I hear you Leigh. I just stepped outside and took some readings with my Minolta Color meter II. I got between 5200 and 6000 depending where I pointed it (It's sunny with no clouds today here). My meter is the older version that requires the incident sensor head to be swapped with the flash sensor head for flash readings. I was just surprised that my speedotron 102 flash heads were so far away from 5500. The readings from the flash heads were quite consitent from burst to burst. I just sent email to speedotron to see what they think. My understanding is that these flash heads should measure closer to 5700K, and that the new UV coated bulbs are closer to 5500K.....
