Magnetic ballast :
1.UL listed (American standard)
2. Wide ranges from250W to 1000W for MH/HPS
3. Durable

 

Ballast case is beautiful looking and is an iron-core inductor coil, the nature of the inductor coil when the current changes, caused by magnetic flux in the coil will change,

resulting in induction electromotive force, its direction and

current in the opposite direction, thereby hampering the current changes.

It is used for the many kinds of lighting.

2.Standard & Voltages:

This kind is specially UL listed (American standard) with two gears,

like 120V,240V. It is very flexible and convenient for multiplex voltages' use.

3.Why you choose it? 

A. We professionally provide250W up to 1000W, like 250W, 400W ,600W, 1000W.

B. It specially for MH or HPS lamps or for both MH and HPS lamps.

C. This inductance ballast is more durable and everlasting than electronic ones.
