Hello. I was planning on using some 13 and 23 watt CFLs in clamp-lamps and I was having a hard time finding some 6500K bulbs in my area. The closest Lowe's doesn't have them in stock and the nearby Home Depot only has 5000K Daylight CFLs. I was wondering how much of a difference there would be in color temperature and appearance between 5000K CFLs and 6500K CFLs. Thanks.
