The AastroLight "Ring"

Features

• exquisite skin tones
• superb color rendition
• five colors + white LEDs
• Factory-preset color temperatures
• User-Programmable color mixture presets
• shadow-free ring lighting

AastroLight designs and manufactures full-spectrum LED illumination for precise skin tones and subject rendition - without using filters. Their unique approach to LED ring lighting, combining white LEDs with five additional colors, produces superior lighting with extensive control over color rendition. And as a ringlight, it produces shadow-free lighting without the need for additional fill light sources. A typical working distance for the Ringlight is from one to three meters and is perfect for on-camera talent as well as for product shots. The Ringlight can be mounted using an industry standard lens rail to many professional and prosumer video cameras. The Ringlight accepts DC power input from 8 to 12 Volts (9 to 11.1 Volts preferred) and from either external power sources (AC adapter included) or from the optional 11.1 Vdc Li-Po battery module.

Why 5 Colors?

By adding five additional colors to white LEDs, we have overcome the limitations of white-only LED lighting which produces poor color rendition when compared to full spectrum fluorescent, halogen or HMI light sources. White LEDs, by themselves, produce a noticeably inferior "white" light deficient in a number of wavelengths needed to produce pleasing skin tones and rich, saturated colors. By adding five different LED colors to white LEDs, we've greatly expanded the color gamut available to filmmakers and videographers. The light produced by this color mixture is dramatically superior to lighting using white-only LEDs, creating exquisite skin tones and dazzling colors. The difference can also be viewed as a graph using a spectro radiometer (see illustration) and the differences are apparent. An additional benefit to this design approach is independent control of each of the five colors to produce a wide range of color temperatures and effects without the use of lossy filters. Users can select between five different color temperatures and even adjust each color independently to produce precise color mixtures which can be saved as user presets to be called up later.
