Need to find up to three ballasts for the following compact florescent lamps:
A ballast that will power an Osram 9 watt, GCF9DS/G23/SE/OF compact florescent lamp, Item number 21299. It is UV-A spectrum. It also has a description of: Dulux S & L Blue 365nm 9W/78. Its a 2pin G23 lamp, 144mm long.
A ballast that will power two of the above.
A ballast that will power the longer 18w version, Dulux S & L Blue 365nm 18W/78 Osram item number 56906.
Will greatly appreciate any help.
