).
I just mean, for folks like most of us (people on a flashlight forum), options are key. If I could get a ZebraLight sc5 or sc53w in different emitters or tints, I would probably own multiples of them. But I've never bought one and probably never will, bc I have no interest in paying $55 for a light that I can't choose the tint/cct on.
I think Hank would do well in the AA / 14500 market, not to mention it would be something unique because that's how he operates.
Hank’s lights are aimed at enthusiasts rather than mainstream muggles.
Artie, I am right there with you… an FWAA’ish light with aux lights or a well built equivalent of the FWAA in a useful single emitter, not an Osram, would be the nuts some days want I do not want to throw the FW3C or KR4 in my pocket. Sometimes it is all about output, but many times it really is not and I could and would charge after a long day with lots of runtime.
I’m hoping Hank’s 14500 light isn’t a hotrod. Perhaps Sofirn’s SP10 Pro is all the enthusiast non-hotrod 14500 market needs, but I suspect there’s room for an offering from Hank.
I also hope it’s not a hotrod. Here’s the feature set I’m hoping for:
And it would be nice if it would be smaller than the 18650 SC64 Zebralight.
You all have seen every single light made by Hank.
Is it really a Hank light, if you can’t burn a hole into your pocket or empty your battery in 10minutes?
Yes, 5amp KR1. One of his best honestly. Long turbo / runtimes. excellent LED choices (xpl-hi, osram, sst20, 219b, 519a, etc). Output is more than needed in most situations.
a CC 5amp 14500 single emitter Hank light would be perfect.
I will text him to remove this light immediately from the site. It doesn’t fit
