Yup. Via a PC connection to the Petzl software, the Core can be set to regulated/unregulated and the two white levels can be set by percentage of maximum output/time of operation. What's more, you can save multiple configurations by name and by headlamp model (among the models the Core connects to). One could have summer, winter and trail running profiles, as random examples. I reduce the giant gap between default low and high.

Red LED mode isn't programmable, but I don't miss the option.

I confess I like the whizbang nerdy appeal of the thing. I'll add that with NiMH and lithium cells, the Tikka acts like it's regulated, even though it's not. Not the case with alkalines, though.

Cheers,
