1. No need to change the original circuit or parts, no influence on normal work. Very convenient for places where magnetic ballasts are widely used such as factory, school, emporium and supermarket etc.

2. Decrease self-energy consumption dramatically, over 35% electricity saved but lower cost vastly, so investment can be returned in a short term;

3. Power factor improved from 0.4-0.5 of magnetic ballast to 0.95;

4. No need to use starter, preventing from frequent replacing;

5. Quick start without noise, 40% improved luminous effect, 10% improved luminance, 82 improved CRI for real colors;

6. The lowest starting voltage fall to 170V, the lowest starting temperature fall to -10 degree.
