Some advice needed, please. I want to mod a Surefire E1B with either one of the 219C sm503 or 219B sm453. Would you prefer the 219C with H17F and the possibility to direct drive it with 8A AW batteries? Or stay reasonable with the 219B with a linear 1.4A driver? Max output vs. max color rendition?
I am not yet sure what to do. Thanks for your input!
Both are great options. For a single LED setup I prefer the 219C simply due to the extra output it offers. But then I like having at least 700-800 lumens on tap in regulated modes of 2.5-3A.
For a triple setup I will know more later, building a triple 219B 9080 to see what it does later today most likely.
Well, had it all together and bench tested it as working but when used with a battery it shorted out and something is shorted to ground now. Not sure what but gonna have to take it apart to figure it out. Not sure when I will get time to do that.
It looked good during bench testing though, I think the LEDās are ok, just the driver if anything. I was using a driver out of my parts bin so not sure what the issue is.
Djozz, thatās exactly what I had in mind. Should be very nice with Carclo 10511 for example.
@Everyone, FYI, djozz tested the predecessor of the NCSL219B-V1 in a low CRI version, the NCSL219B. Compared to the XP-E2 R3 thatās a pretty impressive performance, if you ask me.
I would love for Nichia to really take a liking to our world, there are a few holes in the LED world that are waiting to be filled.
I would love to see a quad 219C die LED on a 5050 XM-L footprint with every possible effort put into heat sinking, no worries about how big or tall the LED is. Make it a domeless LED with only a thin coating of silicone to protect the die as well. Then put all the dies as close together as possible and wire them in parallel thus allowing us to run it off a single cell.
Done properly it should be capable of 2000+ lumens on a normal star and over 4000 lumens on a DTP copper star. It would cost more then normal but it would be WELLL worth the cost for flashlight guys.
A simpler emitter that would be great to see would simply be a domeless 219C optimized for throw.
Also putting the phosphor from the 219b 9080 onto a 219C die, The 219C handles the heat WAY better then the 219B so it would allow for more output when driven hard I assume.
I am Interested in 7-10 pieces of NCSL219B-V1 R9080.
But I am more interested in the ānormalā NVSL219B-V1 R9080 or Better a 219C R9080.
If the NVSL would be aviable too, I would only take 3-5 of NCSL219B-V1 R9080.
