	   This behavior is typical of aged fluorescent tubes.  They
	don't just stop like an incandescent bulb, they get hard to
	ignite.  It may be excacerbated by an old ballast coil, but
	try just replacing the tubes, first.

	   While you're at it, try a different type of pigment formulation.
	Try Cool White Deluxe.  It costs a little more than the ubiquitous
	Cool White, but it has a broader spectrum with more output at
	the red end, and people look better under it.  Or try Chroma 50
	by GE.  It is also broad spectrum (matching indirect skylight)
	and plants love it, too.
