High-Tech Lighting for High-Tech Imaging
K-Lite mounted on Pole Stand. Barn Doors installed
K-Lite with MP/4 copy stand. Transparency Kit and Precision Mount installed
The K-Lite is an intense, diffuse, flicker-free compact fluorescent light source featuring excellent color rendition. The K-Lite is ideally suited for both reflective and transmissive subject high resolution electronic image scanning. The significantly reduced infrared content of the K-Lite (compared to conventional incandescent light sources) allows photography of sensitive subjects with correspondingly less heat damage.
The K-Lite was developed jointly by photographic and electronic specialists to fulfill lighting requirements of the new long shutter duration electronic scanning cameras. The solution that evolved was a highly efficient, state-of-the-art fluorescent light source that meets the special requirements of video and digital photography while remaining long-term cost effective.
Output Intensity: 23,200 Lumen.
Corrolated Color Temperature (CCT): 5,000 Kelvin (2700K, 3000K, 3500K, 4100K color temperature lamps are also available).
Frequency of Energization: 27 kHz nominal (flicker-free for electronic imaging).
Color Rendering Index (CRI): 98 (5000K lamps installed).
Light Meter Reading (ASA100,1/60th): F11 measured at 50cm (20 in.), (similar to a 1000W tungsten light source).
Spectral Power Distribution Graph:
Lumen Maintenance Graph:
Power Requirements: 120 VAC, 350 Watts (3m (9ft.) power cord standard).
Light Source: An array of eight 39W OSRAM DULUX®L Trichrome Phosphor, compact fluorescent lamps.
Lamp Life: Up to 20,000 hours, under optimum conditions, see Relamping.
Ballast: Quality American manufactured units featuring electronically regulated lamp energization, reduced harmonic distortion for prevention of interference with sensitive electronic scanning systems, and a five-year manufacturer's warranty.
Reflective Subject Mounting: Standard Bogen 5/8M rapidaptor on angle adjustable/lockable yoke suitable for Bogen light stand or Super Boom (not supplied). Barn Door kit supplied as standard accessory.
Transmissive Subject Mounting: The transparency kit, consisting of mounts, a 38 X 43cm (15 X 17in.) diffuser and diffuser shields with apertures of 6 X 6 in. and 9 X 11 in., is available as an optional accessory. Diffuser shields may be fitted with precision transparency mounts (not supplied) when registration or repeatability is critical.
Construction: Built in the U.S.A. of high quality, low reflective painted aluminum, with special attention to weight and strength. Design allows simple change-over to accommodate mounting and lighting options.
Dimensions: (Base Unit Only, no accessories installed)
Height: 45cm (18.0in)
Width: 41cm (16.0in)
Depth: 13cm (5.0in.)
Weight: 7kg (15lbs.)
Thermal: Due to the high efficiency of both the solid-state ballasts and the OSRAM DULUX®L Lamps, the K-Lite case temperature never exceeds a touchable level. Other than allowing an unblocked air-flow to the unit, no special provisions are required.
Operating Positions / Photometric Stability: Universal. When mounted vertically, OSRAM recommends a lamp-base up position for optimal photometric stability. Stability is achieved after ten minutes of operation without changing unit position.
Illumination Pattern and Intensity Graphic:
ASA 100, shutter 1/60sec
Readings after ten minute stabilization
Relamping is recommended after 12,000 hours (more than 90% of lamps survive at 90% lumen output).
Safety: Constructed of UL listed electrical components.
