I too had pretty much the same underwhelming opinion of the A2 at first and I am a professional pilot.
It took a lot of thought before I decided I wanted one, then I found a red LED 4 flat side that had been a display model for I guess 3 plus years back in December. I wasn't too impressed at first with the output of the LED's but then remembered the intent of the light, a low output LED for up close cockpit use to preserve night vision and a bright light for pre-flight . IMHO what we really need the LED part for in the cockpit is finding things we've dropped on a dark floor by our feet, reading 40 year old labels on the circuit breaker panel, that kinda thing. I have an overhead map light that points down into my lap to read charts that doesn't bother night vision.
So I took it on a trip. Still not impressed. I've got 3 overlapping ringy beams with small hotspots, it wasn't even very usable in the cockpit unless your eyes and the light were close to what you trying to see plus the Ican wasn't even very good for pre-flighting a small jet.
But there was something about the light. It is lightweight, very nice size, and if there is or ever was a better looking flashlight than a 4 flat-side A2, I haven't seen it! Plus I knew there were mods for it out there so I wasn't gonna give up yet.
Then came the Sportsman's Warehouse sale, too good of a deal to pass up so I bought another red A2 and left it in unopened for several days since I wasn't sure of why I needed 2 red LED A2's. (maybe trade bait for a blue one I thought).
Once it looked like there was gonna be someone picking the slack and making a drop-in replacement for the Aviatrix I decided to go ahead and open up the new one to compare, thinking I'll eventually mod this one and keep the 4 flat side original. (easier for me to justify modding a duplicate)
I was shocked at the difference in LED's, the new one is so much more floody, bright, no visible rings, more usable in a word.
I'll attempt beamshots tonight of both plus the Kroma to get people's opinion on a new thread.
That is all!
