Flash Duration

Color Temperature

Consistent and Constant

The problem: With the rare exception of units costing many thousands of dollars, flash lighting packs, up to now, do not control the color temperature of the light. The color temperature typically decreases by over 100 degrees Kelvin for every f-stop of power reduction. Over a 6-stop adjustment range, this results in a color temperature decrease of over 600K. Even units that have a small 3- stop range can produce significant color shifts of over 300 degrees. This can result in much larger shifts between two light sources than film can correct. (Kodak recommends less than 200 degrees shift between light sources for their 5500-degree daylight film.)

The solution: Photogenic has created an affordable solution to this problem. The new Solaris PowerLights provide consistent and constant color temperature across their amazing 8-stop range. Be wary of claims of consistent color temperature at only one power level. This is not the same as constant-colortemperature over all power levels. Both are necessary to provide the perfect exposure we all strive for. The light produced by the new Solair is consistent & constant. Every time you key in a desired power level on the digital input, you will receive the same amount of light as you obtained previously, and at the same color temperature. The light produced by the new Solair is constant-color. No matter what power setting you select, the light will be the same color temperature. Using the standard color corrected flash lamp; every subject will be exposed to approximately 5400 degree Kelvin light, regardless of power setting. This solves forever the problem of unbalanced power settings in your studio, resulting in color temperature shifts in your pictures.

The Solair PowerLights provide motion-stopping capability ranging from 1/250- second flash duration at full power to 1/3700 at minimum power, eight stops down. Unlike shutter speed, flash duration can be reported in different ways. It is generally defined as the length of time light is produced above a certain power level. Photogenic Solair measurements are reported at the 1/10 power level or t = 0.1, instead of several other widely used methods.

While any point of the discharge curve can be utilized to measure the duration of a flash, the most commonly used are 1/10, 1/3, and 1/2 of peak. ‘Doc’ Edgerton [Edgerton, “Electronic Flash Strobe”, 1987, pg 30] recommended the 1/3-point be used for duration measurements in order to approximate the power being measured. While this has served the industry well for many years, the commonly available integrating power meter gives the exact amount of power delivered, and we no longer need to approximate this measurement.
