Here’s a few rough estimates at 5A based on Maukka’s data for 95 CRI versions, assuming 90% optical transmission:
2000K - 900 lumens
3000K - 1200 lumens
4000K - 1300 lumens
6500K - 1400 lumens
7A gets about 30% more. I’m a little concerned about how close it would get to the 10-11A peaks that Texas Ace and Clemence saw in their bench tests, which had better cooling than a flashlight.
I know the ability to go higher when desired is always wanted, but I’m excited that there’s even a 5A E21A configuration on its way.
