HPS bulbs need a separate ballast to function and can't just be screwed into a bulb socket. These HPS bulbs produce more Watts (and are more expensive in terms of operation) than regular plant lamps, it is advisable for the "smaller" grower to revert to low-priced alternatives like energy-saving bulbs or fluorescent lamps.

The light quality and efficiency of HPS lights is very high, yet they get very warm, which may make the climate control more complicated.
