Advance Electromagnetic Ballast, F32T8 Lamp, 32 W Lamp, 35 W Wattage, 120 VAC, 0.32 A, 60 Hz Frequency, Rapid Start, 50 deg F Minimum Starting, Total Harmonic Distortion: <15 %, Power Factor: 0.91, 1 Lamp, Ballast Factor: 0.95, 9-1/2 in L x 2-3/8 in W x 1-1/2 in H Dimensions
The slight hum present in fluorescent lighting installations originates from the inherent magnetic action in the core and coil assembly of the ballasts. This hum may be amplified by the method of mounting the ballast in the fixture - the fixture design - and, more often than not, this hum is amplified by the resonant qualities of the ceiling, walls, floors and furniture. In planning a lighting installation, careful consideration must be given to the selection of the fluorescent lamp ballast, the lighting fixture and room componets. These precautions will help to achieve the quietest installation possible. The choice of fluorescent lamp ballast should be made on the basis of selecting the onerated quietest for a specific location or interior as some ballast have a more discernible hum due to basic construction features and electrical ratings.
