Beschreibung
Zusammenfassung:	A lighting device comprises rectification circuitry configured to produce rectified alternating current (AC) from input AC comprising a plurality of cycles. The lighting device further comprises lighting circuitry coupled to the rectification circuitry. The lighting circuitry comprises first, second, and third sets of LEDs. The sets of LEDs are configured to turn on in sequence at least twice per cycle to together develop an output level of at least about 2000 lumens.
