More Info:

This bulb has an internal starter that is designed to be operated on simple "choke" magnetic ballast. Electronic ballasts will not work with this lamp or any 9W or 13W lamps which have internal starters, regardless of manufacture.
Will NOT fit "Mini-Mite" Osram bulb type sockets. *** FAQ:

Q. I have both 13W and 9W bulbs on your ballast kits. Why does the 9W look as bright or brighter than the 13W?
A. Remember that the visual eye is a very poor indicator of light intensity. The reason the 9W appear to be so bright is because the physical tube length is shorter than the 13W. Thus, it appears brighter to some.
