No. The cheap 4 foot fixtures contain a tar, iron and wire ballast and
these must be matched to the lamp length. For about $40.00 (see
http://www.grainger.com ) you can get an electronic ballast for T-8
flourescent tubes which will drive any lenght T-8 bulb up to four feet. The
electronic ballast will produce more light per watt of input power, improve
your lamp life, and give you brighter teeth and fresher breath ;-).

Home Depot sells the sockets. Get a few of these and screw them into your
wood hood.

See the the FAQ on lighting at actwin.com. All the issuses have been
covered ad nausem.
