Constantly? Recharge and unplug.
Well, people nowadays tend to use phones everywhere while doin everything. Literally. I’m yet to hear anyone saying “sorry, I didn’t pick up the phone because I was near water and was afraid of dropping it”. Or anything close.
I’m not a fan of mule lights. Or extremely floody in general. And glare is the major reason. But then - I like powerful lights only. A powerful mule has serious glare issues. A phone light? I’m yet to feel bothered by one.
So recharge before it happens.
1000 lm/W is impossible for a flashlight as well and I fail to see how it’s relevant to the original statement.
But…no way, phones stand no chance against a good flashlight. The original opinion however was
So…for a certain group of people phone light is almost always good enough.
There was no statement of it being better. There was no statement of it replacing flashlights.
Though then - some time ago my mum asked me to find her an EDC light. After learning what she needed it for and what she used before I adviced her to use a phone light. And she’s happy with it. For her a phone light actually replaced a dedicated (but poor) flashlight.
