I have some of everything but if you told me I could only have one light it would be my Lucifer headlamp. I can work on things…check the dogs at night…walk/run with it (no running for me) and It even has a mount for my bicycle! Whats not to like??? Far superior to flashlights IMO.Okay, maybe they're not completely useless... but in the majority of uses, I'm finding lanterns and flashlights with diffusers to be far more useful and practical than flashlights. Of course, YMMV.
The only thing I find myself using a flashlight regularly for is inspecting aircraft or looking for dropped screws
Otherwise, it's a lantern of some sort for me. Even post-flight, I'm usually magnetically-sticking the tail of an EDC18 with diffuser on the speaker grille. Repairing engines? magnetic lantern. Repairing HVAC? magnetic lantern. Night-light in a foreign hotel? Lantern. Power outage? Lantern. Changing a tire? Lantern.
Don't get me wrong, I enjoy playing with fire-breathing, pocket-burning monsters...but practically, they're shelf queens here.
