Grrr. I will be irked if I have to eat a brand new non-working ballast.

I would also be more irked if I bought another new electronic ballast for
an unknown problem and I had to eat it /too/ while the light still didn't
work properly.

I really feel that I should make a diagnosis somehow.


What is it with this light. There are only a couple of things that can be
wrong.

From what I have read, you have bought new bulbs and a new ballast.

Make sure the make sure the bulbs and the ballast are the same. You have
two power wires, the black and white, then only about 4 more wires. Make
sure the wires are going to the correct places, not just by matching the
colors. Then the connections at the sockets the bulbs fit in could be bad.
Also make sure the ballast case is grounded to the light fixture.

How many wires are comming out of your ballast and what color are they ?

If your bulbs are marked raid start, the ballast should have 8 or 9 wires.
The green, black and white (standard house colors) and 2 each of blue, red,
yellow.
