I've seen people recently mention having success using 48" F32 T-8's with color temperatures in the 5000k to 65000k range. I've looked at Home Depot, Builders Square, True value & Ace hardware stores, and several lighting supply stores and those that have any T-8's at all are the cool white types in the 3000k to 4000k range. My question is, where are people finding these higher temperature bulbs? Matt
