Hi Susan, Here is a link to a post where someone did an AH Supply Retrofit on their Eclipse 3 30" hood. http://www99.epinions.com/review/Marineland_Eclipse_3_Filtration_Illuminatio n_System_12_X_30_80434140/content_446886416004 (You may have to "Cut and Paste to get the whole URL) I have used AH Supply and they have very good reflectors and ballasts. I know that Erik has used them as well. A 1 X 55 watt kit runs $44.99. Here is a link to AH Supply (one of the donors for our General Auction) http://www.ahsupply.com/36-55w.htm Hope this helps!
