A question for the experienced hole hunters. What is the ideal brightness in lumens for a compact spearfishing light? Can a light be unnecessarily bright because it drains the batteries too fast? Is there an ideal balance between brightness and battery longevity?
For reference the Speardiver Spearfishing Flashlight in this video has 270 lumens.
