1. The bulbs are bad. (not too common with new bulbs)
2. The ballests are bad and need to be replaced. (this happens every so often)
3. The power source is bad or there is a broken wire or bracket somewhere.
In any case, I would suggest to replace the ballests first and then proceed to the power source / wires if the new ballests do not fix the problem.
Did you buy the light from us?
