When it comes to lighting for photography and videography, tungsten continuous lighting remains a popular choice, particularly for its warm tone and versatility. However, there are some important considerations to keep in mind, especially regarding heat generation and maintenance. Let’s dive into the specifics of tungsten lighting, including the nuances of fresnel and open face lights, such as redhead and yellowhead models.
Heat Generation in Tungsten Lighting
Tungsten lights, especially higher wattage models, generate a considerable amount of heat. This is an inherent characteristic of incandescent bulbs, where a significant portion of energy is emitted as heat. When using these lights, it’s crucial to be aware of this aspect to avoid discomfort and potential hazards in your shooting environment.
First Use: The ‘Burning In’ Phase
On their first use, new tungsten lights can sometimes emit smoke and an odor. This phenomenon is perfectly normal and is often referred to as the “burning in” process. During this time, which can last between 30 to 40 minutes, the bulb and its components heat up, burning off any residual materials from manufacturing. Once this initial phase is over, you typically won’t encounter any further smoking or odors.
Troubleshooting Smoke and Odors
If you notice smoking after the initial burning-in period, this is often due to dust that has settled on the lamp or oils transferred from your fingers when adjusting the light or its barn doors. In most cases, this should burn off quickly and only last for a few minutes.
Important Tips for Handling Tungsten Lights
Keep Your Bulbs Clean
To minimize unwanted smoke, ensure that your lights are kept clean and free from dust. Regular maintenance can help prolong the lifespan of your bulbs and improve performance.
Avoid Direct Contact
Top Tip: Never touch a tungsten bulb with your bare hands when installing it. The natural oils and grease from your fingers can significantly reduce the bulb's lifespan and increase the likelihood of it breaking. Always use a clean cloth or gloves when handling bulbs to ensure they remain in optimal condition.
Conclusion
Tungsten continuous lighting can be a fantastic addition to your lighting toolkit, offering warmth and versatility for various shooting scenarios. By understanding the heat generation, the burning-in process, and proper handling techniques, you can maximize the performance of your lights while ensuring a safe shooting environment. With these insights, you’ll be better prepared to harness the full potential of tungsten lighting in your photography and videography projects. Happy shooting!
