Sodium high-pressure lamps like this Osram Vialox 150W are the most efficient lamps for the plant breeding, since they have the best conversion of Watt (current consumption) in lumen (quantity of light). They are used by most growers for both the vegetative, and for the flowering phase.
This illuminant can be operated exclusively with an appropriate 150W fluorescent lamp ballast and E 40 version.
To increase the effect of the illuminant, you should additionally assemble a reflector.
