One-K is a term often used in theatrical and film lighting , and refers to a specific type of bulb with an output of 1,000 watts . The term comes from the abbreviation "K" , which stands for "kilo" (1000 in the metric system), so a One-K bulb is a bulb with an output of 1,000 watts .
1. Types of One-K lamps
One-K lamps are often used in theatre, film and television studios for lighting applications that require high light output .
| Lamp Type | Description |
|---|---|
| One-K Fresnel | A type of Fresnel lamp with a power of 1,000 watts. This is widely used in theaters and film sets for diffuse lighting . |
| One-K PAR | A Parabolic Aluminized Reflector (PAR) lamp with 1,000 watts of power. Often used in direct lighting applications . |
| One-K Halogen | A 1,000-watt halogen lamp, often used for bright, warm lighting in films and theatre. |
📌 The choice of a One-K lamp is determined by the required light intensity and the type of lighting.
2. Using One-K lamps
| Application | Why One-K? |
|---|---|
| 🎭 Theater lighting | One-K lamps are used for general lighting or for spotlights that require strong illumination. |
| 🎥 Film sets | They provide powerful lighting for backgrounds , close-ups , and ambient effects . |
| 📺 Studio lighting | One-K lamps help create the right light intensity for film shoots in studios. |
| 🏢 Events and shows | One-K lamps are also used for large events , such as concerts and trade fairs , where a lot of light is required. |
📌 The use of One-K lamps is often found in situations where clear illumination and high light intensity are required.
3. Benefits of One-K lamps
