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 MH’s luminous efficacy. Therefore it can be used to replace MB 400W MH and achieve high energy-saving.
Certificate:
Can sell without casing. for special lighting fixture.

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:
Note：the luminous efficacy of BB/EB 320W MH is 130 lmw（60Hz）testing by US Light Source Institution.
Testing conditions: Outdoor, factory, building and business lighting with MB and BB/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:
