Our party picked up a Lantern of Revealing:
While lit, this hooded lantern burns for 6 hours on 1 pint of oil, shedding bright light in a 30-foot radius and dim light for an additional 30 feet. Invisible creatures and objects are visible as long as they are in the lantern's bright light. You can use an action to lower the hood, reducing the light to dim light in a 5-foot radius.
Any reason we couldn't just forgo the oil and use a light cantrip?
I tend to think "no", because of meta-game thinking (Why the heck would it require oil if the damn thing is magical in the first place?) - but 'yes' because it has the exact same stats as a regular hooded lantern.
