The Lutron Diva DVLV-603PH-IV is a 600VA magnetic low-voltage 3-way dimmer in clamshell retail packaging, suited for residential and light commercial MLV transformer-based lighting control at 120V. The large paddle switch handles on/off switching while the captive linear-slide adjusts brightness, and a built-in soft-glow nightlight aids visibility in low-light conditions. Compatible with standard single-pole and 3-way wiring, it fits a standard designer wallplate opening and ships in ivory gloss finish.
