Our verdict

The WiZ Clear Filament A19 is for fixtures where the bulb is the decoration: clear glass, a visible LED filament, 800 lumens of tunable white, and Matter onboard at a budget tier. It gives up color and fixed-amber nostalgia in exchange for white that actually adapts from breakfast to evening.

What we like

  • Clear glass shows the LED filament honestly in exposed fixtures
  • Tunable white lets one bulb swing from morning task light to evening warmth
  • 800 lumens at 7 W is bright for a filament design
  • Matter and Wi-Fi onboard, plus WiZ motion activation with a second bulb

What to watch out for

  • White only, so no color scenes in the pendants
  • Filament output is still mood light, not whole-room task light from a single bulb
  • Tunable range endpoints vary by app setting compared with dedicated ambiance models

What owners report: WiZ Clear Filament A19 Tunable White Smart Bulb (1-Pack)

Synthesized from recurring themes in long-term owner feedback.

Most praised

  • The clear filament reads as a design feature in open pendants, not a bulb hiding in a shade
  • Owners praise tunable white for pendants over a table that hosts both homework and dinners
  • Motion activation with a second WiZ bulb makes entryway pendants feel automatic

Common complaints

  • A single filament bulb still leaves a big room underlit, so groups are the real purchase
  • Buyers wanting a fixed amber cafe glow should pick a dedicated amber filament instead
  • Wi-Fi setup quality depends on the router like every hub-free bulb

Who it is for

Pendant and open-fixture owners who want the filament look without giving up smart white tuning.

Filament looks, honest output

Filament bulbs usually trade brightness for style. At 800 lumens from 7 watts, this WiZ matches a standard bulb's output while keeping the clear-glass filament silhouette, so a pair over a table genuinely lights dinner instead of merely decorating above it.

Tunable white beats fixed amber for mixed-use rooms

A dining pendant hosts homework at daylight white and dinner at candle warmth. Tunable white lets the same fixture do both, where fixed-amber Edison bulbs only ever do the evening half. Buyers chasing a permanent cafe glow should choose amber; everyone else gets more life out of tuning.

Platform and extras

Wi-Fi plus Matter means no hub today and platform options tomorrow. Paired with a second WiZ bulb it joins the SpaceSense motion system, and the WiZ app's schedules handle the daily on and off without a wall dimmer, which filament bulbs must never sit on anyway.

Questions, answered

Is the WiZ filament bulb dimmable?

Yes, digitally in the app and by voice. Never put it on a legacy wall dimmer; smart bulbs need constant power.

Does it do colors?

No. This is a tunable-white filament. For color, choose the WiZ Color A19 or another full-color bulb.

How many do I need over a table?

Two to three gives social, even light. A single filament bulb remains accent light in a large room.
