Flourescent lights humming?

I just put 3 flourescent replacement lights in my bathroom (shaped like a
spiral, meant to replace the incandescent bulb in the same socket).
When I turn on the power there is a very audible hum. I know that
flourescent's can hum but did not think it would be this bad. Is the
humming a possible indactor of another problem? I can't have a bulb that
makes this sound in a small bathroom.
The spirals normally do not do this humming, bit I have found a couple
that did. One was a 27 watt model and the other was a 30 watt model.
I have also known heat buildup problems in some fixtures with higher
wattages, and even some complaints of early failures of 42 watt ones
operated base-up apparently resulting from heat. I also saw a possibly
heat-related failure of a 24 watt spiral, and those have been replaced by
23 watt ones due to improvements in efficiency of the electronics.
In addition, I have seen a slight trend of color of spirals being
slightly harsher with higher wattages as wattage increases past 23 watts.
As a result of all of this data, I might suggest to use 23 watt ones if
you were using a higher wattage. 23 watt spirals have light output a
little over halfway from "75 watts" to "100 watts" of "standard
incandescent" "equivalence".
The next step down in wattage in spirals is the 18-20 watt range, with
18 or 19 now being the norm here. Those have light output about that of
75 watt 120V "standard incandescents".

Thanks for the info. These are 23 watt bulbs (100 watt equivalent), brand
is "Bright Effects" item# 153972. I tried in a diffrent socket and all for
bulbs (was a 4-pack) still have the hum.
Will have to take them back to Lowe's. I hope they don't give me any
problems becase the package is mangled.
Sounds like you are saying that going with a lower wattage might reduce the
hum. I like the brightness though so I might try another brand and see if I
get lucky since you and others say that a hum is not typical.
Thanks for the reply.
