Same here. More worried about blown bulbs than battery life. Advantages in throw & colour rendering will eventually be overcome. The only lasting advantage I can see is that bulbs don't overheat like LEDs do. That is useful in things like searchlights or certain military/industrial applications, where HIDs are still currently used, although usually connected to mains power or a vehicle powerplant. LEP matches or exceeds the throw of HIDs & don't face overheating problems due to comparatively low lumen outputs, but they do not match the field of view as the beam is very narrow with next to no spill.
Of course there's also the issue with dimming. You can get lower output on a incan light by simply dimming the bulb but that will also decrease the CCT. There's no good consistent way to archive multi-mode incans apart from using multiple bulbs, like the Surefire 9N for example.
I love incans, but realistically LEDs are simply far more versatile, durable & long lasting. I don't see incan bulbs having any real world advantage that would be significant to the average civilian user, apart from nostalgia. The incan I use most is a modified 3C mag running a conservative 10W halogen on 2x 21700s. I got dozens of those bulbs so Im not too concerned for now.
