WHY LED LAMPS SAVE ENERGY?
  1. LUMINESCENCE EFFICIENCY GREATLY RAISED，AND HAS A BIG POTENTIAL TO GET HIGHER CONTINUOUSLY 2.LED BELONGS TO DIRECTIONAL LUMINAIRE, AND HAS A HIGH LIGHT UTILINATION EFFICIENTCY. 3.LED LAMPS ARE CPMVENIENT FOR LUMINANCE CONTROL, AND CAN REALIZE LOTS OF ENERGY-SAVING MODES. 4. LED LAMPS HAVE GOOD COLOE RENDERING
WHY LED LAMPS HAVE LOW OPERATION COST?
1.LED LAMPS SAVE ENERGY, REDUCED THE FEE OF ELECTRICITY COST. 2.REDUCED THE CONSTRUCTION COST OF POWER DISTRIBUTION SYSTEM（CABLES, TRANSFORMER, DISTRIBUTION BOX, CABLE BRIDGE AND SO ON）. 3.LOW COST OF DAILY MAINTENANCE AND REPAIRING.

Cost Efficiency
THE LUMINOUS EFFICIENCY (LM/W) OF OUR LED LAMP IS 80 LM/W. THE EFFICIENCY FACTOR OF OUR LAMP IS 85%. THUS THE REAL LUMIOUS PER WATT OF OUR LED LAMP IS 80 X = 68 LM/W.
THE AVERAGE LUMINOUS EFFICIENCY (LM/W) OF INCANDESENT LAMP IS 22 LM/W. THE AVERAGE EFFIENCY FACTOR OF INCANDESENT LAMP IS 60%. THUS THE REAL LUMIOUS PER WATT OF INCANDESENT LAMP IS 22 X 0.60 = 13.2 LM/W.
THUS OUR LED LAMP IS AROUND 20% EFFICIENT COMPARED TO INCANDESENT LAMPS.
