what\'s improvement between old model and new model?
 

1.better power supply which can 100% pass emc test
2.Led  temp less  15degree comparing to old model to ensure good lifetime of lamp
3.Lamp watt. reduced but keep the same lum output because of high efficiency of led used..
4.old lamp efficiency is 65lm/w but now it\'s 100lm/w ,,that\'s why we can reduce power and heat .

5.no fan inside to cause noise or additonal potential problem.
6. the outlooking and measurement is the same to to old model.
7. every led can Work independently, one led failed ,NEVER effect other led.
8.OVER  TEMP AUMOMATIC PROTECTION DESIGN(watt. reduced with temp increased)
