A creature with a built in flashlight

I know things like flashlight fish exist; things with luminescence and all that. But how strong could the light be?

I have this cave dwelling species with three eyes except the middle one isn't exactly an eye but a place that can create a beam of light like a flashlight so the creature can see. It can be turned on/off and the intensity can be adjusted. This creature also comes above ground on occasion.
I thought about just giving it echolocation, but then the three eyes would not be as needed, and the three eyes thing is sort of linked to their triangular architecture and other culture things. How strong of a light can be created biologically, and how?

Or, would having three eyes still be realistic if it also has echolocation?

(Okay, this is a bit embarrassing, but not long after I posted this I realized that giving it a horn for the third point for a triangle themed face would solve all my problems so now my anxiety has flared up cause I asked for help I no longer need and took people's time for nothing)
