Sunwayman V11r
w sw30 220 lumens
w sw45k 270 lumens
w 2700K LH351D 365 Lumens
w 4500k 519a 420 lumens
(btw the minimum w 519a is 0.01 lumens, lowest Ive seen on a V11r)
.
in V11r beam is worse w 519a than LH351d, but 519a beam is better than sw45k
.
Tint of 519a is much greener than sw45k (true for most LEDs):

imo, the 519a is not as good a match for the V11r reflector, as the LH351d.
I dislike the Tint shift of the 519a, it has a green corona.
For people wanting higher Lumens and neutral Tint DUV, the 519a has higher output than LH351d.
Overall, my first impression of the 519a 4500k (mine came from Convoy Simon), is that it is not an LED that I would want to use again, due to tint shift (fixable with a pebble Tir), and not low enough DUV for my personal preference.
fwiw, I got a DUV of –0.0018 on maximum output (~400 lumens)… the DUV of –0.0003 was at 15 lumens
— for reference, here is the same light when it had LH351d 2700k mod
and some other V11r pics w 219b mods:

I found the greenest LED I have… now the 519a does not look so green:

Tint perception changes based on the Tint of other lights it is compared to.
Ultimately, each of us has to try different LEDs for ourselves, to form our own impressions.
