Looking for 4000-5000K High CRI with large battery capacity

Anyway back to the D4SV2 I did find it with a 4500K 519A

You should also read about a 5700K 519A dedomed. It brings you to ~4000K but with a lower DUV.
Have you found this thread?

519A, Try Slicing!

I have several 519A emitters in various CCTs, all R9080. I’ve tried them domed: They are OK. I prefer my sliced 351Ds in most cases. With the dome they are very close to neutral duv. I prefer a negative duv (but not too negative!) There is some spectral shift over angle in a reflector. Not bad, but not anything special either. With the domed removed (very easy to do), I find the duv too low for my taste. The CCTs also drop too much as I prefer the 3500k to 5000k range (depending on flashlight …

And in this post is a picture leds in the color diagram

519A, Try Slicing!

First attempt at image, so I hope it works. 7 CCTs of 519A, all measurements with Opple (so just estimates, but numbers match what I see). Each with: dome on, 1.4mm slice, 1.2mm slice, 1.0mm slice, dedome Black = 5700k Blue = 5000k Red = 4500k Orange = 4000k Green = 3500k Purple = 3000k Olive = 2700k Round = with dome Square = 1.4mm Diamond = 1.2mm Trianlge = 1.0mm Upside down Triangle = dedome Also first time with ColorCalculator, so I didn’t know how to add a legend!
