	It's okay, you can say Radio Shit on the Net. :-)

	What you want is an F4T5/BL or F4T5BLB fluorescent lamp, made
by General Electric and other vendors.  This is a 4-watt lamp, approximately
6 inches long and 5/8 inch in diameter.  It is a miniature bi-pin lamp
which is designed for a pre-heat circuit (although with high voltage and/or
high frequency excitation, it need not be run as a pre-heat lamp.

	Try any wholesale electrical supply distributor, such as Graybar
Electric.  I would guess the lamp to be around $ 5.00 or less.
