Among AnRui electronic
ballast series, there are two models named ‘King
of Energy-Saving’, which are 320W and 175W for
metal halide lamp. The lumen efficacy and power
efficiency produced by 175W EB with 175W MH
lamp has met and sometimes exceed those of 250W
MB with 250W MH lamp. Thus, AR/EB 175W MH is
a perfect replacement for old conventional MB
250W MH.

From the conclusion of the test report, 175W EB with 175W
MH lamp saves energy outstandingly.

Comparison of Performance and Consumption(Consumption RMB

We test a group of MH lamps (100pcs) with 250W MH + 250W
MB (with capacitor) systems. Then we tested the MH lamps
with 175W MH + AR/EB 175W. The lamps were powered on 12
hours per day.
Results are as follows:

*According to this table,if
we use AR/EB, we can save RMB 24,966.00 per year; and total
luminous flux was increased by 6.7%
The examples only show direct energy saving. With the AR/EB,
you can acquire more saving as follows:
It has a power factor greater than 0.99 and total harmonic
distortion less than 10%. Therefore it has very little influence
on the electronic web. It consumes 50% less power than MB,
thus reducing cost of investment and ease the maintenance
of power equipments such as, total power circuit, transformer,
etc.
AnRui EB contains automatic Full-function Protection circuit
from pulse soft star and modulating frequency. When open
or short current occurs the self-protection circuit will
be active automatically shutting down the output power of
EB. The built-in adaptive control system guarantees AnRui
EB to work efficiently and dependably with different MH
or HPS lamps' discharge characteristics of different manufacturers,
old and new. This system can automatically and perfectly
adapt to different lamp characteristics preventing lamp
cathode being impacted from rush current, thus reaching
high luminous efficacy and extending lamps' life.
