Phosphor vs LED



The printed circuitry plate shows some powder like material?
The reason of no putting on of this lamp is the explosion of lighting tube, fatal defecting phenomena occurred in the Neoball lamp.
Is it true to be Neo?
But now, even uptodate this kind of phospho tube small light is down to date, now is the time for much more less current consuming LED light.
So, phosphor type small lamp is discounted at half prices.
