The 4500k 519A from the graph was domed, right?
Then these results seem good to me, considering the dedoming process required to get the same intensity as 719A reduces lumen… So 719A would be throwier than 519A. And we can get to use 5000k and 5700k, and boost driver for a single led, single battery flashlight… Not bad!
It may not be revolutionary but this seems to achieve what a lot of us were hoping for with b35am. Is the voltage curve higher than for b35am?
Oh much higher! 6.7V vs 4.5V at 2.5A. [edit: correction, it’s slightly les than 6.1V, not 4.5]
Hank’s 6V driver measures over 7V when the leads are not connected to an led. Do you think we can expect it to handle the 719A up to 2.5A?
It’s about 6.1V at 2.5A for the B35A.
Well if it goes up to 7V is should be good enough, and ultimately it’s just one resistor change to shift the output voltage range upwards.
I just saw a new Convoy on AliExpress with the 719A and decided to check here.
I’m only a step above muggle level and have never tried to dedome anything.
So for someone who just wants to light up a reasonably large yard with pretty light–balancing throw and flood with a decent reflector, like on the M26C–how might this one stack up against a GT-FC40 or XHP70.3 HI at 2700, 3000, or 3500K?
Under similar optics or reflectors, 719A is less floody because it is a smaller emitter and this makes the beam more concentrated.
No. The 719a is a Throwy LED.
And it is installed in an L21b Long Range host.
maybe @cannga will do a beam test of it for us 
I’d wait for it to show up in a different flashlight.
I have an older M26C with XHP70.2 at 3000K. It does not have mode selection, is stuck with mode memory, has a defect in the lowest mode, and the light could be prettier. However, it wonderfully bathes the scenery with light and remains a favorite choice for both hiking the fields and forest edge at night and looking for critters in the dark.
I want to do that with a prettier emitter, high CRI, choice of mode group, and the ability to turn off memory mode.
I’d seriously recommend the FC40 in the M26C (especially add the green AR lens). It’s a great host for the LED
Anyone happen to know where I could get 3 or more pc of this LED 2700k in the USA? I kinda need them on the fly…
You might be better off posting a WTB post in the Buy/Sell category.
Mouser, Digikey,Newark.
None of those distributors carry Nichia products.
The Nichia website lists http://www.futurelightingsolutions.com/ as a USA distributor.
You can replace the driver and upgrade the emitter to a 70.3 HI high CRI.
I talked with Future Electronics and they only sell full reels from Nichia. That’s a purchase requirement of 1,600 LEDs in the case of the 719a.
So… Nichia LEDs are not well distributed, which is a shame.
Hey Nichia, sell your LEDs through Mouser and Digi-Key so we can buy cut tape singles. I need 80 LEDs, not 1600.
Curious to know what you need 80 LEDs for? 
What I really like about the 719A over a dedomed 519A or the new high-CRI SFT40s is that it forces the use of a boost driver in lights that might otherwise be linear or FET. There’s often a considerable improvement to efficiency as a result.
Indeed, and I like it for dual fuel drivers because it’s easier to make a high power 6V boost only driver than one that need to both step up and step down. There’s the XHP35 but NiMH to 12V is a bit less efficient, it has a larger LES and 719A has better tint consistency and tint shift.
