Most cards aren't white. I'd suggest a WhiBal card, which works fantastically for me. Though, you really need access to the light. If you stick the card on a colored bench, the WB reading will include that color cast. Also, include it in your scene as a reference just in case the WB goes wrong and you need to correct in Post.
Another issue may be shutter speed with cyclical lighting. With video, you generally don't have to worry about this as the shutter speed is usually 1/60 of a second. However, with my DSLR, I noticed that I have to set the shutter speed to 1/30 to make sure to average a couple of cycles as my DSLR uses only one image for the WB. Does the EX1 use more than one frameof data for the WB? I'm also wondering if the rolling shutter could affect WB as different parts of the image will be illluminated by the various phases of the light cycle.
