Only if it is an electronic ballast that does not care about bulb length -
in a shoplight, it's going to be a cheap tar, iron, and wire ballast. Tar,
iron, and wire ballasts need to be specified for bulb length, diameter and
wattage. Electronic ballasts are constant current sources and they regulate
the current to get the necessary voltage to fire different length bulbs,
they need to be specified for bulb diameter, and you should make sure the
bulb length is within their acceptable range. GO to http://www.grainger.com
or Home base and check out the electronic ballasts.

Buy the ballast and the plastic bulb sockets. Build the rest.


"BRONX ANODD" (tm) in organic forms with full American violence emitting,
is three-dimensional curves demonstrate mystic movements as if they were of
unknown life. The body with well trained muscles but no extra flesh dashes
is the dark with sharpened knife-like brilliance emitting. Now, nobody can
stand in his way "BRONX ANODD" has just released hot.
