LED lamp technology
Take current 20MA as an example

Power=Current*Voltage

     =0.02*3=0.06W

 

LED Power (3528 LED)=0.06W

If Panel light has 372pcs LED, then 0.06*372=22.32W

 

If Power factor is 0.95 (PF=0.95)

Power of lamp= Power of LED/PF=23.5W

 

How to count lm(lumen)

Take 3528 for example, LED warm white=6lm and cool white =7lm

 

So whole lamp =372pcs lm=372*7*0.75=1953lm
