One of the tools I recently acquired is the Festool SysLite KAL-2.
It’s just a battery and LED light. But it’s made such a huge difference in my work. I have headlamps, flashlights, all sorts of stuff. But just being able to stash a light somewhere has been a gamechanger.
It’s really hard to show in a picture how much light it throws, but it’s pretty amazing. On top of that, it can use batteries from other Festool cordless tools I already have.
It really is a pretty amazing item.
