I use a variety of ways to correct for WB including setting manually with a white card, expodisc and grayscale. I can do it before or afterwards in the raw editor, still LEDs are not one of the light sources recognized by the cameras two WB sensors or software and getting the bright white LEDs to come out accurately is a pain. In all of my efforts they came out much bluer than in reality. Usually my pro gear has no issues with color reproduction in interior shoots and portraits with or without flash. It's when the AWB sensors have to chose between two light sources with different temps that really confuses it. It will pick one and the other will be completely out of whack.
BTW on the test I started yesterday, I had to switch to the GRP 27 because the 32a AGM hadn't been charged in a while and dropped to 12.1v. The 27 was freshly charged and sitting at 12.8v and holding. All of the emitters are fine and it only gets hot to the touch when you hold it for a while but not enough to make me need to let go.
