Detailed Product Description

> Product Introduction
Our 320W EB with 320W MH lamp has been tested by China and the United States National Laboratory (LBL), their results show its luminous efficacy is 120-130 LMW(lumen per Watt) which exceeds conventional MB 400W MHs luminous efficacy. Therefore it can be used to replace MB 400W MH and achieve high energy-saving.

AR/EB 320W for metal halide lamp is named King of Energy-Saving.
Compare luminous efficacy between AR/EB 320W MH and MB 400W MH:

Ballast result	AR/EB 320W MH+320W MH lamp	400W MB +400W standard MH Lamp	400W MB +High luminous MH lamp	Result
Luminous efficacy	120 lm/w	70 lm/w	95 lm/w	Luminous flux: AR/EB320W + 320W MH lamp exceed 400W MB + 400W MH lamp
Luminous flux	38,400 lm	28,000 lm	38,000 lm

Notethe luminous efficacy of AR/EB 320W MH is 130 lmw60Hztesting by US Light Source Institution.
Testing conditions: Outdoor, factory, building and business lighting with MB and AR/EB
Comparison of Performance and Energy Consumption (Consumption RMB 0.60/kWh)
We test a group of MH lamps (100pcs) with 400W MH + 400W MB (with capacitance) systems. Then we tested the MH lamps with 320W MH + AR/EB 320W,The lamps are on 12 hours per day.
Results are as follows: 

Ballast Type	Consumption)	Consumption/Yr	Charge/Yr.	Charge/Pcs	Luminous
400W MBWith capacitance	0.453×100	198,414	119,048.40	1,190.48	34400
AR/EB 320W	0.317×100	138,846	83,307.60	833.08	38720
Results	Save 30.02%	Save 30.02%	Save 35,740.80	Save 357.41
*According to this table,if we use AR/EB, we can save RMB 35,740.80 per year; and total luminous flux increases by 12%.
