Fluorescent Ballasts

Fluorescent Ballasts - Electronic

High frequency electronic ballasts offer high-quality lighting performance with efficient energy consumption. A variety of lamp ignition methods can provide further energy efficiency and/or lamp life improvement.
· Energy costs can be reduced by as much as half versus electromagnetic ballasts
· Wide variety of lamp starting methods for energy efficiency and prolonging lamp life
High frequency operation operates lamps more efficiently and eliminates hum and visible flicker

Fluorescent Ballasts - Magnetic

From their rugged steel casing to the uniform winding of the coil, superior materials and construction make Advance electromagnetic ballasts the choice for consistent operation and reduced hum.
· Uniform, firmly wound coils made of highest quality annealed wire assure consistent operating characteristics
· Special thermal-pliable compound dampens vibration and ballast hum
