How do you think this will stack up against the SC64w Hi in terms of output? I have the SC64cLE and the w Hi and there is a noticeable bump in output with the Hi. I told myself I wasn't going to buy another Zebra till the new SC700 is released....
SIDENOTE-I downloaded Jerboa for Lemmy and it really makes for a decent reddit'ish experience. Thisight just work. ;). Thanks for getting this ball rolling.
Probably a bit lower than the XHP35 HI, but maybe more throwy.
I tried Jerboa and it didn't want to stay logged in. I'm pretty content with the mobile website though.
Sounds like it'll be perfect for those who wanted a w Hi but didn't get one. 👍 Maybe I'll save my money for the 700.
No matter how many times I set it to English and save the settings, the website would always default back to Arabic. Not sure what I am doing wrong. I just got Jerboa set up I guess I'll see how it goes.
I worry about the huge flux range. Most emitter bins are like ±4-5% flux. 719A bins are ±10% flux. So theoretically you could be looking at close to 20% swings in lumens and throw from emitter to emitter. And you can't drive them past 2.5A so you can't drop one into a D1/KR1 or any lights really since most 6V drivers are 4A+.
Hopefully they are more throwy than an XPLHI or XHP35 otherwise idk.
Do we know how hard they can really be driven? Zebralight won't drive them hard of course, but they don't drive anything else hard either.
Djozz tested some that Simon sent him on BLF and they permanently failed above 3A. Mcbob said the same thing in the comments in regards to his own testing and said he doesn't think they should be driven above 2.5A.

Above 2.5A CRI drops under 90, Duv and CCT go way up.
Ooof that's a big swing. It might even be more or less throwy than XP-L HI/XHP35 HI depending on the flux lottery.
Plus with 3000k/4000k high CRI SFT-40 coming out there's going to be even more competition for warm/neutral, high CRI throwy goodness. Of course I wouldn't expect the tint to be much better than SST-20 4000k (fingers crossed, but it is luminus we're talking about here lol). Maybe there will be something similar to the FA4 bin.
So, biggest advantage I see 719A potentially holding on to is consistency in tint. XP-L HI has some consistently awesome bins, but also some bad ones, and I don't know if theres a lot of 90 CRI ones with good tint, only 80 CRI. XHP35/.2 HI is much more of a lottery than XP-L HI in my experience - some fantastic, some pretty green. There might be a consistently good bin, but afaik there's still availability issues with finding consistently good tinted XHP35 HI's in large numbers, especially in 80 or 90 CRI.
So if 719A can have the same consistently good tint that other nichia LEDs manage, then it makes a good case for itself, as long as it can get close to as throwy as XP-L HI/XHP35 HI.
But yea, if the performance isn't there, or is wildly inconsistent, then that could really make it meh central.
But if ZL are putting in the successor to the sc64w HI, then my hopefully guess is that performance is at least competitive.
Yeah it's probably not likely you will get one that is to either of the extremes of the flux range, but technically it's possible. It makes sense considering they are stacking 2 dies. So each die on its own has a ±5% flux? I'm really interested in knowing how they make these and how exactly they work. Like does one die have more impact than the other die? If the bottom die has low flux is that better or worse than the top having low flux? Lots of questions in my mind about these things.
This might be my first zebra. Been wanting to get one just for practical use (efficiency and durability).
You wont be disappointed.
Great news. Thanks for sharing the good ZL news.
"Estimated ship date: mid July"
Do you know the timetable for Simon getting 719As in his lights? Last I heard it was supposed to be ~May-June. He might beat zebralight to the punch with the first 719A light.
I don't. I know he got a few emitters to experiment with, but it's anybody's guess when he gets them in quantity.
