Hi, here are the details: Mode 1: 1100-250 lumens, runtime is 2+85 minutes; Mode 2: 250 lumens, runtime is 100 minutes; Mode 3: 60 lumens, runtime is 7 hours; Mode 4: 15 lumens, runtime is 26 hours; Mode 5: 2 lumens, runtime is 10 days. For red light, the output is 40 lumens, runtime is 150 minutes. Thank you.

does it have removeable a battery?

Hi, yes the battery is removeable. Thank you.

Can it be used with CR123a batteries as a backup ?

I was told by a representative from OLight that the Prerun 2 is NOT compatible with CR123a batteries. This is why I'll be returning mine. I want my flashlights to be standards-based and custom batteries are a no go.

What color tint are the non-black lights?

They are cool. Only the black has the 2 options of cool and neutral. I’m trying to figure out which one to get.
