A PAR38 bulb is a type of light bulb. The term “PAR” stands for “parabolic aluminized reflector,” which refers to the shape and design of the bulb. PAR bulbs, including the PAR38, use a parabolic reflector to control and direct the light output in a specific direction. The “38” in PAR38 indicates the diameter of the bulb in eighths of an inch, which translates to a diameter of 4.75 inches. This larger size makes PAR38 bulbs suitable for applications that require a focused, concentrated beam of light. They are often used in track lighting, recessed lighting, and outdoor floodlights. PAR38 bulbs are available in various technologies, including incandescent, halogen, HID, and LED. LED PAR38 bulbs have gained popularity due to their energy efficiency, long lifespan, and versatility. They are known for their ability to produce a bright, directional beam of light, making them ideal for highlighting specific areas or objects.

什麼是 PAR38 燈泡

PAR38 燈泡是一種照明燈泡。「PAR」代表「拋物面反射聚光燈」（parabolic aluminized reflector），指的是該燈泡的外形與設計。包括 PAR38 在內的 PAR 燈泡皆利用拋物面反射鏡來控制並指向特定方向的光線輸出。PAR38 中的「38」代表燈泡直徑為八分之三十八吋，即直徑等於 4.75 吋。較大的尺寸使 PAR38 燈泡非常適合用於需要集中光束的場合。它們常用於軌道燈、筒燈（嵌入式燈具）以及戶外投光燈。PAR38 燈泡提供多種技術選擇，包括白熾燈、鹵素燈、高強度氣體放電燈（HID）及 LED。其中 LED PAR38 燈泡因具備高能源效益、長壽命與多功能性而大受歡迎。它們以能產生明亮的方向性光束著稱，是突出特定區域或物件的理想選擇。
