What flashlight enthusiast does not like to try out new emitters. Seems like the 519a offers more photons than a 219b, right?
On the Sky Lumen Lounge thread, I brought up having Vinh make a 519a P60 dropin for maximize throw, even though knowing it does not really offer a lot of push out there. Vinh only answered one of my questions, the one about using direct drive not being viable, and so I can't help wondering if the 519a is not suitable at all, throw-wise, compared with an SST-20 and does not offer that much of a gain in color rendering? Since being snubbed by Vinh, figure I can talk to Tod at Illumination Gear about EagTac using a 519a in a Sport Tac dropin. Years ago I communicated directly with EagTac, and they did build a custom emitter thrower for me. It did take a while to get to USA and they may not do that sort of thing anymore.
