You don't think the light setup in the book is legit??
Best idea I have seen for hanging multiple cfl's would be the light bars they make to go over sinks and vanities. You can get them with 2-6 sockets. Under $20.00 at the big box stores. SOme have used them and added y's to put two bulbs at each socket. DO a search, read some journals, don't questions the legit. VV
