I’m replacing my old-school Peak Eiger with something that will give better color (high CRI and neutral white), and started thinking maybe I’d try a CR123-based solution so it would share the same battery with all my other lights. I’m just not sure I want something that big dangling off my keychain. Is there anything besides the Peak Logan that’s small (for a 1xCR123 light), keychain friendly, and uses a Nichia 219?

My other thought is to ditch the battery requirement and go with something like the Quantum Ti. Still keychain friendly and using a Nichia 219, but trading size for battery life.

Any thoughts? Any other options? Thanks!
