Lamp color & lumen output regulation
A VS metal halide electronic ballast has less than ±
0.5% change in output power with a ±10%
variation in input line voltage, and less than ±
2.0% change in output power over the full
range of accepted ansi lamp voltages. the result is
excellent color stability. A typical "magnetic-lag" ballast
has more than ±15%
variation in output power with a ±10% variation in
input line
voltage, and an additional ±20% change in
output power over the full range of accepted ANSI
lamp voltages; resulting in very poor fixture to
fixture color stability and consistency.
Energy savings
A VS metal halide electronic ballast uses approximately 10%
to 17% less energy than a "
magnetic" ballast.
Improved lumen maintenance
Typically, a VS metal halide electronic ballast extends lamp
lumen maintenance from 5% to 15% versus a "magnetically" ballasted
lamp.
Small size & light weight
The VS metal halide electronic ballast family offers extremely small and lightweight
designs compared to large, heavy magnetic ballasts. |

Heat losses
A VS metal halide electronic ballast has a higher efficiency
and therefore much lower heat losses than magnetic ballasts.
One piece assembly
The VS metal halide electronic ballast replaces the ballast,
capacitor, and the ignitor of the "magnetic" ballast
systems in one integrated unit.
High power factor
A VS metal halide electronic ballast has a power factor greater
than 0.95, much higher than that of a "magnetic" ballast.
Quiet operation
The VS metal halide electronic ballasts are sound rated "A" for
quiet operation in interior commercial applications. |
