Usually your 48" bulbs are going to be 40w - check any standard shop light. The T designation is also measured in inches, 1/2", 1", etc. so when you call around just ask for your wattage and the diameter of the bulb.
Be very wary of a mixed bag of Malawis. I'd bet that many of these that can't be identified are hybrids. I have been burned this way before, so you really need to know what you want and make careful selections. If your importer is trusted and knowledgeable then that's a huge plus, but I thought mine was, too, and I am having to completely re-do my ARLC because of not knowing what I had.
Tony - thanks for the links and the clarification - I thought we were talking about standard bulb reflectors that are mounted inside the fixture. I still think you should call AHSupply.com and get their advice, FF.
