Will there be a 4000k version NON ROSY positive duv yellowish version of this led?

The Firefly 3700k 351a would come closest, but I have no experience with it. Simon’s XHP70.3 R70 4000k is another candidate. It is less expensive and has great brightness, around 3000 lm. I posted about it on this thread HERE.
