Driver like this one with usb probably doesnt exist right?
What host are you looking to put it in?
FW3A 519A 3500K
ā¢ Attiny 1616 adapter
ā¢ RGB Lume1 board
ā¢ Swap 0402 resitors to 1.8K for blu, red and 5.6K for green

L70 Hi in a convoy Z1, just with the 6a 12 group driver for now until more 3v8a bucks come in the mail.
I get round emitters in zoomies now. Iām in love with this thing. Positive DUV and all.
I need to sand down the gasket more, get it as flush as possible with that not-reflective reflector thing, hopefully get rid of that spill. Still a work in progress

That looks great. Iāve been meaning to pickup the Z1. My only zoomie experience is the ol sk68. Iām sure this is leaps and bounds over that one.

You could use the 12A driver and get a tiny bit more power too
Its tempting. My 8a drivers could be weeks awayā¦I canāt believe the intensity just with the 6amp driver. This beats an sft40 maxed out to my eye. Theres just so little info on them. Do we know that it has similar Vf to a yinding? I assume it does, but idk. Theyāre so delicate when youre handling and reflowing them too. But it does feel like it has a little more to give.
Not sure but it is a well made host. Really well made. Itās still a zoomie, with all the typical zoomie issues. I ordered mine with a 519a, because I bought it to swap the emitter and the 519a was the cheapest one. When it came in I thought, āwow, this is really niceā. Then I actually used it and thought, āwow, this is really stupidā lol
But with the L70 hi, and Iām sure with similar emitters, itās really fun and actually usable. Iām getting a second one for sure.
In retrospect I shouldāve asked Simon what driver the sft40/culpm1 version comes with, because if it comes with the 8a buck it wouldāve been worth it to order one of those instead, and based on the price difference it probably does. But it doesnāt say anything in the listing. I didnāt think about it at the time.
Sunwaman M11r Elfin, replaced XM-L2 with Domed 519a 5700K. This is the lowest DUV I have ever seen for any Domed 519a:

Guys Iāve been looking at my Astrolux FT03 and itās feeling a bit outdated with the SST40.
I need suggestions for a swap.
Thought about the SFT-40 but already have a L21B with it.
Iām thinking on swapping a XHP50.3 HI 3v.
Anybody knows how it handles the FET driver and what output can I expect?
2 Thanks
Kind of a lateral move imo.
Lots of videos comparing the two. Hereās one that i didnāt watch but looks ok. Probably using the 6v version though. But thereās lots of others out there.
The xhp50.3 will have a nicer tint. The sst40 will probably have less shift. Output will probably be pretty close, depending on the bin. A lot of it will probably come down to the bin, the CCT, and how high a CRI you go
You could get the new 5000k sft40
Well. Thatās something different at least. I am waiting on the 3000k version. I could go for a SFT-40 3000k if it doesnāt take too long to release it.
Ya, Iām waiting on 3000k too. Kind of pricey just to get a slightly warmer and maybe greener version in the 5000k right now.
The 50.3 hi will have a nicer tint for sure especially if you have one of the really green SST40s. But idk. Itās not like itās Nichia level tint
Try the osram culp, is similar to sft40 but a little bit of spot
I have a m21c with a dedomed 2700k 519a. Itās just gorgeous beyond imaginationā¦ not very powerful though.
Iām yet to buy this emitter. But i feel itās made for smaller lights. Otherwise the beam is so thin that becomes unusable.
I want to try it in a S2+ or something like this.
8 amps are not for smaller light in my opinion. In alternative try SBT90 or Ynding 3000k
Would the sbt90.2 be ok with the stock FET driver of the light?
Installed a dedomed 2700K 519a w pebbled tir into Sofirn SC21 Mini. This light is available for adoption.

Yes but you have to change led pcb
