Conversion bulbs make it possible to run a halide bulb from your sodium ballast or a sodium bulb from your halide ballast, eliminating costly ballast investments.

We recommend using a halide bulb during your plants' vegetative stage, then switch to a sodium grow light conversion bulb for the budding and flowering stages.
