The "voltage" of a ballast (e.g. 120 V) refers to the line voltage coming from the power source and is connected to the ballast.
Photosynthetic Photon Flux (PPF)

Photosynthetic Photon Flux (PPF)

The measurement of micromoles that the bulb produces. Indicates how powerful a horticultural bulb is.
Average Rated Life (hr)

Average Rated Life (hr)

A measurement of the average length of time, between first use and the point when 50% of the lamps tested have stopped functioning, , using an operating cycle of 3 hours on, 20 minutes off.
