small fluorescent lightbulbs??

[irrka]

Hi!
When i rented my apartment, i inherited it with a 4-bulb lamp with flexible necks for each bulb. But the lights are those tiny candle-looking ones and i haven't been able to find the energy-saver-daylight-spectrum fluorescents with the screw part that's same size (i wanted to "help out" the windowsill plants). Do those lights come in mini version or am i stuck with the regular bulbs?
Thanks,
Irene
