The New Led Flood Light 150Watt is not a spotlight, a spotlight, a spotlight. Floodlights create a highly diffuse, non-directional light rather than a well-defined beam, resulting in soft and transparent shadows that fade much more slowly when used to illuminate objects than with spotlights, There are even floodlights that dim very slowly, looking like a light source that doesn't produce shadows. Spotlights, on the other hand, project a directional, well-defined beam of light that illuminates a specific area.
The traditional electric light source, whether it is an incandescent lamp or a high or low pressure gas discharge lamp, is composed of a glass bulb and a filament. Electric energy enters the bulb through the filament and is converted into light energy. The floodlight is by inductively coupling high-frequency electromagnetic energy into the bulb to ionize the gas in the bulb to form a plasma. Phosphors are excited by ultraviolet light to emit visible light.
