What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Lutron Caseta Diva Smart Dimmer Switch (DVRF-6L)
One whitelisted tester — PCWorld/TechHive's Michael Brown — published a hands-on review of the Lutron Diva Smart Dimmer (DVRF-6L), calling it the smart dimmer to buy. He praises its understated paddle-and-slider design, no-neutral-wire install, and flicker-free dimming of a tested LED fixture, but flags the mandatory hardwired Caseta Smart Hub and Lutron's unclear Matter stance. No lab-measured numbers were published. (1 sourced review, 1 lab-tested.)
Praised: Understated paddle-and-slider design that blends in; Installs without needing a neutral wire; Dimmed a tested LED fixture nearly off with no flicker.
Flagged: Requires a Caseta Smart Hub hardwired to the router; Lutron's uncertain stance on the Matter standard.
