To save some money, I was going to try to use some battery-operated LED disc lights that I picked up from Costco a couple of years ago. Do you really think the fluorescents make that much of a difference? If so, I'll invest the money now on them. The RHPs seem really expensive compared to the flexwatt, but I also don't want to end up spending the money on the flexwatt only to discover that they are not sufficient and I still need the RHPs. Any suggestions?
