High-CRI ac LEDs beat dc LED efficacy, price

Working from 110 to 220-Vac power sources, the Acriche 4 ac LED has an efficacy (luminous efficiency) of 75 lm/W, surpassing competing dc LEDs. Further, the devices will cost 10% to 20% less than dc devices.

With a color-rendering index (CRI) greater than 85, the

Unlike dc devices which require complex driver circuitry, the ac LEDs need only a simple, inexpensive diode bridge (full-wave rectifier). The A4 uses 50 Vrms per package, and 110 to 220-Vac operation can be achieved by connecting multiple devices in any manner needed. (Less than $1 ea/ prod qty — available this quarter.)
