Hey Hank , stop teasing us, first you get us exited by saying you’ll be making a D7 & then tell us it’s a no go , then this D1s+ which is also not gonna happen.
Please don’t tease us anymore ,in future please keep new developments to yerself until it’s up & ready & gonna be for sale.
This isn’t a negative whine because I highly rate your lights & consider them at the top of the pile & I can’t wait for more new ones but I get so disappointed when I think the next best thing is coming & find out it’s not.
Hmm… The D1S is begging for an LED like the White Flat 1mm², and it would definitely sell.
But the White Flat 1mm² is begging for a current regulated driver, which is not (yet) available for Emisar.
But the trend in LED land is low Vf, so it’s time for Emisar to get a current regulated driver available.
It shouldn’t be that much more expensive than the DD driver i.m.o.
And it will open the door to more choice in emitters, like Nichia 219B V1 for the quads, without risking their lives.
The electrical path can be optimized as far as you wish, and you can use the highest drain cells.
Longer run times in the highest modes without immediately losing output.
Come on Hank, get some proper drivers for your sweet little lights.
I might even buy one !
It depends on what you want from the driver. If you want the best, most efficient driver, get a L4P driver tuned to the proper current. If you just want it to be “regulated” and have a decent UI, you should get a driver that uses AMC7135 chips for power, PWM for lower modes, and Anduril firmware.
My mini-GT driver seems to have lost the 7135 part of the ramping after I tried the 2mm2 White Flat (it is still gone with the new led, a dedomed XP-G2). It seems to make little sense if the White Flat with its low voltage was the cause of the damage, but after what you noticed with the NANJG driver I tought it’d be relevant to mention here.
Good to hear, I did not wish to cause panic, was just sharing my observation, the damaging of the mini-GT driver may not have anything to do with the 2mm white flat.
He should just use one of these. Is it really $10 stopping it or is there an issue with driver size and the D1S. He is hopefully redesigingim it a bit for a 21700 anyway.
Thank you Hank for an update. It’s sad to learn you can’t do it, but I like your openness.
I suggest that you look at Texas Commander driver. It’s in a beta state. And may not deliver the current that you need. But using Led4Power trick of putting the FET on MCPCB should solve the issue and make it easily handle 5A, probably 8A for 2mm² variant as well. You would still have to put the work of taking it out of beta and into production…but it seems you’re more than capable of doing so.
