I just got my Acebeam Tac AA with a 5000K 519A yesterday and an Eagtac D25AAA with a 5700K 519A today.
I was drawn to the Tac AA by the beamshots I've seen online and man, for a AA/14500 light with a 519A, this thing throws a pretty good distance. I can imagine the other LED option would be one hell of a pocket rocket! It's a bit on the longer side and I see a lot of people complaining about that, "it might as well be 18650" but it'd be even longer with the same reflector setup and much heavier. As is, it's actually pretty lightweight and feels great in the hand. I'm not crazy about having 4 modes with mode memory however, especially on a "tactical" light. I think either a programmable model or just a 2 mode version would be an absolute knockout, but as is, it's still a decent light with an amazing beam.
Eagletac used to be my favorite brand, but they've kind of fallen off the map to/with the community. I check them out every now and then to see if anything catches my interest. I came across a light that caught my interest and in doing some research learned that you can message Eagtac on Ali and request another LED. Being my indecisive self, I couldn't decide what LED I wanted. CPF logic says buy them both, but that's a bit more than I wanted to spend, so I ordered 2 different, but cheaper lights to see how I like the LEDs from Eagtac's supplier.
The first light I got was the D25AAA with a 5700K 519A. I kind of always wanted to get one of these a long time ago, but never did. In all honesty, it's nowhere near the brightest AAA light at 79 lumens nor is it the dimmest or longest running at about 6 lumens for 6 hours, but I honestly am liking it so far. The 5700K 519A is absolutely beautiful and pairs nicely with the light's optic, which is pretty comparable to the Sofirn's C01S optic, but a larger hotspot due to the 519A. The pocket clip is pretty nice too and has a decent magnet in the tailcap, but I suspect the tail might be glued, not that that bothers me. It is also 10440 capable, but it has to be a button top cell, which I don't have. I'll probably try a runtime test on low to see if it performs any better than advertised.
