Lume Cube advertises itself as the World's Most Versatile Light and is an easy light to add to your bag.

I've seen wedding photographers use these during receptions to help find focus.

Though a Lume Cube unquestionably provides you more control, I find a headlamp can be just an convenient and you can get creative with how you modify the light.

They aren't something I would use in studio but are an easy stash in your bag option.
