Wife bought a light that uses a JD/G9 bulb( 40 watt.) Having issues finding this type of bulb locally. This is a G9 ( loop wire) type with ceramic base. Can I use one of following: 1) an ordinary G9 loop wire bulb no ceramic base 2) a JCD / G9 bulb ( stiff flat wire loop type) and 3) a G9 bulb with hard flat wire loop base no ceramic base?
