China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

All fluorescent lighting need a fluorescent ballast to work. Most ballasts hum for some minor diploma.

Ballasts for Twenty four inch, Seventy two inch as well as 96 " slimline lamps are sound scored C and also D and they are the least noiseless. Both magnetic and electronic fluorescent ballasts result in a slight humming noise; harmonics may be the technical expression.Slimline ballasts should only supply in industrial/commercial programs where noises is not a trouble. Energy saving ballasts, housing ballasts, and reliable state (electric) ballasts are audio rated A new.

By style an electronic ballast provides reduced harmonics and so the hum can be less noticeable than when you use a permanent magnet ballast. You may perceive them in a silent room. Even so, in most software, noise via sound scored A ballasts is protected up with the usual volume of ambient racket in a common room.

The loose magnetic ballast can be the cause of ballast hum. Make sure that ballast mounting nails are small.
