I wrote Aqua Illumination the following regarding the Sol Super Blue: Would there be a possibility, as I don't have the equipment to do so, to test the Kelvin settings so we could use a pre determined % to get the desired look that users desire? I know it boils down to preference, but knowing where to start would be beneficial for those of us who aren't really inclined in this knowledge. There response was: At this time we do not have a chart available to set the color temperature. This is largely due to the abundance of blue within the Sol spectrum, as it goes beyond the black body scale (color temperature). White alone is 6000-7000K. As you add blue and royal blue, the value increases. Best regards, Has anybody done this research? It would be very beneficial for those who like "kelvin ratings", but don't know where to start to achieve them.
