Blue Beams & Burn Time: HID Lighting Deep Dive with Barry Miller

In this episode, we head into the Salvo Diving workshop with Barry Miller for a masterclass on underwater lighting. Barry breaks down exactly how HID (High Intensity Discharge) lights work, why tech divers love their color temperature and insane burn times, and how ballasts, bulbs, and battery chemistry (lead acid, NiMH, lithium-ion) all fit into the equation. If you've ever wondered why a 10W HID can out-perform old 50W halogens—or what "5600K" really means underwater—this is your geeky, glowing deep dive into dive lights.
