Beam angle basics
A bulb's difference in beam angles can produce different lighting effects in a room. They also have different functions. As observed in the following images, the first clothing store has a cozier and calmer atmosphere whereas the other exudes an energetic vibe.
The dimmer store uses narrow-beamed (spot) bulbs to create patches of light on the floor to direct their customer's path to the various clothing sections. They also used the narrow beams intentionally to create shadows for that cozy and calming feel.
The brighter store uses wide-angle (flood) downlights to create a uniformly lit environment. The lighting in this store is consistent throughout. Wide-angle lights spread the lights out further, hence covering more surface area.
As a result of a wider beam angle, the light distribution is less focused hence it is less intense compared to the narrower version. Therefore given the same wattage, the narrower version will always be slightly brighter at a targeted surface area.
