The OrcaTorch D530V red is a professional diving light with a 120° beam angle. It comes with an 18650 3400mAh USB-C rechargeable battery. Why do we need a red diving light for underwater photography? Many marine species can not see the color red. Using white dive light scares the nocturnal creatures. They will try to hide or flee from the illuminated area. Red diving light does not disrupt the darkness in their eyes. It allows you to get closer to them.
