    The Official Zebralight Thread

    Yeah, this is totally a thing. Not something that happens often, but can cause quite a bit of annoyance when it eventually does.

    Older version has slightly longer runtimes (by less than 10%, in theory).

    The Official Zebralight Thread

    Okay, an update on this since ZL's sales dept got back to me. According to their response, it's not the output that is different (they have indeed designed it to match the non-LE versions), but the runtimes. So yeah, those should be proportionally lower then. I also asked them about the new...

    The Official Zebralight Thread

    Has anyone noticed that output numbers for H53c LE and H53Fc LE seem to be copied wholesale from their non-LE counterparts? Hard to believe they've matched it precisely for two completely different LEDs with different output specs. Going by the difference between SC64c and SC64c LE which use the...

    Zebralight SC700d 21700 XHP70.2 90+CRI

    Going purely by the specs: XHP50 in your SC600Fd IV Plus is rated at 3 A at 6 V; XHP 70.2 in the SC700d is rated at 4.8 A at 6 V. So, with operating voltage being equal, in the worst case the new LED will demand a 4.8/3=1.6 times increased current draw on the battery, so 6×1.6=9.6 A. And indeed...

    Zebralight SC700d 21700 XHP70.2 90+CRI

    Let's be honest here, Nichia's "foothold" in the LED light market is really tiny... It all amounts to low-volume enthusiast-only lights. Nichia has no presence in consumer flashlights otherwise. I wouldn't worry about knock-offs (...has anyone actually seen those?) in high-performance lights...

    Zebralight SC700d 21700 XHP70.2 90+CRI

    To be fair, the main reason why this is the case is that the end-user is not expected to take cells out by themself. Flashlights and Ecigs are the notable exceptions but they're also considered enthusiast items with all the expected caveats (e.g. the lack of safety certifications that would...

    Zebralight SC700d 21700 XHP70.2 90+CRI

    Dude, please stop. Your misguided criticism and counterproductive "suggestions" don't contribute to meaningful discussion and aren't really helping anything except making you look like a frustrated person. 1. It was never 4000K. Like Bob_McBob said, all "d" ("daylight") models are 5000K. 2. ZL...

    Zebralight SC700d 21700 XHP70.2 90+CRI

    Product page is up, max brightness 3000 lm as expected. No runtimes yet. Notes on the new info: — Slow strobe still at H1 brightness, which at 3k lumen is completely useless and even ill-advised... Oh well. :( — M1 got brighter, M2 dimmer across the board. — All High modes are significantly...

    Zebralight SC700d 21700 XHP70.2 90+CRI

    Interesting. The mk. IV lights using the 6V XHP series LEDs and the SC700 both use a boost driver unlike the previous versions' buck-only which doesn't have this problem (at least I haven't heard of it). There could be a (safety-related?) difference in their behavior under conditions that make...

    Zebralight SC700d 21700 XHP70.2 90+CRI

    Then keep your fingers crossed that the sales dept people manage to convince the engineer team to move the plans for the next UI generation forward. I shot them an email last week with regards to the fact that slow strobe will certainly be unuseful (and in fact outright dangerous) at ~3000 lm...

    Zebralight SC700d 21700 XHP70.2 90+CRI

    After thinking about it some more, I've come to a conclusion that it most likely won't be a >3000lm light. The reason is that the 90+ CRI versions of the 5000K XHP70.2 start at the brightness bin M4, and based on what I read in Cree's datasheets and the PCT, it can only squeeze out 3000-ish lm...

    Zebralight SC700d 21700 XHP70.2 90+CRI

    They're most likely sticking to Cree's offerings because they have the best lumen/watt ratios by far, especially among high-CRI LEDs. For a company that prides itself on extreme efficiency (in all aspects, not just electrical) this is an obvious way to go, so I wouldn't count on them using any...

    Zebralight SC700d 21700 XHP70.2 90+CRI

    Re: Zebralight new 21700 flashlight Which, incidentally, is the only pocket I ever put my EDC SC600 in. It's too bulky for almost any of my pants, anyway, and I don't use it often enough to keep there. I carry it in a jacket, backpack, or a Jack Wolfskin purse with my 8" tablet. The extra 8 mm...

    Zebralight SC700d 21700 XHP70.2 90+CRI

    Re: Zebralight new 21700 flashlight Both improvements entirely justified and long-yearned-for. I guess the company is aiming to catch up to and overtake the market for high-performance custom offerings. I'm expecting at least some 3500 lm on H1. :p
