I've got an original Surefire E2 Executive incandecent light. The idea was to use it as an EDC handheld, but I always found it just a bit too large. Also, in today's world, It's every low on performance.
1. Is there an upgrade kit to make this worthwhile?
2. If not, what's the go-to?
I've got a Streamlight Micro-stream single-AAA unit that's ok as a utility light, but not bright enough for a weapon.
