Fotodiox’s Pro High-Intensity Studio LED studio light is available in two versions including a Tungsten or the Daylight model I used for this shot. Both produce output of 7600 Lux/m or 600 foot-candles and have a CRI (Color Rendering Index) of 85. Fotodiox claims it produces the equivalent to a 600-Watt incandescent source and the output is dimmable from 0-100%.
I used a Gossen Luna-Star F2 meter set at ISO 100 to measure the Daylight model’s maximum output at ten-feet producing an exposure of 1/15 sec at f/2.8.9. I used a pocket spectrascope to analyze the quality of Fotodiox LED’s and found a smoothly reproduced spectrum with no spikes or missing color bands.
The light’s built-in glass diffuser produces soft, even lighting and a rear-mounted fan prevents heat build-up allowing comfortable and longer sessions for subject and photographer. I usually complain about the noise studio light fans produce but this one quietly does its job. The Pro High-Intensity LED light comes with a removable 12-inch Reflector that has a white interior along with a diffusion sock that can be attached to the front of the reflector to soften the light. It has a Bowens S-compatible mount for attaching accessories such as soft boxes, barndoors, and snoots.
Following the basic lighting guidelines that a big, diffuse light source being placed close to the subject creates the softest possible light, I used the Fotodiox LED studio light with a 47-inch Glow Grand Softbox mounted (see above) to photograph Pam Simpson against a black Savage Infinity vinyl background. A Westcott Scrim Jim was used as a reflector at camera right. Camera was a Panasonic Lumix G5 with 14-42mm kit lens (at 42mm.)
