Product Overview
OSRAM SYLVANIA's QUICKTRONIC High Efficiency (QHE) series delivers up to 6% additional energy savings over standard T8 low-power electronic ballasts, without compromising light output, and offers maximum savings versus F40T12 magnetically ballasted systems.
Actual system lumens, mean lumens, wattage, and efficacy vary slightly depending on which OCTRON lamp is paired with this ballast; the figures above reflect the FO96T8/XP OCTRON SUPERSAVER pairing.
