Introduction to Infinity Lighting
Dedo Weigert, an expert in the field of lighting, has introduced an innovative concept called ‘Infinity Lighting’. This method aims to create the illusion of natural light emanating from a far distance, challenging traditional lighting principles such as the Inverse Square Law.
The Concept Behind Infinity Lighting
Infinity Lighting seeks to produce an organic quality of light while counteracting the Inverse Square Law. This law states that as the distance from a light source increases, the intensity of the light decreases. Specifically, doubling the distance results in a light intensity that is a quarter of the original. To overcome this, dedolight has developed unique products that defy this principle.
The PB70: A Unique Lighting Solution
One of the standout products in the Infinity Lighting lineup is the PB70. This light not only has a distinctive appearance but also boasts high output and low power consumption. The DPB70, a variant of this light, produces a parallel 2° beam from its 70cm (2.3′) front diameter. It excels in efficiency and homogeneity within the beam, particularly past 10 feet. These qualities are essential for the Lightstream reflectors system.
Technical Specifications and Performance
The DPB70 includes several advanced features:
- High Output: At a distance of 15 feet, the light meters around 112,000 lux and illuminates a 34-inch diameter circle.
- Hot Re-Strike Capability: It features DEB1200D flicker-free, DMX-ready electronic ballast.
- Extended Dimming Range: The light can dim from 100% to 60%.
- Robust Construction: It is IP63 rated, making it suitable for indoor and outdoor use, even in mild rain.
Defying the Inverse Square Law
The PB70’s performance challenges the Inverse Square Law. At a distance of 5 meters (16.4 feet), it produces 112,000 lux. Traditionally, doubling this distance would reduce the light to 27,000 lux. However, the PB70 outputs 68,000 lux at 10 meters (32.8 feet). This discrepancy is due to the light’s parabolic construction, which creates an intense parallel beam from a virtual light source located behind the light head.
Practical Benefits
The most significant advantage of this technology is the minimal exposure change when subjects move towards or away from the light. Traditional lighting can cause drastic exposure shifts, especially when actors move closer to windows. The PB70 mitigates this issue, providing consistent light levels and reducing the need for large lighting setups.
Versatility in Tight Spaces
The DPB70’s design allows for efficient use in confined spaces. By placing a large Lightstream #1 reflector 3.3 meters (10 feet) from the DPB70, users can redirect the beam through a window, mimicking shafts of sunlight in a compact space. This setup traditionally requires large HMIs and a Condor from a significant distance. The DPB70, however, operates on a regular house breaker, eliminating the need for a generator.
Simulating Daylight and Sunlight
The PB70 is exceptional in simulating natural daylight and sunlight. Its parallel beam, when reflected, extends the light path, providing an authentic sunlight effect. This capability is particularly valuable for creating realistic outdoor lighting scenarios indoors.
Cost and Accessibility
While the PB70 is a powerful tool, it is not typically aimed at owner/operators due to its size, weight, and cost of $21,500 USD. However, dedolight offers smaller fixtures with parallel beam attachments for those looking to achieve similar effects on a smaller scale.
Conclusion
Dedolight’s Infinity Lighting, exemplified by the PB70, represents a leap forward in lighting technology. By defying the Inverse Square Law and creating consistent, high-quality light, it offers photographers and filmmakers new creative possibilities. While it comes with a hefty price tag, the innovative design and performance make it a valuable asset for professional lighting setups.
