BACKUP LIGHTS: Was I all wrong about SecurityIng?

I tested the SecurityIng Backup Light to be the Best Backup Light of 2022 very recently. After my video, SecurityIng sent me another Backup Light that has the potential to become THE Best Backup Light in 2022 - so did it change my mind finally? Which one is now THE Best Backup Light for technical divers in 2022? I'll share my thoughts on the best backup light for your cave diving and technical diving needs. I explain what I think about the SecurityIng backup lights and why both might be the best backup lights for you, and provide a comprehensive review of the light.
