if you screw a regular 110 incandescent (it's a 110 fixture ?) bulb in and
it lights, then the ballast is at fault

Was trying to figure out why my dusk to dawn light quit. Jumped the light
sensor and I could hear a slight buzz coming from the fixture. Unscrewed
the
70 Watt lamp and put my DVM across the socket. Found out there is a heck
of
a lot of voltage there. The DVM made an arcing sound and quit. Display
still
comes on but no readings. Opened it and found the fuse blown. Thought that
was it, but the meter is shot. How much voltage is in that socket anyway?
