Simon, any chance you would stock 519A in 5000K (or other temperatures) in the future?
Some modders reported very good results slicing the 519A, which has the side effect of lowering the temperature. Thus, to start with a 5000K emitter should give an end result of about 4500K, which is desirable for many.
If the 519As become available in the S2+ (and other lights) in a range of colour temperatures from 2700k to 6500k, I can see myself buying quite a few for night photography (replacing my LH351Ds).
Simon, did you ever get a round to do some measurements? If not, I’m assuming you’re enjoying a well deserved vacation

Would love to have a high CRI alternative to the LH351D in various temperatures. Already have too many LH351Ds and I’m done with SST-20, which is too narrow beam and only 2700 and 4000K (low CRI of colder ones is a no go).
I remember when Simon released the driver first red W1 Osram, and iirc it was made more so for the lower voltage frequency of that LED not necessarily the low amps.
Couldn't a red W2 be used with 8*7135 more efficiently? I have used a couple, but I've never looked up what they're Vf is.
By the way today I burn out my FC-40 driver today when tried to put it from M21C to new kaidomain host. Most interesting of that driver is that it is based of MP3431 boost driver IC which is very good. Most of Convoy 6V driver for XHP70.2 and XHP50.2 are TPS61088 based.
Speaking of drivers, when cleaning contact surfaces in a B35AM light, I found that the driver contains an IC with the identification sanded off. Not what I expected to find in a Convoy light and I wasn’t looking for it either. It just stood out due to the roomlight reflecting differently, so it peeked my interest.
Then don’t sand it so it doesn’t look different from the rest! It’s the good old if somebody tells you not to do something, you really want to do exactly that I know you know the feeling
