AC vs DC LEDs

Benefits of AC LEDs mainly relate to the reduction/elimination of associated electronics. Components removed can include a voltage regular, power transformer, diode rectifier and filter. The benefit of removing these components is that cost, lifetime and reliability are improved while the more compact size is also beneficial.
