Quantum Digital ballasts use switching electronics and small frequency inductors to control
current and voltage to the lamp. They contain a ‘microprocessor’ similar to what’s used in a
home computer. This allows Electronic Ballasts (or E-Ballasts) to run both M.H and HPS
lamps, make adjustments for based on the type of lamp it’s running, and will even
compensate for degrading lamps by increasing output! (Also Quantum’s have a sealed
Bearing Cooling Fan that has enabled massive reliability over the Lumateks).
