"Cold cathode devices typically use a complex high-voltage power supply with some mechanism for limiting current flow. Although creating the initial space charge and the first arc of current through the tube may require a very high voltage, once the tube begins to heat up, the resistance to current flow begins to drop, requiring a gradually lower voltage to maintain operation. In the case of tubes with an ionizing gas, the gas can become a very hot plasma where electical resistance greatly reduced. If operated from a simple power supply without current limiting, this reduction in operational resistance would lead to damage to the power supply or the tube electrodes from overheating."

So it'd require a specific power supply from what i understand otherwise the life of the light would be greatly reduced. The question is, how do plants react to it? How many will you need? Would it be a combination of specific spectrum's, like LED's ?

I've never seen CCFL applied to plants.. anyone?
