I have this light kit: http://www.ritzcamera.com/product/EP4462179.htm Now I need new bulbs for it, I thought I had ordered bulbs for it but they were not the right ones. They were huge everything else was right about them but the size from what I could tell. Here are some picture to compare them: the yellow one is the one that came with the kit, the white cardboard one is the one I am haveing to send back. Now my question Can I go to a normal hardware store or are these special bulbs?? I am worried about my white balance in all.
