Not really. The domed 519A beats the 719A in output: Nichia 719A 5000K R9050 tested - #6 by thefreeman
Given the low dedome loss for the 519A, the dedomed 519A will be comparable to the 719A in output; in fact, if one compares emitters with the same dedomed CCT, I would not be surprised if the dedomed 519A is still higher, despite being 9080 instead of the 719A’s 9050. Given the difference in R9, it is pretty clear that the 719A has lower efficiency.
Lower efficiency, lower CRI, weird Vf…I don’t see the appeal of the 719A at all.
