I love the clean and perfectly useful Sappire light for my keychain, but, I occasionally need a bit more output, so Often I regrettably leave my sapphire at home in favor of a light like the Preon 1, is there any chance of a multi-mode sapphire light? Something with a bit more output?
I think a multi-level driver that could fit in a Sapphire would have to be made of multiple circuit boards sandwiched together, because there's barely room for the components that are already present.
