Portable only matters if you actually keep the light on you. Powerful only matters if the output is usable after the turbo screenshot is over. That is the whole filter.
If you are shopping this category, start with three questions: what battery format are you willing to live with, how far do you actually need the beam to reach, and how much pocket space are you willing to spend? A compact 18650 or 21700 light usually solves more real problems than a giant novelty cannon.
If you want live examples, start in our EDC collection and compare them against the larger lights in all products. Candela, runtime, and carry size tell you more than generic adjectives ever will.
