This video compares the Wuben X4 and X2 Pro flashlights, highlighting their similarities and differences in emitters, output, and user interface. The X4 features a rear tail switch for direct access and a larger 18650 battery, while the X2 Pro offers spot/flood switching and uses a more common 14500 battery. Both have a 1500 lumen max output and a 400 lumen side light, but accessory availability is a significant concern for both models.

This video explains the difference between lumens and candela for gun lights and handheld flashlights, featuring Andrew Wright from SureFire. Lumens measure overall light output, while candela measures peak beam intensity, indicating how far the beam reaches. The analogy of a garden hose illustrates how lumens are like water flow and candela is like the stream's reach with a nozzle. The video highlights that lumens and candela are not directly correlated and are influenced by LED emitter size and lens type. It contrasts two SureFire lights: the Stiletto (650 lumens, 1,500 candela) for broad illumination and the Scout Turbo gun light (650 lumens, 71,000 candela) for long-range reach, emphasizing that choosing a light should depend on its intended application to avoid issues like excessive reflection in home defense scenarios.
