Review on 💡 Efficient Lighting Solution: Lithonia Lighting WF4 LED 30K - Illuminate with Energy-saving Efficiency by Ricky Habbani

This is an overview of the WF4 model. There is some confusion as to how they fade. Some reviews mention a 0-10V system with gray and purple wires. The spec lists 0-10V as an option for them. However, dozens of Lithonia Wafer "cans" I used during my reconstruction do not have such a scheme. I've even opened up a backbox that has "no user-serviceable parts" and no connections for 0-10V dimming. Really, it's a lot easier. Just buy a good ELV dimmer and you're good to go. There is no hum or flicker. It works better than expected. I use a Lutron SELV-300P-WH dimmer with them.
