What type of lamp diffuses light and is used when a soft light effect is needed?

A frosted lamp is specifically designed to diffuse light, creating a softer and more even illumination. The frosted coating on the lamp's surface scatters the light as it passes through, minimizing harsh shadows and glare that can occur with clear bulbs. This quality makes frosted lamps particularly effective in settings where a gentle and warm ambience is desired, such as in residential lighting or theatrical productions. In contrast, while incandescent lamps can provide warm light, they typically do not have the same level of diffusion unless they are frosted. LED and fluorescent lamps also provide light but often do not achieve the same soft, diffused effect as a frosted lamp without additional diffusion materials. Thus, a frosted lamp is the ideal choice when the goal is to achieve a soft light effect.
