New Puck.js production run

They're all Kingbright - APT1608LSECKJ3RV, APT1608LZGCK and APT1608LVBCD. The idea is they're better at low currents like ~2mA - since you shouldn't be drawing loads of power out of the CR2032

Wow, those are very efficient! I'll see if I can find something comparable in RGB that's thin and diffused.

I've noticed the silicone picks up dust too - I'm not sure there's much that can be done about that. At least if I were to sell tinted black covers then it would be less obvious :)

I'd just try washing the silicone cover with some hand soap. Tinted covers might reduce LED brightness further, of course.
