None electrolytic condenser
⊙Maximize LED Tube life span because Smart Buck is not used electrolytic Condenser
⊙In case of LED Driver which is used electrolytic condenser, When the temperature is increased 10˚c, LED Tube life
    span is reduced 50% (ex, Electrolytic Condenser can be used 1000 hours at 85˚c / 3000 hours at 70˚c  )
⊙Smart buck is using Mylar capacitor which can be used 100,000 hours at 80˚c/ more at 70˚c

Flicker free
⊙Flicker free ( pls, see  two picture : Flicker and Flicker free)
⊙Ripple of luminous flux is less than 3%, Flicker free is verified by Digital Camera
⊙As study result from Pacific Northwest National Laboratory (PNNL) of US Energy Department, If human expose    "Flicker phenomenon" for a long time, it caused discomfort, helplessness, headaches with epileptic seizures even visually
   inappreciable weak level.
